Get fantastic sound from your digital audio sources

How do you get sound from your PC? If you're still doing it the old fashioned way, by plugging into your computer's headphone jack, then you should definitely know about the Audioengine D1. This tiny, outboard digital-to-analog converter simply connects to one of your PC's USB ports, and bypasses your computer's built-in audio circuitry.

By processing your digital music files outside the noisy environment of your computer, you'll hear far more dynamic and detailed sound that you can really savor on your headphones, powered speakers, or stereo system. The D1 also includes an optical digital input so you can enjoy similar improvements in sound with your old CD player, network music streamer, set-top box, game console, or almost any other audio device with an optical digital output.

Make your headphones sing


The plug-and-play D1 delivers sparkling clear sound from your computer to your headphones, stereo system, or powered speakers (Audioengine A2 speakers shown

A pair of good headphones can give you a real taste of high-end audio without breaking the bank. But you're unlikely to find high-end sound coming out of your headphones if you plug them straight into your laptop. That's because most computer manufacturers use low-cost, low-performance circuitry to power their headphone jacks. The headphone amp inside the D1 will quickly spoil you. It delivers richer, deeper bass and clearer highs while revealing layers of musical detail that ordinary headphone jacks obscure.

Easy plug-and-play operation

Adding the D1 to a system is simple — just plug it into any USB port on your computer, where it will install itself and be ready for use in a matter of seconds. From there, just plug in your 'phones, or connect the preamp outputs to your powered speakers or stereo and you're done. The handy volume knob lets you control listening levels for both headphone and preamp outputs.

Improves and amplifies music perfectly! I am very happy that I purchased this DAY. Well worth the money.

Pros: Sound quality, amplification, small size

Cons: None

Hearing is believing

Vaughn from San Diego, CA on 10/14/2018

Crutchfield Customer Review (What's this?)

I listen to music through headphones at work, and I never knew I was missing out of a fuller audio experience. I am pleasantly surprised that the Audioengine D1 does what it says it does, which is make the music coming from my laptop sound better. The setup and use are simple. You plugin the USB cord to the laptop and the other end to the Audioengine, plugin your headphones to the mini-headphone jack, and play your music. The volume knob on the Audioenngine controls the sound. Even through my standard Apple headphones I could hear audio I had been missing before. It was quite a treat for the first few songs until eventually I got used to the new normal. How quickly will take our modern marvels for granted.

Pros: Better sound from headphones Volume knob Easy setup and use

Cons: Big investment for just headphones Only supports mini headphone jack

I have nothing to compare, but this DAC sounds great with my Focal Clear headphones

Pros: price


Great sound; Perfect for Home or Travel

Patrick from MD on 5/13/2018

Crutchfield Customer Review (What's this?)

Simply put, I wish I bought this sooner! Sometime again I bought V-Moda M100 headphones, which are supposed to sounds awesome. I was never impressed with their quality even when plugged into my Denon received. That was until I bought the Audioengine D1. I bought it for a upcoming trip so that I could have good quality sound rather than the noisy output my laptop makes from the headphone jack. I also figured that at home I can use it to connect both my primary computers' audio output to one set of speakers via an old Onkyo receiver. I haven't hooked it up to the Onkyo yet, but I can say that I was truly impressed with just the USB connection to my laptop. My FLAC files sounded amazing and there was finally a good amount of low end. I was also quite surprised by the upper frequencies as well as the clarity of the music. The fun part was I finally could hear what I knew all along, Amazon Music stream is terrible quality (even on their highest setting). I still intend to purchase a more purpose built DAC/amp for my computer desk setup, but this is perfect for now and great for traveling. It is small, lightweight and comes with a carrying bag so you can put the USB cable and the DAC together in one convenient place. I also love the feel of the volume knob, great quality. For reference, I have tested it with various Drum and Bass (Electronic music, very bass heavy, but full spectrum music) and Anuna (Irish choral).... both sound great from FLAC.

Pros: Great Sound Lightweight Perfect for travel Comes with carry bag & USB cable

Cons: Headphone jack points slightly down (barely a con)

My Starter Equipment into the Audiophile Life

Pablo from Indianapolis, IN on 1/15/2018

Paired with my AKG 712 Pros and the sound is much clearer, less muddled, separation, and more. Am looking forward for a portable headphone amp maybe the D3.



Audioengine D1

Crutchfield customer from Pulteney, NY on 1/9/2018

Crutchfield Customer Review (What's this?)

This has worked fine with my MacBook Pro running the free Mac "Sierra" upgrade. I added this comment because I read comments where people were having compatibility problems with Mac "Yosemite". I have had no compatibility issues with Mac "Sierra". I gave it a 5 star rating because I was required to rate it before I could comment and I've had zero problems. I have never had a DAC before so I'm honestly not qualified to comment on performance related to audio quality. It is made in China like most things. So if you have a Mac product and you are having problems, try upgrading your software.

Pros: It works.

Cons: Nothing noted.

Small, simple, basic

Andrew from Palo Alto, CA on 6/22/2017

Crutchfield Customer Review (What's this?)

Small and simple with a headphone jack. Variable output on both the RCA output and 3.5 mm headphone jack. The sound is bass heavy. I had to turn down the volume on my sub-woofer with this DAC. It sounds fine, nothing obnoxious, but didn't get me involved with the music. My advice would be to save and then spend a few dollars more for something better.

Pros: Small Volume Knob

Cons: Better available for not much more money

Solves the tv's problem of only having optical audio-out

LG TV user from NYC on 3/5/2017

Crutchfield Customer Review (What's this?)

I purchased a fancy-shmancy tv that didn't come with a simple old-fashioned RCA or headphone audio-out. It came with optical audio out ONLY (Toslink). What to do?! I bought this!! It makes it possible to use my wired headphones with the tv. I also plug in the base transmitter of my wireless (non-Bluetooth) headphones. They both sound better than ever because of the sound boost from amplification. The conversion from digital to analog output is flawless. Instead of being bulky, it's a stylish little device that looks at home next to the tv. To plug it in and keep it powered, a printer-USB cable is provided. (The printer USB end goes into the D1, the standard USB end goes into a wall-outlet USB charger that's not provided but is available everywhere for under $10.) At just under $170, it's a very reasonable cost to solve the HDTV's problem of not having a regular audio-out. My TV sound is richer than ever.

Pros: Sound is excellent. Simple to use. Includes volume-control. Well-built. Nice curved styling. Good value.

Cons: Nothing negative to say about this device. It's solid.

Meh, save just a little more for something MUCH better

Guest from NJ on 1/6/2017

This one worked well from a compatibility standpoint, but was, for some reason, flat and lifeless to my ears. Perhaps it's the single ended connections, just not enough clarity and timbre of instruments. I exchanged for the Teac UD-301 which is astounding for the price. I say. save up just slightly more and you'll get an exponentially better product than this one. I believe AE makes a higher end model that is probably more of a quality product.



Great little headphone preamp

Michael from Kalaheo, HI on 1/4/2017

Crutchfield Customer Review (What's this?)

