Crutchfield Customer Review (What's this?)
Awesome Amp for the price. Plenty of power.
Cons: Wish it had an integrated power plugs for components.
Powering your speakers is about more than just brute force. The Yamaha A-S501 offers an excellent balance of power and agility, so your music sounds dynamic and bold without sounding bloated or distorted. In addition to its ample power output, this integrated amplifier employs a symmetrical circuit layout from inputs to outputs, along with an anti-resonance chassis. This keeps distortion and interference from cluttering the signal, for sound that's clean and clear. Your stereo speakers will come to life, for an engaging, detailed performance. Engage Pure Direct listening mode to bypass tone and loudness controls, for an even purer signal.
The A-S501 has six pairs of analog RCA inputs, including a phono input for connecting a turntable. But music sources aren't the only possibilities: optical and coaxial digital audio inputs let you bring video devices into the fold. Connect a TV or Blu-ray player to these inputs, and enjoy movie sound through your stereo speakers with this amp. It's a cost-effective way to build an excellent two-channel rig in your TV room that offers dynamic sound with a wide stereo image.
Awesome Amp for the price. Plenty of power.

Awesome Amp for the price. Plenty of power.
Cons: Wish it had an integrated power plugs for components.
Was looking for a good quality Integrated Amp and found the Yamaha A-S501 as a S&D for a good price point and thought I would give it a try. Sound quality is outstanding. I have an older Sony ES Receiver rated at 120 WPC and the Yamaha sounds more natural. I also hooked up my old Technics SL-1200 MK2 and love the sound of vinyl once again. This AMP really makes my B&W CM5 speakers come to life. The 501 is only 15 watts/ch less than the 701 and less expensive. I can't imagine there is much of a difference between the two AMP's.
Pros: Sound quality and features
Cons: Could use a light on volume knob.
This Integrated amp gives me all the power I need to drive my 2 sets of speakers.
Pros: Loudness control and pure direct sound
Someone complained (other supplier) that it lacked good bass and I could not disagree more. I have an old Carver HR772 that is rated with about 30 more watts per channel. The amp still works but the control for the inputs is not working properly...not bad for a 33 year plus receiver. It has great bass and the A-S501 is the same as far as I can tell. I arranged a quick swap to compare and the Yamaha is right there with the Carver. The only thing that I would like it to have is a means to tell the setting of the volume control. The Carver has a thin lighted slot which makes it easy to tell from across the room. The power is way more than needed to fill your living room unless you live in an auditorium.
Perfect. Simple. Excellent. Love it.
I was looking for 2 channel audiophile quality on a budget. I spent months reading and finally went with the A-s501. This amp has the cleanest sound I have ever heard. So clean that I joked the "A-S" in the model number stands for audio sanitation. I used this amp with a Chromecast Audio and Tidal Hi res, a high quality pioneer CD player, and a Turntable. I will say for this day and age the built in phone pre amp was very good and the Chromecast Audio worked well connected via TOS link. I started off with 2 channel but it lacked rhythm and bass, so I attached a sub woofer. this really improved the bass but the rhythm still sounded boring (thats the only way I can describe it). Listening to Tori Amos's piano or Coltran's sax was amazing. Then play George Clinton or Marly and it was like some one had sucked the life out of it. I am a music lover and have had the opportunity to use my speakers and other equipment with old Heath Kit, high end Marantz, and pioneer amps and had good bass with them. This amp how ever with out a Sub woofer lacked bass . Thanks to Crutchfield's great customer service and return policy I have decided to return this and save up for a higher end amp. As for Crutchfield I will never buy another piece of audio gear any place else. So helpful before and after purchase. Thank You!
Pros: Clean sound
Cons: No rhythm. With out Sub Woofer lacking in bass, making it Not a true 2 channel amp.
Very happy with this amp, specially with the price. Simple, very nice to look at and sounds great! My first Yamaha and love it so far! Great service by Tom!
Pros: Sounds great!
Cons: None so far...
