This versatility makes the A-S801 an excellent choice for anyone looking to design a fantastic two-channel rig with digital and analog capabilities.

Digital connections with high-resolution playback

When you connect your computer to the A-S801's USB input, your digital tunes will benefit greatly from this amp's high-quality ESS SABRE digital-to-analog converter (DAC). It converts your digital files into analog signals, preserving all of their detail, for accurate sound. This DAC can also handle high-resolution music, including DSD files and 24-bit/192kHz PCM files. There are also optical and coaxial digital inputs — connect a TV or Blu-ray player to these inputs, and enjoy movie sound through your stereo speakers.

Great sound from any source

With digital or analog signals, this amp delivers sound that's dynamic and clear. Thanks to anti-resonance construction, a symmetrical circuit layout, and high-quality components, the A-S801 keeps distortion levels incredibly low for superb sound quality. If you need to make some adjustments as you listen, there are front-panel tone controls for bass and treble. There's also a loudness control, for bringing out more detail and depth while listening at low volume. Or, bypass these controls with Pure Direct mode, which eliminates signal degradation as your music travels a more direct circuit path. For listening to CDs, engage CD Direct Amplification — it matches the input levels of the source with the amp to further minimize noise introduced at the amplification stage.

Product Research



"Natural Sound" Concept: Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for HiFi components. Yamaha's A-S801 integrated amplifier takes advantage of this rich experience and high technological expertise. Based on the concept of "Natural Sound", for reproducing all music as it really sounds, and built with scrupulous care from circuit design to basic sound production, the A-S801 reproduces high sound quality and musically rich sound.

Proprietary Yamaha Technologies: The Yamaha A-S801 integrated amplifier employs proprietary Yamaha technologies for optimum performance and sound reproductions.

  • ToP-ART Design: When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha's amplifier design technology called "ToP-ART" features an I/O (input to output) Direct Symmetrical Design, with left and right channels organized in a straight, symmetrical layout for highest signal purity.
  • High-Strength Chassis: In order to effectively dampen the vibrations that have adverse effects on sound quality, the A-S801 chassis has a double bottom design with a 1mm iron plate.  A solid center bar further enhances high rigidity and dampens vibrations.
  • ART (Anti-Resonance and Tough): In addition, the power transformer and heat sinks in the power amp section are supported by an extremely strong and stable ART (Anti-Resonance and Tough) base.

High Current Amplifier: The Yamaha A-S801 features a dynamic, high current stereo amplifier with low impedance drive capability. The amp is rated at 100 watts x 2-channels, measured from 20-20 kHz into 8 with 0.019% THD (120 watts x 2-channels, measured from 20-20 kHz into 6 with 0.038% THD).

ESS Sabre 32-Bit DAC: After careful listening evaluations, Yamaha selected the 32-bit, two-channel SABRE Premier Audio DAC from ESS Technology, Inc. Most notable is its high precision processing power of 32-bit audio along with the ability to handle large amounts of audio data with full PCM 384 kHz and native DSD 5.6 MHz. Since the built-in D/A converter generates its own master clock, an original jitter elimination function is also included, permitting D/A conversion with an extremely low impact of clock jitter. Moreover, a two-channel D/A converter is housed inside the chip which applies a double differential operation. The result is exceptional high performance and high quality signal output with a superior signal to noise ratio.

High Quality Parts: Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminum-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.

CD Direct Amplification + Pure Direct Mode: With a straight connection to the CD input, CD Direct Amplification maximizes the CD source's signal-to-noise ratio. Additionally, engaging the Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp, the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.

Optional Bluetooth Adapter: You can wirelessly stream music from a Bluetooth-compatible device, using the optional YBA-11 Bluetooth Wireless Adapter. The adapter features aptX audio decoding for optimum sound quality. The adapter connects to the A-S801 via a coaxial digital cable and USB power cord, both supplied with the adapter.


Gold-Plated Terminals: The Yamaha A-S801 has gold-plated terminals for all of its inputs and outputs. These gold-plated terminals ensure a high quality connection that prevents signal loss.