Excellent solution for headphone usage on the Samsung 4K Series 9 SUHD TV's One Connect Box - optical out and USB powered. Keep in mind a few settings on the TV are required: PCM audio and delay, under Expert Settings. Tech Support from Crutchfield easily guided me through settings processes. Five Stars.

Pros: Perfect solution listening by headphone on new Samsung 4K SUHD

Cons: None

Great Headphone amp.

Mike from Las Vegas, NV on 10/11/2016

Crutchfield Customer Review (What's this?)

This is a great headphone amp, good size, and fit and finish are impeccable. I think my expectations were a bit too high on what kind of improvement I would see over the DAC in my HP Pro Book. I assumed since my DAC was integrated in my laptop this DAC was going to be night and day on sound quality and after downloading some lossless files I am realizing iTunes and their poor quality audio files are the source of my problems. If your music library is mainly mp3 and iTunes I would say skip the DAC unless you just need a great headphone amp. But none of this is Audioengine's fault so instead of giving this the original 4 stars I was going to they will get the 5th star back.

Pros: Outstanding fit finish and overall quality

Cons: Will not make poor quality files sound good.

Much better

Richard from Maumelle, AR on 8/30/2016

Crutchfield Customer Review (What's this?)

For PC music listening, my Logitech speakers just weren't cutting it. Had an Polk RM7000 satellite / sub system laying around doing nothing so decided to hook them up to the PC (via an amp). Sounded harsh on the high end. Added the D1 between PC and amp and...WOW! Great high end and killer bass. Highly recommend!

Pros: USB powered



nancyandnorm from Sandwich, IL on 5/17/2016

Crutchfield Customer Review (What's this?)

Plenty of power for my Sennheiser HD598's. Definate improvement of sound quality using Bose Companion speakers.

Pros: Music files on computer are now better sound quality.

Cons: none

Nice little DAC

Steve from Ohio on 3/24/2016

Crutchfield Customer Review (What's this?)

I have this DAC connected to my laptop then into a small bookshelf stereo in my home office and works great. So far no problems, sound quality is very nice.

Pros: Small, compact, easy to install

Cons: None

Audioengine DAC review

Rob from jackson, MI on 3/21/2016

Crutchfield Customer Review (What's this?)

been hearing about how good ear phone amps/Dacs help improve the sound of any headphones. So after a few years thinking about spending money on one i decided to buy this Audioengine D1 Dac. 1st must say it's very easy to use. just plug the USB cable to it and your ready to go. comparing it with 3 different in ear headphones and 1 over the ear headphone it definitely will boost the loudness that the earphones will go. Does it sound better? maybe a little compared to my Dell sound card with windows 10. I think it cleared up the mids and high's a bit on some of the headphones i tested. It definitely helps in volume levels which in turn makes things sound better. It like adding a bigger amp to your home system. I like the fact that it has a Optical audio input. Have not tried it with power speakers yet. Thats my next test. I am still not decided on this model or the N22 desk top amp which can use Passive speakers instead of power speakers with this D1 model?

Pros: nice size, comes with short USB cable, Built very well, has good connectivity for many uses, nice color power light, Helps with volume levels with any headphones. Sound is a bit better then computer sound card alone.

Cons: "non really" but maybe a little pricey for the amount of sound advantage you get over stock computer sound card if buying for that purpose alone.

Excellent sound quality

Phil from New Mexico on 12/17/2015

Crutchfield Customer Review (What's this?)

This unit provides an excellent sound quality. The construction is solid and the volume control for the headphone is very smooth. My primary complaint is that it doesn't have a "line input" for playing mobile devices. It appears to be designed for only computer use or headphone use. Another negative is that the USB circuitry doesn't appear to be asynchronous (I couldn't find any data that indicated that asynchronous USB was a feature of this DAC) . If it had both a line input and asynchronous USB capability, it would definitely rate 5 stars. For what it was apparently designed for (computer audio and headphone ), it's an excellent unit.



Audioengine D1

Jace from Honolulu, HI on 11/16/2015

Crutchfield Customer Review (What's this?)

The D1 is a must buy for anyone looking to get more out of their current setup. As others have said, bass is more pronounced and full, the highs are crisp. Awesome product, not to mention they power my (250 ohm) headphones nicely.



D1 full of quality at low price

Crutchfield customer from New York, NY on 9/28/2015

Crutchfield Customer Review (What's this?)

In general Audioengine products seem to be extremely high quality at great prices. The D1 is no difference. I have it connected to a mac mini outputted to emotiva 6s powered speakers. wow, the D1 really makes them come alive. one small minus is the D1 disables the OS volume control on the mac, but not a big deal because you just use the analog knob. this may be an issue if you are connecting the D1 to a TV, be sure the RCA or optical out from the TV has a variable volume output mode (this is not obvious).

Pros: great value, full clear sound.

Cons: none

A New Sound

VictorSF from San Francisco,ca. on 9/14/2015

Crutchfield Customer Review (What's this?)

Love how it brings new life to the music streaming through my Apple TV!



Amazing combined with a Sonos

Ross from Bloomington, Minnesota on 6/21/2015

Crutchfield Customer Review (What's this?)

I have my computer audioengine A2+ speakers connected through the audioengine D1. The computer is connected to the D1 with a USB cable. I then connected a Sonos into the audioengine D1 with an optical cable. I love that when I play music with the Sonos, it overrides the computer sound and just plays the Sonos music. The D1 gives priority to the optical cable, so I don't need a switch to switch between computer sound and the Sonos.



Audioengine D1

stuart7491 from South Carolina on 5/10/2015

Crutchfield Customer Review (What's this?)

So far so good, the more usage the better the sound



So much value

BigEd from Michigan on 4/11/2015

So I'm an audiophile who mostly listens to analog but wanted to try PC audio on my system. I've tried a lot of different USB DACs ranging from $30 to $2000 and this one fits perfect in my system.

Pros: It has great energy in all frequencies and is very resolving

Cons: None

Unstable in OSX Yosemite

Eddie from San Francisco, CA on 3/31/2015

Crutchfield Customer Review (What's this?)

My D1 worked great prior to installing OSX Yosemite. Since upgrading, the sound begins to decay and start crackling and the sound eventually becomes garbled to the point it cannot be listened to. Turning the unit off, then back does resolve it temporarily. This is done several times a day. Nothing from AudioEngine to resolve the problem.

Pros: Compact, easy to use.

Cons: Can't use under OSX Yosemite.


Furious from Oregon on 3/13/2015

Does not work with Yosemite. Very upset. It was working fine until a software upgrade messed it all up. Fix this problem now please.

Pros: Great while it lasted

Cons: see above

Awesome with A5+

md from Leawood, KS on 2/28/2015

Crutchfield Customer Review (What's this?)