Man this amp is a beast and is worth every penny. I'm using this with old Pioneer speakers and with an Technic Turntable SL D -202 I'm hearing details off of my Vinyl records like I've never heard before I also bought the Onkyo C-7030 CD player also and the details from my cd's on this Amp is amazing. I have to also say the sales person Tyler was very very helpful and I have to give kudos for the date it was promise to be delivered GREAT JOB GUYS
Pros: Worth the Money
i bought this just a week ago. i am using it with JBL ES-100 speakers. it sounds just as i dreamed of! crisp high and deep bass will blow your mind!
Pros: - very good sound - optical for tv connection - sub-out - variable loudness
Cons: - needed an LED on the volume nob - no USB
I'm impressed! On paper, the specs on this unit are heads and tails above the 20 year old Kenwood A/V receiver this replaced. In practice, what a difference. Sound from my turntable, CD player, even the TV is vastly improved. I love the 2 digital inputs, allowing me to take advantage of the built in DAC. It's nice getting back to the basics of stereo sound, as honestly, the concept, complexity, and sound of 5.1 or 7.1 home theater has never impressed me. The controls are very solid feeling, and build quality of the amp feels good. I moved my old ADC Sound Shaper down to the basement. Really isn't needed anymore.
Huge improvement over my $200 entry level Denon Reciever. 85 Watts powering Klipsch R-9F is VERY LOUD. I could have saved money and got 60 Watt version. I like the simple analog controls. My 50 year old ears love loudness control. My kids love Bass adjustment. I would have liked 2 or more optical inputs. I have only 2 inputs both toslink. (1) Chromecast Audio (2) TV. Bought $20 toslink to digital coax converter for TV.
Pros: Sounds great, lots of power. No distortion even when windows are shaking. Best rated amp I could find online for the price. Simple digital controls. Ability to select speaker impedance. Runs cool..
Cons: Only 1 toslink input
I purchases this unit to replace a 40 year old Onkyo A-7 integrated amp . The Onkyo had more features, but the Yamaha A-S501 has all that I needed, plus some new ones. I especially like the pure direct feature, which I use most of the time. It is impossible to read the position of the volume knob. To solve this problem I used a small piece of white graphic arts tape approximately 1/16" wide by 5/16" long and placed it over the small notch on top of the volume knob. I am now able to see the volume level position rotate from my couch using the remote. BTW the remote works very nicely. Although the phone section says it is for MM cartridges only, it works with my high output MC Blue Point cartridge without the need to turn up the volume control more than about 40 percent of it's total rotation. I am using the sub-out with my newly purchased Klipsch 10 R-SWi that I also bought from Crutchfield. Overall a very nice unit.
Pros: Pure direct feature, Sub-out
Good, succinct & well-directed advice from Sam regarding the best-suited Yamaha amplifier for my needs; prompt shipping; and Wow, what an amplifier! I wish that I had moved up from my Denon receiver to this Yamaha amplifier years ago - what an absolutely amazing difference - it makes full use of my B&W speakers! The only gripe, and it's a small one, is that the receiver does not have an integral power outlet in which I could have plugged my CD player - oh well! I certainly recommend Crutchfield.
I recently bought my first house and it has both a den and living room so I decided to put the turntable in a different room than the TV. This meant I needed another amp for the turntable since I wouldn't be able to plug it into the AV Receiver anymore. I was always underwhelmed by the quality of sound I got from my Onkyo digital AV Receiver when playing the turntable (it's awesome for TV/movies/games though!). I did some research and decided to get an integrated stereo amp - this Yamaha looked like it would be worth the investment. IT IS. I noticed an immediate and major improvement in the sound quality of playing vinyl on this beautiful amp! I love its design; it reminds me of the amp my mom had when I was little (although she had a vintage McIntosh tube amp). I love that there's no LCD Screen, and the knobs all feel great and hefty. This amp was definitely worth the purchase. For those curious, my current turntable setup is an Audio Technica AT-LP120, a pair of Polk Audio Monitor40 Series II bookshelf speakers and a Polk PSW10 10" subwoofer. I'm happy I don't live in an apartment anymore, because this thing gets LOUD. :D
Pros: Great and simple design Awesome sound quality Plenty of power
Cons: Pricey (but worth every penny)
So far so good. Purchased to replace system damaged in an earthquake 2 years ago. Enjoying CD collection again, but haven't connected to TV, laptop or streaming music yet.