USB (Type-B) Port: The USB DAC function supports native DSD (2.8 MHz and 5.6 MHz) and PCM (384kHz/32-bit*) resolutions. This function allows for a direct connection to Windows PCs and Mac computers which opens the door to play back of the highest resolution audio content offered today. The Yamaha-developed USB device controller has its own master clock that eliminates PC jitter. The driver is a low loss, high throughput ASIO 2.3 Yamaha Steinberg USB driver. During playback, indicators on the front-panel clearly show which sampling frequencies are currently being used. The amplifier's USB connection supports the following operating systems:

  • Windows: 7 (32-/64-bit), 8 (32-/64-bit), and 8.1 (32-/64-bit); a Yamaha Steinberg USB Driver must be installed on your PC (for 32-bit / for 64-bit).
  • Mac: OS X 10.6.8, 10.7.x, 10.8.x, and 10.9.x;  this Yamaha Steinberg USB Driver must be installed on your computer.
Note: *A compatible Windows PC will support up to 32-bit audio. A compatible Mac computer will only support up to 24-bit audio.

Analog & Digital Inputs: The Yamaha A-S801 integrated amplifier offers analog & digital inputs for connection of a variety of home audio components.

  • RCA + Phono: The Yamaha integrated amplifier is equipped with six analog stereo (RCA) inputs for connecting external analog audio sources, including a turntable. The Phono input can be used to connect a turntable with an MM phono cartridge to play vinyl records. The unit's Phono input also features a ground terminal.
  • Optical & Coaxial Digital Inputs: The A-S801 is equipped with both optical (toslink) and coaxial (RCA) digital audio inputs. The optical and coaxial inputs will accept 2ch PCM (not Dolby Digital/DTS). The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your entertainment sources, from sports and other programs to movies and concerts.

Recording Outputs: There are also two pair of RCA outputs for recording audio through the amplifier to recording device.

A & B Speaker Terminals: The Yamaha integrated amplifier features binding post terminals for its A & B speaker outputs. You can use the A & B speaker outputs to power two pair of speakers, or bi-wire a single pair of compatible speakers. The terminals are not 5-way binding posts because a plastic collar prevents their use with spade lugs and they are too far apart for dual banana plugs.

Sub Output: A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality

Headphone Output: The A-S801 integrated amplifier is equipped with a front-panel 1/4" headphone output for connecting a pair of headphones (sold separately). The headphone output and speaker outputs will work simultaneously; you will need to rotate the speaker selector switch on the front-panel to the Off position to turn off the sound from your connected speakers.


Sophisticated Front-Panel Design: With a beautifully simple and unique design inherited directly from Yamaha's HiFi audio components, this amplifier also boast an easy-to-operate button layout. The aluminum front-panel has a richly textured silver hairline finish. The control knobs are also of the same luxurious construction as used on Yamaha's top-end models. The rotary encoder makes it quick and easy to select input sources. The luxury hairline finish material offers a nice tactile feeling. LEDs clearly show which source is selected, so you can easily switch sources even in a dark room.

Simple Remote Control: The clean, simple design of the remote control provides easy-to-understand one-hand operation. The easy-to-use design makes it simple to adjust song volume and order. The remote has a sophisticated looking hairline finish that matches the design of the amplifiers. You can also use the remote to control a Yamaha CD/SACD player.

Variable Loudness Control: The A-S801 also feature a new analog loudness control on the front-panel that uses electronic volume for higher sound quality, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high- frequency sounds, providing full tonal range at any volume level; compensating for the natural loss in the human ear of high and low frequencies at soft levels.

Tone Controls: The integrated amplifier features independent bass (20 Hz) and treble (20 kHz) controls so you can increase or decrease the low and high frequency response (+/-10dB). You can also adjust the output balance of the left and right speakers.

Impedance Switch: The integrated amplifier features a rear-panel impedance switch to match the impedance level of the speakers connected. Choose High or Low:

  • High: Select High if using one set (A or B) of speakers with impedance of 6-ohm or higher; when bi-wiring the impedance of the speaker must also be 6-ohms or higher.
  • Low: Select Low if using one set (A or B) of speakers with the impedance of 4-ohm to 6-ohm; if using two sets (A and B) of speakers simultaneously, the impedance of each speaker must be at least 8-ohms; when bi-wiring the impedance of the speaker must also be 4-ohms to 6-ohms.

Auto Power Standby: The amplifier has a power management function that detects when it hasn't been used for a long time (about 8 hours) even though the power is on, and automatically shifts it into standby mode. So even if you forget to turn it off, power consumption will be minimized.