I purchased the DAC because I wasn't getting the quality I expected out of my Audioengine A5+ speakers. After some research, I learned that the problem was likely due to the low quality headphone jack built into my Dell laptop. An audiophile friend of mine recommended the Cambridge Audio DACMagic, however, the DACMagic seemed like overkill for my computer system. Without doing extensive research, I chose the Audioengine D1 on the assumption that it would match well with my A5+ speakers. The difference was amazing. I feel like I have a genuine hi-fi system. I can hear tiny details that I never could before while listening to the same music on my iPod. I do not have exceptional hearing talents, but I can hear a difference using a DAC. Stunning combination. I get the best results from the audio files I ripped from CD or bought through iTunes. I get only a modest improvement from music I stream from Pandora One. The D1 works as intended and I am happy with the purchase.

Pros: Matches well with Audioengine A5+ speakers. Improves sound quality as intended. Visually attractive. Solid construction.

Cons: Had to make a leap of faith that it was a good purchase. Unsure how it compares with cheaper DAC alternatives.

Doesn't work with Mac OS X Yosemite

Keith from Utah on 1/30/2015

Just hope the product works when you get it. If there is a problem and you contact Audioengine tech support they will tell you it is somebody else's fault not theirs. In my case they blame Apple yet they admit they aren't even working with Apple to resolve the issues. Buyer beware....

Pros: None

Cons: Non functional

Does what it says

SWilson from Huntsville, Alabama on 10/2/2014

Crutchfield Customer Review (What's this?)

Great device that does exactly what it says. If you use a computer to listen to music, then this is a must have.

Pros: Small footprint, quality build, works as advertised.

Cons: USB audio is muted as soon as you connect the optical input, and you can't switch between input sources. That seems like a bad oversight on the part of whoever designed this DAC.

Good sounding unit!

Phil T. from Rockville, MD on 9/19/2014

The unit is small but well built. Controls desktop speakers and headphones. Both sound good to me - no distortion. Have used Audio Engine D1 for year and no problems.

Pros: Good sound, well made.

Cons: Just need glue tack tape to keep in place on desk.

Great Sound, Accessory Needed

The Old Fox from Watkinsville, GA on 9/16/2014

Crutchfield Customer Review (What's this?)

The sound from this unit is superb with high quality 32 Ohm headphones(e.g. Sennheiser HD 558s)

Pros: Great Sound, easy setup if your computer has full powered USB ports.

Cons: A good, full independently powered USB hub (about $20+) is needed to use this unit on laptops and other computers with USB ports that do not put out full power. On 300 Ohm headphones, the lack of USB power may prevent getting life-sized volume.

Great dac for your pc/laptop

Andy from Norwalk, CT on 8/29/2014

Headphone Amp Audioengine D1

Tim F from Fort Lauderdale FL on 6/19/2014

Crutchfield Customer Review (What's this?)

I suspect it may be low in power output although im not sure thats the problem 2Vrms. It sounds great, clarity is awsome and distortion probable cant be easy to mesure.

Pros: Operation is simple to set up with optical as it puts priorty on it (PC).

Cons: Another volt in out put may or may not correct the low bass broblem. I have to crank up the low end of my EQ (PC) to max to get flat responce. But im not sure if the headphones are a part of the problem (AKG 550). Have questians I have not had time to ask, Work. Some recordings have a much higher out put than others. This could go five star once I get this nailed down.

Cool device pass the break in period and still sounding perfect



Excellent DAC that does what it is supposed to

erniecolorado1 from Aurora, CO on 4/24/2014

Great product especially using Toslink port. In order to bypass the motherboard sound chip, which is always recommended in this case, since the external DAC is always higher quality by far, you need this product in USB or Toslink optical digital connections. I prefer the Toslink optical over the USB. Your motherboard needs to have the Toslink connection, which many do nowadays. If you look in the description, the Toslink gets higher resolution 24-bit/192 KHz than the USB connection does. I recommend a good Monster or Audioquest optical cable, short as you can have it. The sound is so pristine. NO background noise, no crackle or static at all. Just crystal clear sound. Get a good pair of speakers with at least a 6.5 inch bass/mid-woofer and you are good to go.

Pros: Superb sound to my Pro Monitors for music AND movies

Cons: Nothing that I can see or tell.

good sound but missing accessories

johnny_boy from new york,ny on 2/20/2014

Crutchfield Customer Review (What's this?)

I use this DAC to connect my Scientific Atlanta cable box to a set of JBL active speakers. From a sound point of view it sounds very good. No software to install. I just plugged in the toslink cable and plugged in the audioengine to a wall socket via a usb cable and ac/dc plug. The USB cable that comes with it is a joke. It is the shortest cable I have ever seen, so I had to get another one. The unit is vey small and I wish the volume control knob was bigger. Plus there are limited input types this device will accept. Another issue is it doesn't come with a usb to wall socket attachment, so you will have to buy one or use the one that came with a smartphone or some other device. But it does what I need it to do right now and it was a huge amount of money.

Pros: Fair price, sound quality

Cons: small size, missing accessories, no digital component connection

Delivers great sound

RonR from Davenport, IA on 1/29/2014

Crutchfield Customer Review (What's this?)

Not too long ago I purchased a new computer and, surprisingly, discovered it has a poor sound card. I have an iTunes music library on my computer that I like listening to through my desktop speakers. The sound that was being produced just wasn't cutting it. I did some research and found a lot of good reviews regarding the Audioengine D1. I decided to purchase one and it has proven to be a great decision. The sound it produces is very satisfying to my particular ears. Based on my experience with this product, I would highly recommend it.

Pros: Great sound. Simple to set up. I definitely feel it's a 5 star product.

Cons: Haven't noticed any.

Aurioengine D!

Victor K from Lake Worth, Fl on 1/8/2014

Crutchfield Customer Review (What's this?)

This product will blow you away. All I can say is wow

Pros: Makes your music sound great use with headphones or use with stereo receiver. I Love it and would not part with it. Thanks to Tech Support for helping me to hook it up

Cons: none

Audioengine D1 Heaqdphone amp

Rich C from Riverside, California on 1/7/2014

Crutchfield Customer Review (What's this?)

Got mine today the 7th of January as scheduled. A definite increase in volume and overall tone on the ATH-M50's headphone. The Audioengine D1 headphone amp is worth the investment. I'll be using the D1's analog outputs for my receiver in the very near future. Coupled with Cructhfield support team, there is no way you can go wrong. Their representatives called me twice to explain the product that I ordered. I'm going to buy another for my sons birthday coming up.

Pros: All the product features; increase in volume and improved tonal quality on both of my headphones.

Cons: None

Audioengine D1

Duditude from DE on 12/24/2013

Crutchfield Customer Review (What's this?)

Seems to work fine, paired with the Audioengine 5+. Not sure if its worth the extra $$ to go with this but I did and I'm fine with it. Be aware my first D1 did not work properly, thought it was defective. Crutchfield was awesome (as usual!) with the return, then the 2nd unit behaved the same. I plugged a 2.0 USB splitter into my 3.0 port (basically downrated my computer's USB port) and it worked fine. There is nothing in the literature that tells you this, found this solution on line.

Pros: It works, makes using the Audioengine 5+ speakers a little more flexible. Purchased from Crutchfield so the problems I had were handled awesomely.