Features : Play DSD + bi-wire speakers [ YU-SUAN  Nov 28, 2016 ]
I chose this because of its clean look, and versatility of inputs and outputs. I will connect a digital recorder, a reel to reel player/recorder as well as a turntable and CD player. With this amplifier you even get to play PCM and DSD files directly from your computer. I absolutely love the sound from my older restored Yamaha C60/M60 but it's time to move on into the digital world. Compared to other brands, the Yamaha A-S801 offers tremendous value, I thought. [ Michael  Aug 24, 2016 ]
Great simple 2 channel amp with the added perk of DSD DAC! [ Daniel  Jun 27, 2016 ]

25 questions already asked

Hi, the speakers are silenced when one plugs in headphones. As far as I can tell one cant play 'phones with the speakers playing so the sub is quiet. Hope this helps, I love my A-S801! [ David J.  Jul 24, 2018 ]
Hi Ryan, To the best of my knowledge: no. The speaker and headphone outputs are independent, switchable on he front panel. In other words ext speakers and headphones may be run together. Though not sure why you'd want to... It's a great unit. Really pleased with it. Cheers, Norm [ Norman  Jul 23, 2018 ]
I've used my phone to connect with this amp. Double RCA in back; into a single plug into your phone jack. I've listened to Amazon music and Sirius radio this way (through the phone apps.). As for the first part of your question, you might want to just consider a media streamer, hooked up to this amp. I have a Cambridge media streamer, and it picks up (through Wi-Fi) music that is physically located in files on my computer. The quality of the music from the media streamer is good. I've never tried to pick up you-tube from the computer with the phone, or the media streamer. [ Jeffery  May 11, 2018 ]
Yes I use rocket fish Bluetooth receiver works greay [ Michael  May 11, 2018 ]
I only have experience with the A-S801 Black, but it drives two different sizes of KIipsch tower speakers perfectly for both chamber opera with clear, delicate high soprano voices AND the huge sound track for Game of Thrones. [ Susan  Nov 22, 2017 ]
I seem to recall there was a difference - what about the DAC chip? That can make all the difference - I have the 801 and it's a simple but great sound producing music amp!! [ vijay  Nov 22, 2017 ]
The DACs sound different. I think the as701 has a more smooth sound. The as801 has better dynamics and is little more exciting to listen to. Both are good though, depends what you like. The as801 also has a USB input so you can run high res audio - DSD etc... [ Benjamin  Nov 22, 2017 ]
Can't say about 2 ohms, but I am pushing a pair of Martin Logan Motion60's at 4 ohms with no issues - though it is in an open cabinet. I have been very pleasantly surprised with this amp. Simple, elegant, powerful, and easy to use. [ William  Mar 14, 2017 ]
I would recomend connecting with USB. It will sound better than other connections. Run a USB cable from the Mac mini's USB port to the USB in port on the back of the S-A801. In the mini, open the midi set up select the Yamaha USB ,then got to preferencs >speakers and select Yamaha and you should ready to go. The S-A801 manual has all of this too. Happy Listening [ Jeffrey  Mar 18, 2017 ]
The sound quality is the same. either port can handle Hi_rez files. I've read there can be more issues with USB out than the toslink which is out of the headphone jack. I use the toslink on my iMac and hit sounds superb going into my A-s801. I've used both and neither mattered so I use the toslink to free up a USB port on my iMac. IT's a great amp. You won't regret buying it. It's popular in the audiophile circles I run in if you don't want to spend a fortune on an amp. [ Peter  Mar 12, 2017 ]
I didn't compare both alternatives, but the "classical" and probably most straightforward way to connect both devices is via Toslink and a Mini Toslink Adapter for the Mac Mini headphone jack. A third alternative would be to connect both devices via an Apple TV and AirPlay: The Mac Mini would be connected to the Apple TV via AirPlay, and the Apple TV is connected to the Yamaha 801 via Toslink optical cable. The advantage of this connection method is that you can easily integrate any other Apple device as a music player, e.g. an iPhone, iPod or iPad. [ Robert  Mar 11, 2017 ]
Not using either - but the rca audio videos are fine - optical or USB could only be better!! [ vijay  Mar 11, 2017 ]
Haven't tried the optical, but the USB works great with my MacBook Pro as the music server.. bw [ Vickie  Mar 11, 2017 ]
Yes it is. I picked it because a class D amp generates very little heat, and I had to put the amp inside of an enclosed cabinet. I have had it for a year, and I love it. The sound is as good as my class A/B NAD amp that generates so much heat it will cut itself off unless it is in the open. [ William B.  Feb 11, 2017 ]
Hey Chuck , the A-S801 literature does not say but it acts and sounds like an A/B under normal circumstances. I have been running this amp for about ten months and the speakers I have currently are very efficient and present an 8 ohm load and it sounds very good. The A-S801 has some very nice features also. If it's class D I would be surprised, however if you are running speakers with a 4 ohm load am not sure how good it would be. For the money it's a great amp with great features and I would bet it's not class D [ JOEL  Feb 11, 2017 ]
Thanks for your question. For pricing information or possible price matches please reach out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question. [ Kenny  Dec 19, 2016 ]  Staff
No. It offers outputs for recording but not for use as a pre-amp. You'll find our selection of stereo pre-amps on the website here: I hope that helps! [ Ryan  Jan 01, 2016 ]  Staff
I forwarded your question to an Advisor and they responded with the following: The USB input on the Yamaha is not rated for an Apple device, so you wouldn't be able to connect an iPod through the USB. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Apr 01, 2015 ]  Staff
U need atleast 75 to 100 Rms speakers with the 801 at 4 ohms [ vijay  Nov 22, 2017 ]
I believe the difference between 4 and 8 ohm output is pretty universal, but i could be wrong... Most companies just list the 8 ohm rating. I don't know the 4 ohm rating either, but I was comparing this amp to a similar peachtree amp which does list both 4 and 8 ohm ratings and the 4 is about 60% stronger. I think you'll be fine with this amp. My speakers are also 4ohm and the sound/power is fantastic. Hope this helps! [ John  Feb 05, 2015 ]
The sound from a turntable is as natural as hearing it live, but there can be noise along with left/right channel audio alignment issue from the needle touching the album. Digital audio does not have that noise and almost always does not have the alignment issue. However, where it is digital, it does not have a smooth sound wave to it and a handful of people have been able to hear that! I don't' think there is a clear winner for overall sound. Now, we do have advisors that can discuss your preferences and things to give you a personal recommendation on this. You can reach on by calling 1-800-324-9695. My Bio: [ Paul  Dec 31, 2017 ]  Staff
Edward Sorry I can't answer your question because as of yet I have not used the DAC interface as a source to compare with the analog output of the turntable. However I am in the process of setting up a digital library and intend to do so fairly soon. I can note at this time the Yamaha S801 is a fine integrated amp and to the extent I have used its non DAC features, including using a turntable as a source, the Yamaha S801far exceeded my expectations and am very happy with its performance. Steve [ Stephen  Dec 28, 2017 ]
HDCD simply increases the 16Bit information of standard CDs to 20 bits. The ESS Sabre DAC built-into the Yamaha supports up to 32 Bit content so, you'll be good to go, yes. I hope that helps. My Bio: [ Ryan  Aug 12, 2017 ]  Staff
Yes, I connect it to my Window 10 PC through USB, and play HiRes music files. [ YU-SUAN  Jul 14, 2017 ]
I have these components and they sound amazing. I dig this system the most, Man. [ Van  Dec 30, 2016 ]
With a true 90 watts of rms power per channel in the A-S801, it should be able to power your Polk LSI M703 speakers just fine. The polka are fairly efficient at 88 she sensitivity . You will find they will play quite loud with 10 to 20 watts. Unless ofcourse you are a head banger, then 200 watts per channel won't be enough. [ Jeffrey  Dec 30, 2016 ]
I think they are a great match. This amp has a lot of clean neutral power. Crisp high's and very clean snappy bass, in a good way. The first thing that jumped out when I hooked up this amp was how well it controlled the bass. Strongly recommend this amp. The crutchfield advisor at the time recommended this model over a few higher priced integrated amps they sell. [ Peter  Dec 30, 2016 ]
I also ordered the Yamaha YBA-11 Bluetooth adapter. I stream Pandora all the time from my phone by the Bluetooth connection [ Scott  Oct 05, 2016 ]