Cons: Is it worth the additional cost? Had to return 1st D1 due to incompatibility with 3.0 USB port, downrating the port solved problem.

As advertised

Rich from Needham, ma on 12/15/2013

Crutchfield Customer Review (What's this?)

Bought this because the sound card in my brand new $2.5k laptop sounds like junk. This thing is awesome. Has trouble driving my Sennheiser hd600s, But they are very hard to drive. Makes my hd380s sound incredible. Paired them up with some A5s from the same company and this is the ultimate desktop audio solution IMO, suitable for casual listening, critical listening and even video/audio production. Good luck finding anything that performs as well near this price point.

Pros: Simple, small, sounds great

Cons: Can't think of any


Barry from Arizona on 12/6/2013

Crutchfield Customer Review (What's this?)

Over the years I have had several high-end audio systems,but limited space since I retired several years ago no longer will accommodate the large speakers and component system. While my new PC based near-field system is a significant step down from what I have been listening to, I have been very surprised and satisfied with the improved performance using the D1 DAC, This is a great product its price point.

Pros: Very compact, easy to install and performs as advertised

Cons: I wished it had two sets of line outputs, either two RCA or XLR and RCA, even if it cost a little more.

Great Upgrade

Nick from Cumberland, MD on 11/19/2013

Crutchfield Customer Review (What's this?)

This is a great little DAC/AMP. I've used the HiFiMan HM-101 in the past and it does a great job for it's price. But this is head and shoulders above that. Immediately noticed much fuller and detailed sound through my AKG K240 MK II's. If you are looking for a much more immersive audio experience I highly recommend.

Pros: Plenty of power (I'm not driving planar magnetic ear speakers) Detailed Uncolored

Cons: none

Audioengine D1 - Well worth the buy

Fred from Baltimore, Maryland on 11/19/2013

Crutchfield Customer Review (What's this?)

Everyone today is interested in video entertainment, and enhancements and features for that purpose. I'm sure there are still others out there, beside myself, who love music far more. I have a great audio system, including a set of Bose 901's and a pre-amp and power-amp from Emotiva. I recently purchased the Audioengine D1 so that I could stream high quality music from my computer to my audio system. There is nothing that you have to do but connect the unit to your computer, no special software is needed. Believe me when I tell you that words cannot describe how fantastic this setup sounds. If you love music as I do, you owe it to yourself to purchase this missing link and begin to enjoy all that the internet has to offer an audiophile. Very low cost compared to other DACs on the market. Very portable. No additional power supply required, being powered by the USB power buss.

Pros: Great value and addition for playing digital files from a computer system.

Cons: None whatsoever.

Big Sound, Little Box

BigRedCajun from New Fairfield, CT on 10/25/2013

Crutchfield Customer Review (What's this?)

I purchased the Audio Engine D1 because of cost and also the Audio Engine reputation. Also, I knew that I could get more from my computer system than what my stock sound card could deliver. I also wanted to retrieve a audio through the USB port to keep things in the Digital domain. I'm using an HP desktop computer and feeding an ART SLA-1, 100watt/chnl amplifier connected to a pair of Definitive Technologies SM-350 monitors. After quickly connecting the D1 (About a minute) using the analog out, I was on my way to what follows. First and foremost, the difference when I connected was not subtle. The Treble had much better pitch as well as greater definition. The highs were much smoother and warm while still having a great deal of detail and transparency. The bass was another issue altogether. It wasn't as defined or as controlled and it seemed to have a distortion that wasn't present in the treble range. After a quick run through of the gain settings from the computer and iTunes, adjusting the gain structure as required everything snapped into place. Now the Bass had great pitch definition and extension. The bass was had a much better dynamics and "feel". Vocals are uncannily real made possible by an awesome midrange. Both female and male vocals really shine, although darker male voices do come off a little lean. Artist such as Lou Rawls or Michael McDonald have a little less "amber" but all in all still pleasing and still warm sounding. The headphone out is Very Good. I listened using Grado SR80's, Sennheiser HD280 PRO's and the Audio Technica ATM-50's. All showed improvements similar to what I wrote above, each with their own character and each one easily disguisable from the other. For the price I can't imagine finding another DAC in this price range that could do better with as many features. I would put this in the same category as the Audio Quest Dragonfly and the HRT HeadStreamer.

Pros: A lot of Features for the money. Very Good sound in its price range. Solid Build Quality. Optical Input.

Cons: Would love to see a Pro Version with Mini-XLR out.

G J, from Ohio on 9/25/2013

Crutchfield Customer Review (What's this?)

OK, but just not quite there yet. It's a bit sloppy, loses composure with more complex material. Bass seems a little thin. Headphone amp needs more power and a cleaner sound. It's an improvement over a p/c sound card for sure, but not compared to some other products in a similar price range, or for not much more.

Pros: Convenient, easy to set-up and play, no drivers, well built

Cons: Bass, Headphone amp, sounds ok

Awesome product!

Sam from Chicago, IL on 9/16/2013

Crutchfield Customer Review (What's this?)

Great product. I bought it because my headphone port on my Macbook pro has some issues and wanted something to bypass it. This was absolutely the best remedy. The DAC is solidly made and the packaging is superior to most others. The sound quality is quite exceptional with good headphone/speakers. I would 100% recommend buying this!

Pros: Good sound, build quality, packaging

Cons: Maybe the price is bit high? I don't really care the DAC is too good.

Crutchfield Customer Review (What's this?)

Was very skeptical about this product but installed it on my iMac. Made a world of difference over the standard mic port. Amplifier is clean with no hum. Cleaned up the bass but especially the mid range. A little bit of a 3D quality. Plus I now have the mic port in front of me rather than having to reach around the iMac

Excellent little unit without the high price tag. I live in Hawaii and unbelievable how fast they got it here!

Pros: Perfect specs for the money. Easy to install and use.

Cons: None

Sound Great

treker88 from Long Beach CA on 7/22/2013

Crutchfield Customer Review (What's this?)

The Audioengine D1 has great design and build quality, and the audio is really good. I'm using it with the USB connection (haven't tried the optical input yet), Windows 7 laptop, and Bose AE 2 headphones. Most of my music files are variable bit rate mp3 with a high of 328k to a low of 128k. The audio preformance has the warmth of a tube amp with the detail and clairty of a solidstate amp. I'm really like it, highly recommend.

Pros: really good audio

Cons: none

E Rey little bit helps

Siuate from NYC on 7/17/2013

Crutchfield Customer Review (What's this?)

I packed the D1 on my summer trip and have it hooked up to a Mac Air and Bose Soundlink Bluetooth speaker. It sounds great! I was able to easily compare it with a Bluetooth and 3.5mm cable hook-up and it's quite noticeable. There is ample bass and the midrange is clearer. If you care at all about sound quality, the D1 is a pretty inexpensive way to improve your tunes.

Pros: Good build and comes with the 3.5 mm audio cable.

Cons: Have grippy or suction style feet so unit can stay in place.

Great sound and well built

Mile T from Richmond, VA on 6/18/2013

Crutchfield Customer Review (What's this?)

Great sounding and built to last for years to come. This little DAC worked wonders for me, easily powered my Bose Headphones. I will gladly recommend this to my friends.

Pros: No drivers to install, and is powered by USB, so no messing with power cords.

Cons: None

Awesome little thing

JH from upstate NY on 6/4/2013

Crutchfield Customer Review (What's this?)

This is a good unit. Its small, it provides better amplification, and you'll clearly hear the difference in the dynamic range in volume and tone. This is particularly useful if you are using full size head phones of high quality.

Pros: small, versatile, good value, great improvement over in computer amplifier

Cons: have not found any yet.

Sweet. Period!

Pros: build quality features


Its optical input is great!

dankotee from Fremont, CA on 4/29/2013

Crutchfield Customer Review (What's this?)

I would recommend this to people who are considering portable DAC, including NuForce. I ordered the open box and it came in excellent condition. No scratch, no dent, no sign of use. However, the USB cable that it came with does not work. The computer cannot detect it and I could not hear any sound. So I read their troubleshooting section and switched the cable. It worked immediately! One thing I like the most about this DAC is its optical input. I do not own a receiver, so I can't use my AKG headphone to watch movie. But now I can connect this to my TV and use my headphone to watch movie or play video games without waking up other people. The size is okay, it is pretty heavy too. But then you know the build is sturdy and a lot of "meat" is packed inside. So it is not as portable as DragonFly.

Pros: Optical input

Cons: Size is bigger than other portable DAC

This little thing is amazing. I use to always say it's crazy to spend $300.00 on a set of headphones to listen to music on your computer until I purchased the Audioengine. I for one love music,and I love how this item makes music sound great.I like jazz and old school and you can hear everything just the way its meant to sound,GREAT music just sounds great. I can listen to music all day now without disturbing others. Its not just listening to music,Its hearing the music.I would recommend this to all my friends.Great item.

Pros: Its small,It sounds great.

Cons: Could use some more power; or maybe its me.I just like BIG POWER!!!

Cleaner bass, more balanced sound

Alberto T. from Huntington Station, NY on 3/27/2013

Crutchfield Customer Review (What's this?)

I must say the reviews I had read here on Crutchfield and elsewhere were right on. The Audioengine D1 makes a big difference in listening to music from my computer. It's not earth shattering, it's subtle but definitive. I'm using the D1 paired to an Audio-Technica ATH-M50. At first listen I noticed bass did not sound boomy as it did before (not the headphone's fault), even from a poor youtube source of the Harlem Shake. Next I tried some higher quality files from iTunes... wow! Nat Cole's vocal in The Very Thought of You were more refined, instruments were a LOT more crisp and discernible. Just about anything I listened to sounded better, as if I had been listening to music through a heavy blanket. Listening to music is even more enjoyable now with the Audioengine D1! I have only used the D1 attached via the USB port, I have yet to listen to it through the optical in. But so far it's VERY good!

Pros: Better controlled bass Cleaner vocals Makes instruments more discernible


Great sound from this DAC

CMM from VT on 3/18/2013

Crutchfield Customer Review (What's this?)

I'm using the D1 with the PSB Alpha PS1 amplified speakers - and it is a great pairing (my PC is a home build, core i7-870, Win-7 64b w/ 16GB ram). Clean, accurate sound from my mp3's (I also have WAV files and itunes AAC as well). I use a belkin gold series 6 foot usb cable to connect with my computer, which works well (10 ft did not work for me). Setup was easy, once I switched to the 6ft cable. Windows easily recognizes the D1 and auto installs drivers. Without a doubt -- using a DAC w/ your computer is well worth it. Before this, I had always used the line out from either a basic sound card, or in my current build - the line out from the built in sound off of the MB (yea, I know- lame :) Using the DAC basically improves every part of the sound coming from your speakers - lows, mids and highs. I just got the PSB's (replaced bad m-audio av30's) - and I had a chance to use this DAC w/ the m-audio's for a couple days (before they choked)... and WOW -- amazing difference in the sound. Now, using the PSB's w/ this DAC - the sound is simply amazing.,.. I couldn't be happier (course, the PSB's are a few notches above the m-audio in quality :) Highly recommended.

Pros: Build quality, excellent sound. USB powered. Large volume control knob on front of unit. Good warranty.

Cons: A tad pricey... quality 10 foot USB cable to computer did not work w/ the D1 - presumably due to USB power requirement (6 foot worked fine -thankfully - since 2-3 foot was NOT going to cut it for my setup)


MURRAY IM from SAN DIEGO, CA on 3/13/2013

Crutchfield Customer Review (What's this?)

I bought this to use with my receiver. Not a good application. I could only use it with the rca out put of a single component. This is better used in a digital computer set-up.

Pros: Used on a single component like my oppo 103 player, it sounds good. The sound is almost three dimensional.

Cons: Crutchfield sales said it could be used on my receiver. So far no way.

Not Bad, for the price, a keeper for sure.

Phil W from Easton, MD on 2/28/2013

Crutchfield Customer Review (What's this?)

Good sounds, NO ground isolation so you need to be aware of you your installation requirements. Works well with other AudioEngine components. Flawless with my Laptop, Hum (ground) loop issues with my desktop PC.

Pros: Easy (up to) 96KHz/24Bit i(USB) interface for Hi-Re music playback, useful volume control, and it sounds good.

Cons: No ground isolation...which may or not be a problem for your application. Need some Velcro feet since it is soo light.


Big Al from Naperville, IL on 2/5/2013

Crutchfield Customer Review (What's this?)

I researched a lot to pick the perfect DAC/AMP for work. I have the headphones on all day and the sound from the PC just wasn't good enough. I bought better headphones that helped a little but still it was not rich and full. I talked to Derrick at Crutchfield and he recommended the Audioengine D1 over the other model I was considering. I ordered it and it arrived well-packed and quickly. Installation was a snap. Windows recognized it and installed it immediately even making it the audio output. I didn't have to do anything but plug it in and insert my headphones. When I did the sound came alive. It is rich and full and the bass is more powerful and very well defined. Most people wouldn't bother for work to do this but I am here to tell you it makes listening to music at work so enjoyable the time just flies by!

Pros: Super easy to install, great music quality, good build quality, easy to use volume control knob.

Cons: None


Ken from San Francisco on 1/12/2013

Crutchfield Customer Review (What's this?)

For three years I've had a pair of Audioengine 2's that I've been using with my iMac. Great little speakers, but when I recently got a D1 on the recommendation of reviews- wow! The difference in clarity with 256 kbps itunes files is absolutely amazing- It's as if a blanket has been lifted from the A2's. Mids and highs are MUCH crisper, and it's not even broken in yet. I listen to everything from bluegrass to EDM, and it all sounds vastly better with greater sound separation. Just don't forget to change the Midi settings for iOS per the instructions to 96 khz and 24 bits- I was disappointed until I did that.