I suppose your assumption is correct. I can't make a statement on the sound quality of the R-S700, but I don't think the weaker connection options of the A-S801 (with regards to your specific needs) will be overcompensated by it's superior overall architecture. I purchased the A-S801 just because of one unique and outstanding feature: it's high quality SABRE digital audio converter (DAC). In combination with it's optical line in, I can stream digital sound right into the A-S801, without pre-converting it to analog signal in a device with a weaker DAC (e. g., like embedded in Apple's lightning docking station). The conversion is performed by the A-S801's DAC - the resulting sound is simply great (as long as the speakers are also high quality). [ Robert  Sep 30, 2016 ]
I haven't used it ,but I believe it is to plug your computer into, to play your audio files. [ charles  Aug 09, 2016 ]
you can connect it to a pc and play music files [ ROBERT  Aug 06, 2016 ]
Hi Joshua, This is how you use your amplifier's Digital Analog Converter (DAC) to play digital music from your computer and convert it to analog. There is an explanation in the owners manual. You do need a USB B male end and USC C male end to plug into your computer just like a printer. You need to download software onto your computer and install. This is explained in the owners manual, and was very easy. This is the reason I bought this amplifier as it had this DAC capability. Hope this was helpful. Mark [ Mark R.  Aug 06, 2016 ]
Although I haven't used mine, as I understand it, it is for the ability to connect a computer (laptop for example) to the receiver to play back music files on the computer via a USB cable. Also, as I understand it, you cannot just hook up an MP3 player to do this. It must be an actual computer for some reason. Hope this helps. [ ROBERT  Aug 06, 2016 ]
It's common for DAC's to use this type of connection. AudioQuest makes good ones for this application. [ James  Aug 05, 2016 ]
Best way to buy the Yamaha Bluetooth dongle (Yamaha YBA-11) and connect using bluetooth [ Jung  Aug 11, 2016 ]
Plug it into the USB port! [ Van  Aug 06, 2016 ]
Yamaha has an optional Bluetooth receiver that you can use to stream audio from your iPhone and iPad . For the MacBook connect a USB cable between your MacBooks USB A port to the AS 801's USB B port on the back. Set up the audio connection in the midi and speaker function in the MacBooks preferences. You should be able to stream songs directly from your iTunes library. Oh, make sure iTunes is in session before setting the audio functions. Happy streaming [ Jeffrey  Aug 06, 2016 ]
Use the USB port. Simply connect a AB usb cable from your computer to the AS 801. [ Tony  Aug 06, 2016 ]
Buy Apple TV (3rd generation is fine, 4th not needed), connect the Apple TV to the Yamaha AS 801 via the digital optical connector (Toslink), and stream your music from iPad, iPhone, MacBook to the Apple TV. Set the input selector of the Yamaha AS 801 to "Optical" - that's it. [ Robert  Aug 06, 2016 ]
It has a DAC. All you need is a usb cable (like one that you would use with a printer) and it connects right to the Mac. [ ROBERT  Aug 06, 2016 ]
Joshua, You will need to add a Sonos as a component (and I recommend also getting a Sonos Boost) and then you will be good to go! [ Andrew  Aug 05, 2016 ]
The device has no local storage. It is not an external drive/ DAC combo, but rather a receiver with an excellent onboard DAC and the ability to connect to a computer via a USB A- USB B cable. To do this, you simply run the cable from a USB port on your computer (Audirvana Plus has very good instructions for choosing the best USB port for this) to the USB input on the back of the receiver (see photos on Crutchfield's page for the item). It has a Total Harmonic Distortion (THD) rating of less than 2%, which is lower than most external DACs and receivers in this price range or higher and sounds phenomenal. I couldn't recommend it more highly. [ James  Aug 05, 2016 ]
I'm assuming it would be.. The Sabre DAC is great, I don't see why they would put a separate one in for optical or coaxial. I have this system myself and use the DAC on a daily basis and it has been fantastic. I highly recommend it. [ ROBERT  Jun 26, 2016 ]
That would be my guess. It's hard to imagine they would use more than one DAC in a stereo receiver, especially when they tout the inclusion of the Sabre so proudly. The receiver sounds phenomenal, regardless, and it's hard to beat the low THD level, for the price. That said, if you want to know for sure, I would simply call Yamaha. They have very friendly, knowledgable support staff. [ James  Jun 26, 2016 ]