Pros: Inexpensive, portable, crisp and bright sound, better stereo separation

Cons: No remote

So much better

LoveQualitySound from Silverlake, WA on 1/10/2013

My computer headphone jack surged and blew my Rotel. VERY COSTLY. So, I bought this to remedy that issue and avoid future service repairs. I didn't expect much of a sound improvement, but it truly is a HUGE improvement in sound quality. I have a high end Gigabyte board with Realtek HD audio on-board, which I admit I was actually satisfied with. So, when I plugged in the Audioengine D1 and heard better bass control on my Boston sub, warmer and richer tones from top to bottom, I was shocked. Seriously, very excited.

Pros: For me, I like that it's small, I like that it has RCAs... It improves sound. Plug and play--took my computer five seconds before it informed me the "device is ready to use" after plugging it in. Volume control is handy.

Cons: I'd love it if this thing had HDMI. I could see how some people would want a remote with it. I understand that for some people, the fact it's small is going to be a con. It might move around. Might need some velcro? Personally, I like that it's small.

Using the DAC between my CD player and tube amp in a stereo application. Arrived in good shape.

Pros: Seems to work well. Especially note increased clarity in the mid and high ranges. Glad I bought it.

Cons: Very small and light...moves around unless you secure it in some way. If not used with a USB port have to purchase a wall adapter for power.

Best DAC fro the money

Rick from Oley, PA on 12/9/2012

Crutchfield Customer Review (What's this?)

Seems today everyone is interested in video entertainment, and enhancements and features for that purpose. I'm sure there are still others out there, beside myself, who love music far more. I have a great audio system, including an incredible tube amplifier that my son built for me. I recently purchased the Audioengine D1 DAC so that I could stream high quality music from my computer to my system. Believe me when I tell you that words cannot describe how fantastic this setup sounds. If you love music as I do, you owe it to yourself to purchase this missing link and begin to enjoy all that the internet has to offer an audiophile.

Pros: Essentially no setup involved. The first device I ever found that is truely "plug and play". Built in high quality headphone amplifier. Extremely low cost compared to other DACs on the market. Very portable. No additional power supply required, being powered by the USB power buss.

Cons: None whatsoever.

Paired with Audioengine Speakers

Sleepy from Dallas on 10/30/2012

Crutchfield Customer Review (What's this?)

I paired these up with some Audioengine powered bookshelf speakers for casual listening in my bedroom. The source is FLAC and MP3 files off my computer. The combination has a nice warm tone and does a gorgeous job with sparse arrangements like jazz combos or singer/songwriter type stuff. It has enough punch for a little rock but I don't think it is up to a massive orchestral recording. I bought it for the simpler stuff so I am quite happy listening to Feist or Fleet Foxes on it while hanging out in the bedroom. I don't like headphones much so I can't comment on it as a straight headphone amp.

Pros: great DAC, good problem solver component


8 Time World Hit Recording Artist & D1 Fan!

Kris Allen & Southern Thunder from Nashville, TN/Charleston, W.V. on 10/10/2012

Crutchfield Customer Review (What's this?)

Let me tell you I had this D1 hooked up to my system faster than I could unwrap it from its packaging, fast and easy with instant results! Now I have to say at first I wasn't blown away when I plugged in my Sennheiser HD-600, it sounded fantastic but not overkill. However when I plugged this into my laptop controled PA I was blown away! I know my system! Well... I knew my old system, I LOVE my new system!!! I use Crown Macro Tech amps (5000i on mains, 5000i on bass) & JBL SR 4733x & 4722. I have my HP laptop going into a TC Helicon then into a Presonus mixer All connections are Monster Cable 1000's. You know I always thought this set-up was sweet but side by side after the D1...ain't no way I would want to go back without it!!! If you have a good or great system you owe it to yourself to buy one of these lil things! There was so much that was missing in the sound without it! Everything has more clarity, more alive, a richer and full sound...THIS IS ON A FLAT EQ!!! I am now buying yet another D1 for my music radio show I host (Late Night with Rob & Kris, on ghtalkradio) for my HD-600 I wear. BUY IT, YOU WILL LOVE IT!

Pros: The sound you will get!

Cons: Buy a better usb cable if you have a high end system & I wish I bought this a long time ago!

Mark from South Elgin, IL on 8/20/2012

Crutchfield Customer Review (What's this?)

I was skeptical. My only regret is that I didn't buy this a long time ago. If you listen to your PC for music you have to own this. I have been using it for about ten hours, the directions say it takes about 40 to 50 hours to "break in"...somehow I can't imagine it can sound any better than it already does!

Pros: SOUND! Incredible! Voices, instruments...amazing. Everything has a clearer, cleaner sound. Takes up very little space. Easy to install.

Cons: I spend too much time in front of my PC already, this makes me want to stay after work, kick back, relax and listen.

Brownjuan from Lenexa KS on 7/20/2012

Crutchfield Customer Review (What's this?)

Paired with my A5 speakers, the D1 provides sound with better depth, more detail, and is simple to hookup. Music simply sounds better, particularly when encoded at a high bit-rate. Build quality is excellent, very easy to use, great value for the money. I trusted Audioengine for my speakers, they have come thru again with this DAC.

Pros: Purchase value; build quality; performance.

Cons: Reveals poor quality in audio sources (but that is expected!)

Cons: none!

Ultimate Upgrade!

Errol from Silver Spring, MD on 4/14/2012

I purchased the D1 to use primarily as a headphone amp. My PC could not drive my Grado SR80s. I knew the Grados were not the problem as the SR80s sound great when connected to my stereo amp. When I hooked up the D1 to my computer (Shuttle XPC w/ Win7) it immediately recognized the device and installed the drivers. I was up and running in under 5 minutes and wow. I had no idea how good the music from my PC could sound. The D1 provides a crystal clear signal. Not only is the power boosted but I am no longer getting any residual hum in the background between tracks, just a clear audio signal. An added bonus of the D1 is that it has breathed new life into my old Altec Lansing ATP3 speakers. Before I hooked them up to the D1 was getting a lot of buzz and hum when I turned them up. The D1 has fixed that problem and saved me from buying new speakers (at least delayed the purchase). The D1s crystal clear signal has the speakers bumping like new. If you want decent sound from music on your computer the D1 is a must have accessory. Reference Music: - Blues Traveler - Blues Traveler - Trombone Shorty - Backatown - Tool - 10,000 Days - Dr. John - Locked Down - Dr. Dre - The Chronic - Rodrigo y Gabriela - 11:11 - Budos Band - Budos Band Note: I used a 3.5mm Stereo Female to 2RCA Male cable I picked up from another retailer to connect the Altec Lansing speakers to the D1

Pros: - Easy setup - Easy to use - Crystal clear signal - Quality build - Sounds great out of the box. Should improve with use.

Cons: I am not getting enough sleep, because I am staying up late listening to my music collection.

D1 DAC is #1

David R. from York, PA on 4/13/2012

Crutchfield Customer Review (What's this?)

bought this little device with really no expectations of it making a huge impact on my computer audio system. was I ever wrong. I made small incremental changes to my system. first it was the new laptop (HP Entertainment), then new speakers (M-Audio AV-40), then upgraded speaker cable (Monster), then the D1 DAC. once the D1 DAC and Audioquest USB cable were installed, I noticed a significant inprovement in overall clarity, detail and tighter bass. the speakers were now free of the HP sound card and able to really open up. these speakers now sound so much larger than they actually are and play much louder. so far I am very happy with the purchase right out of the box. no break in needed. have not tried with headphones yet.

Pros: size of device improved clarity and detail in internet music ready to go out of the box easy installation

Cons: volumne knob is sensitive

The other devices in this category all appear to require a separate USB driver download from the manufacturer website. [ John  May 20, 2018 ]

The Audioengine D1 DAC has a full scale output of 2V RMS. So It is possible to increase the power to your AUX input.. Please note that this DAC has 1 USB power/audio input and 1 spdif audio input. Connecting this DAC to your phone through USB audio is possible. You will definitely need an OTG cable for this to work. Android or iOS depending on the kind of phone that you have. But not all phones are compatible with this feature and may require purchase of an app. Also connecteding this DAC to your phone powered through USB can cause your phones battery to drain faster. Hope this helps. [ Basshead 1990  Mar 31, 2018 ]
I don't think so. This is a digital to analog converter. your phone out is already analog. Also, you would need a power source. It came with an AC adaptor, but in your truck, you would need DC to DC. It works great to connect my laptop to my stereo receiver. [ James V.  Apr 02, 2018 ]
The input into the DAC is USB, designed to connect to a computer. It's unlikely the stereo in your truck has a USB aux. [ Jeffrey  Apr 01, 2018 ]
It might a little in volume, but most of the benefit would be in sound quality. I am using this as a pure headphone amp and using the same headphones get about the same volume straight from my phone as using the amp. The biggest difference is in the sound quality, especially on the low end, but overall fullness and clarity also. Saves on battery life also. If it's just a matter of volume, you may check to see if your phone actually has two volume settings: one from the app your using, and then the phone volume itself. Hope that helps. [ Richard  Mar 31, 2018 ]
Toslink optical output works fine for me when connected to a bluesound vault so it should be fine with a CD player. Also a plus that it's a headphone amp. [ Peter  Mar 08, 2018 ]
The Audioengine converts the digital Toslink signal from my television very adequately into an analog output through good old RCA stereo cable connectors. The sound is rich and clean. It should work fine hooking into your (I'm assuming) analog amp and going through your speakers. But if the CD player is equipped with direct RCA audio outputs, it doesn't seem as if converting a Toslink digital signal from the CD player is going to be any better than just hooking up directly with RCA cables to the amp (and to the speakers attached to it.). Though who knows... maybe the converted-to-analog signal via Toslink will end up sounding better than the direct analog signal through the CD's RCA outputs. Nice thing about buying from this source is that returns are straightforward, so if it ends up not working out as you hope for, return it! [ Richard  Mar 08, 2018 ]
I had a problem with running Spotify from my Sumsung TV trying to run toslink from TV to dac to receiver. I would loose connectivity after about an hour. I finally went from lap top with USB to Dac to receiver. The dac works fine and I never figured out what the problem was. [ Fred  Mar 08, 2018 ]
I have not tried the optical input, but there is one on the back. This should be ok for a stereo type amplifier. As long as your are not trying to output a home theater type surround sound output, which can go over the ToS link, The Audio Engine manufacturer's web site states that it can take an optical input. [ Jared  Mar 08, 2018 ]
I use it on my pc it's connected to my d4z and a headphone amp I use the rcaz I don't know about optical sorry [ Chad  Feb 28, 2018 ]
As long as your cd player is set to pcm 2.0 a standard toslink connection will work flawlessly.This is an amazing and versatile entry-level dac. Highly recommended at its price point. Please note that the Audioengine D1 comes with a power/audio usb cable and still requires a usb port to receive power. In your case, If your cd player has one you can simply plug it in there. If not you will need a usb power brick rated at least 5v dc 1amp output. Sold separately. (Any usb phone charger will work as long as its rated no less than 1amp) [ Basshead 1990  Feb 28, 2018 ]
Performace is very poor..sound quallity very poor..don't buy this if you did send it back..not even worth 10 dollars..... [ Glen  Feb 28, 2018 ]
Not directly. The Audioengine D1 is a line source digital to analog converter. It will also power headphones. The D1 will take digital source via optical or USB from your computer and has one RCA Output. I connected this as an input to my preamp. This line RCA output (left and right) would need a powered set of speakers if you don't use line input to preamp or receiver. [ RICK  May 03, 2017 ]
The D1 only has a left and right unbalanced RCA output to be connected either to an external amp or powered pair of speakers (L&R). To add multiple speakers would require a splitter to send the signal to a multichannel amp or additional powered speakers. That splitter, depending on type, may degrade the signal sent by the D1 resulting in loss of signal and distortion. [ Patrick  May 03, 2017 ]
This isn't an amp so you can't hook up just speakers to it (just headphones yes, Speakers without an amp no). It's a Digital to Analog converter that goes in between your Digital source and Amp to improve your sound quality. It has Left and Right RCA outputs that you connect to your Amp, that then powers your speakers. You can run however run as many speakers as you want / your amp will handle but that is a separate part of your sound system from this DAC [ J  May 03, 2017 ]
Thanks for your question. Yes it does, it comes with a 24" USB cable (USB Type-A on one end and USB Type-B on the other). Hope that helps. [ Kenny  Jul 19, 2016 ]  Staff

I only have a PC and the D1 works fine, Great product. Ray [ RAYMOND  Sep 18, 2015 ]
Jeff- As far as I know I have had no negative issues with the Audioengine D1 relative to compatibility with Yosemite. The unit does a terrific job of bringing digital audio to life for me. I must say that if I leave it plugged into the USB port for several days I may find that there are some strange sounds or silences that may or may not occur in the middle of a musical passage. If I unplug the USB and reconnect, it goes away instantly and does not happen again unless I leave it plugged in for several more days. Is this a Yosemite issue? No idea. good luck, Dennis [ Dennis  Sep 16, 2015 ]
It works on my iMac, which has Yosemite installed on it. Check system settings, under sound, and output. Also, check Audio Midi Setup. [ Adam  Sep 16, 2015 ]
Again jeremy It is easy to install using the sound app in your computer. Easy instructions provided. [ RAYMOND  Apr 15, 2015 ]