Yes, there is one DAC for all the digital inputs. [ Jeffrey  Jun 26, 2016 ]
I have not tried this, but I don't see why It wouldn't. I am using the optical port for my CD player. [ JAY  Dec 13, 2015 ]
I haven't tried this yet. [ Allen  Dec 13, 2015 ]
Yes,the A-S801 will decode 2 channel PCM digital audio from this player. Make sure the audio output from the WD TV is set for 2 channel PCM. The A-S801 will not decode and play Dolby digital bit stream surround sound audio. [ Jeffrey  Dec 12, 2015 ]
Sorry I can't answer. I am using the unit for analog music. [ FRANCISCO  Nov 02, 2015 ]
You could attach an iPod (Lightning) Dock to one of the line in connector pairs of the A-S801. Disadvantage of this solution: The sound is remarkably worse than that of a pure digital transmission, as it seems to me that the DAC embedded in the Apple iPod Dock doesn't have a high-end digital-to-analogue converter chip inside. If you own a newer "lightning" iPod, I don't see any alternative to streaming, because any previously manufactured high-end (hi-fi) DACs are not available with a lightning connector. Therefore, I decided to purchase an Apple TV when I purchased the Yamaha A-S801 Silver. The Apple TV is directly attached to to the optical input connector of the Yamaha A-S801. Music from the iPod is streamed to the AppleTV via AirPlay, which means the sound is transmitted to the AppleTV and from the AppleTV to the Yamaha amplifier purely digital, without any conversion. The final conversion happens inside the A-S801 which has a very good DAC chip inside. I found the sound to betty very good if I use the iPod/AppleTV/Yamaha combination in this way. [ Robert  Nov 02, 2015 ]
I have no idea, i simply use my YAMAHA s 800 to lesson to cd or tape with great speakers. The sound quality is delightful for me !!! ( i'm definitely an old fashion music lover ) [ DANIEL E  Nov 01, 2015 ]
Sure will, excellent amp. [ Earl  Aug 29, 2015 ]
Absolutely. [ John  Aug 28, 2015 ]
no problem... two sets at the same time if you choose a + b ... I did a lot of research on 2 channel stereos before I bought this one... specs are excellent, build quality excellent and under a $1000... [ DENNIS  Aug 28, 2015 ]
You bet. [ Van  Aug 28, 2015 ]
By Marantz 200 watt speakers you are referring to Marantz speakers that can "handle" 200 watts, presumably at 8 Ohms impedance (pretty standard). Since the amp has a Speaker A (Left and Right), a Speaker B (Left and Right), and a Speaker A + B (Left and Right on each of two different sets of speakers) you are golden: yes, you can run all 4 speakers provided that you satisfy the following criteria: this amp needs to be configured for either 8 Ohm minimum or a 12 Ohm minimum when running A + B, meaning that you really need to ensure that both your sets of speakers are 8 Ohm impedance minimum. To the best of my knowledge, the 901's are in fact 8 Ohm, but you'll have to check the plaque on your speakers or the owners manual to ensure that the Marantz are 8 Ohm too. You should not (to the best of my knowledge) run an 8 Ohm set of speakers and a 4 Ohm set of speakers on the A + B configuration on this amp. [ Leo A.  Aug 28, 2015 ]
However, you cannot hook it up with an iPhone because it doesn't use usb [ ROBERT  Aug 06, 2016 ]
This amp does not have direct Sonos support, so you would need to use a Sonos product to connect into the system (like the Sonos Connect). [ Jeff  Apr 08, 2015 ]  Staff
I forwarded your question to an Advisor and they responded with the following: The AS801 buttons are designed with the same sturdier materials used in the Hi-FI components from Yamaha, and have a very sturdy well-made feel. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Apr 14, 2015 ]  Staff
Sorry Dude, My amp is only hooked up to PC (via USB) and a turntable, so no idea about other inputs. [ Van  Mar 09, 2015 ]
Hi John, Thanks for your prompt reply. Does coaxial cable or optical cable produce the same sound if I connect it to the back of Yamaha A-S801 to a DVD player? If my speakers have 4?, can I still choose either 10 or 12 gauge cable? Thanks for your help. Richie [ Richie  Mar 09, 2015 ]
Yes, you will get the same sound quality from a DVD player as a CD player. The amp is doing all the important work. For speaker cables, use any 10 or 12 gauge cable. "high end" speaker cables are just gonna cost you more. It's just copper. Hope this helps. [ John  Mar 09, 2015 ]