Sorry I've got mine connected to my tv to older system Bose [ THOMAS  Apr 14, 2015 ]
I use a Mac but this should work just fine with a PC running Windows. You just need to make sure that you have and output set to use the proper port. I really like this unit. It is very simple and sounds great! [ ERNEST  Apr 14, 2015 ]
If it accepts RCA input, then yes. [ Peter  Nov 22, 2014 ]
I do not understand enough about the significance of PCI circuitry to answer the question. If you are referring to the high end Bryston components it seems to me that the Audioengine D1 DAC is not as high end as the Bryston and you are not doing justice to the sensitivity of the Bryston component. [ HONG  Nov 22, 2014 ]
This unit replaces any sound card you may have in your computer system. It connects to your PC using a USB port. The outputs of the DAC can be connected to your stereo either through RCA plugs or an optical connection. There is only the USB port for input because it replaces your sound processors so needs direct access to the digital content. [ DAVID  Nov 22, 2014 ]
Unfortunatelly the D1 only has USB and optical SPDIF inputs, and can't be connected directly to a PCI slot in a computer. Any USB port on your computer would provide power/data to the D1. However, if you have optical SPDIF out on your motherboard, it should produce even cleaner output for your stereo system. You would just need to feed 5V to its USB port via any USB charger. I use an extra smartphone charger I had laying around, [ Alberto  Nov 22, 2014 ]
I do not know! [ MURRAY  Nov 22, 2014 ]
Hi Susan, I'm not sure I could technically answer your question since I do use headphones with this DAC, mainly cutting sound for videos and I did find it more than adequate - I also use Sennheiser, though HD280 model - but I mainly got it too listen to my music directly from computer since I ripped my thousands of CD and even some vinyls into iTunes so they are all handy, and I paired Audioengine D1 with their speakers that are right next to my screens - they sound great, warm and with good bass, but not overpowering - and I also connected it to my main Harman Kardon amp and I have to tell you that it sounds great, I honestly sometimes forget that these are only mp3 files playing out of my computer and not the full CD audio quality files. I recommend the gizmo, it's worth it. Hope this helps. [ DEJAN  Nov 11, 2014 ]
I believe so..........! [ MARK A  Nov 11, 2014 ]
I can't speak to those particular headphones. I use mine with Grado SR80 which are 32 ohms. I primarily use the D1 as input to Audioengine A2 speakers. I am very pleased with the results and get plenty of volume. [ DANIEL  Nov 11, 2014 ]
It should provide enough power for those headphones, but may leave you with an uncomfortable lack of overhead knowing that youre maxing out the volume. According to audioengine, its good enough for headphones up to 300 ohms, but the signal to noise ratio will determine how much volume you get out of them. I would personally recommend a standalone amp such as one of the budget offerings from Schiit audio. Good luck and enjoy [ PABLO  Nov 11, 2014 ]
Yes. plugging in headphones will mute the speakers [ DANIEL  Jan 03, 2014 ]
Jeff, The answer is yes. When you use the headphone jack the rear analog outputs are muted. I am not sure about the digital outs. [ STEVEN  Jan 03, 2014 ]
Yes, Although I still check about ten times a day just to be safe. The rca outputs are disabled when headphones are plugged in. [ BRIAN  Jan 02, 2014 ]
Yes, the speakers are auto muted when you plug in headphones into the D1. [ NORMAN J  Jan 01, 2014 ]
Yes with the headphones plugged in and the audio engine D1 powered the speakers are muted. The headphones sound great as well. [ GORDON  Jan 01, 2014 ]
Yes they are. [ Peter  Jan 01, 2014 ]
yes [ cmm373  Jan 01, 2014 ]
The answer is yes [ BRIAN M  Jan 01, 2014 ]
I can't say the speakers get muted, but when I forget to unplug my headphones, I have to turn the volume way up to get any sound from the speakers. [ michael  Jan 01, 2014 ]
Jeff r. Yes, the speakers I have connected are muted when I plug in my headphones. [ LARRY  Jan 01, 2014 ]
I don't own any headphones...sorry~ [ TODD  Jan 01, 2014 ]
Yes, it does. The setup manual states that the analog output will be muted also. [ DAVID  Jan 01, 2014 ]
Joe, Not has an optical output so it should work, cannot say for sure. I'm hooked up to my home office computer. Dan [ DAN  Jan 03, 2014 ]
I have not even tried the optical input. I got it mostly for the USB part to be able to listen to music on the computer. However, below is a quote directly from the owners manual which may be useful to you: The D1 can process digital audio at any bit depth up to 24 bits, and any sample rate up to 192KHz. The D1 USB input can accept a USB audio stream from your computer or other USB source device. The D1 optical input can accept optical (PCM stereo) streams from any optical (TOSLINK) source, such as TVs, Apple TV®, DVD/BluRay players, CD players, etc. Note: optical sources must be set to PCM Stereo. [ NICK  Jan 01, 2014 ]
I don't know if it will work with a DVD player, but it surely a nice set of headphones sound GREAT. I use it as an headphone amplifier on when listening to music on laptop. [ RORY P  Dec 31, 2013 ]
Joseph, I've never connected it to a DVD Blu-ray player, but I have used it with the optical out on my TV, and it worked just fine. I'm sure it would work with your Blu-ray. I love the D1, btw...I use it daily with my computer. Matt [ MATT  Dec 31, 2013 ]
Yes, we operate the unit that way with our Sony Blue-ray DVD player BDP-S580. [ ERIC L  Dec 31, 2013 ]
Also, the unit is powered through the USB port. I used my iPhone charger with success. If your TV has a powered USB port, you can hook into that as well with the cord supplied with the D1. [ CARL M  Dec 31, 2013 ]
Yes, but it will depend on the media. If the DVD is playing in a surround mode like 5.1, you will not have sound. Can you set the preference to 2 channel stereo? [ CARL M  Dec 31, 2013 ]
Joe, I can't definitively say. I do have the product and have been quite happy with it. I have it connected to my computer via standard RJ-45 network cable. I have it further connected to a pair of Emotiva 4 desktop monitors. From looking at your Blu-Ray player pics online, it appears you have this connector available. I believe it should work. What I would advise it to email Audioengine with the question. I also believe you can order the device and try with the understanding that you can return it. If I recall Crutchfield allows a return on the product within 30 days. [ brock275  Dec 31, 2013 ]
It has an optical input so I assume it should. [ HAROLD  Dec 30, 2013 ]
Mine works perfectly with the optical out from my computer. You will still need to power it through the USB port. I use a USB cable and 120 V USB charger from my old iPhone. [ FRED N  Dec 30, 2013 ]
Hi Joe, yes it will, as long as your Blueray player,s optical output is set to PCMas this what it will see(Audioengine D-1). I have mine connected to a Technnics A-10 DVD Audio player and my computer, it works great!.The Priority function for the D-1,s inputs is if you have your computer USB pluged in it will not be useable, until the DVD player is turned Off. I hope this helps you..Ron P [ Ronald  Dec 30, 2013 ]
I agree with Richard W (above). The D1 can read stereo input only. 5.1 or 7.1 is a no-go. [ Robert  Dec 30, 2013 ]
I used optical out (with miniTosLink cable) from Apple Airport Express to the D1. Worked fine. [ Robert  Dec 30, 2013 ]
I can't say for sure, but I'm guessing it will -- this is assuming you configure your blu ray to transmit a stereo signal that is compatible with the D1's input (24/96 is the max I believe). If your blu ray is transmitting 5.1 or 7.1, my guess is that the D1 won't be able to decode it. Your best bet is to email audioengine to be sure. [ RICHARD  Dec 30, 2013 ]