Pros: Really drives the Klipsch Reference speakers.
Cons: None discovered yet.
Beautiful sound, power, and ease of operation. Powers my 4 Bose floor standing speakers with ease. No regrets on this replacement for my Onkyo I.A.
Excellent amp. Would recommend to others.
Clean sound. More than sufficient power for medium-sized room. As usual, Crutchfield service first-rate.
Pros: Straight-forward integrated amp. Clean sound.
Cons: Power/source LED's too small. Mute only reduces sound. No AC outlets for system components.
First I want to thank Crutchfield for their excellent and fast customer support. I have never seen or worked with any mail order company as efficient and professional as Crutchfield and no I was not given any speacial treatment to say that, I'm a real customer. I had been eyeing the A-S501 amp to run some older Klipsch Heresy II speakers. At first I was a bit dubious about pulling the trigger on it because I was also looking at some older vintage integrated amplifiers and receivers online because I prefer the old school silver look. I gave it more thought and Crutchfield has treated me with great service, so I preferred to continue that. I played Tin Pan Alley by Stevie Ray on vinyl and the richness in sound quality was so staggering I have never heard a stereo system this crystal clear. It amazes me that for just a few thousand dollars, a stereo system could sound this incredible. The Yamaha dished out an incredible amount of power and since the Heresy is such an efficient speakers system anyway, just turning the volume up a slightly over half way was bringing down the walls. This Yamaha rips with power and crystal clarity and base was solid too. Just a couple of minor things but nothing worth reducing the rating. The feeling on the knobs themselves doesn't feel as solid as older school amps and kind of have a more plastic kind of feel to them, but the looks are old school 70's and I can't fault Yamaha keeping this so incredibly affordable with this good a sound quality!
Pros: Awesome clarity and power.
Cons: Buttons feel a bit less solid.
Very good amp and at 85 watts per channel has plenty of power. The first thing I noticed when replacing my Sansui B-300 amp was the detail I herd of the cymbals. then after listening further the clearness of all the instruments. The bass is good but I'm running 4 floor standing speakers. I then hooked up my subwoofer and I'm still in the process of adjusting the sub to my liking but I'm not getting the mix I'm after, no fault of the amp of course,. I decided not to use my sub woofer and the amp handles the bass perfectly. I would suggest only using a sub if your only using bookshelf speakers. My next upgrade are new speakers. One drawback is how bad cd's sound. I started to play several different cd's and they just sounded tinny. Streaming music is much cleaner and pleasant to listen to. Better amp = more detail. And of course vinyl is the best .
Pros: Reproduces music perfectly , plenty of power at 85 watts
Cons: hard to see tiny indicator lights
I bought this amp to replace a Denon AVR-3803 which I loved for 2 channel music. The Yamaha A-S501 sound is very close the old Denon, I couldn't be happier. I have it paired with my Pinnacle Classic Gold Reference speakers, the sound is warm and quite accurate, bass is tight and it seems to bring out a bit more detail. Plenty of power and the volume can be turned up without harshness. I can listen to music for hours without fatigue. You will begin to notice good and bad recordings. The A-S501 will make good recordings sound better, but it makes poorer ones very noticeable. Fantastic value for the price.
Pros: Great sound, plenty of power, runs cool, Fantastic value.
Cons: No USB. The power cord is non-detachable.
I love my new Yamaha integrated amp works very good with my klipsch heresy speakers
I just got the Yamaha A-S501 and paired it up with a Fluance RT81 high fidelity turntable and a pair of Elac B6s. The amp is absolutely amazing. It has no problem powering the speakers, whatsoever. The speakers require a bit of juice so this is a perfect fit to drive them. The clarity and sound is impeccable. The turntable connects with ease as well and sounds fabulous. I have used 14 gauge wire to connect everything and also have connected my Apple TV (3rd Gen) to the amp via optical cable. I am able to stream my iTunes library and my Tidal account, all controlled by my cellphone. The look of the silver is truly refreshing and the overall performance has really made me feel great about my purchase. Highly recommend this product as well as Crutchfield for a fast and reliable delivery.
Pros: Incredible sound. Incredible power. Aesthetically pleasing.
Cons: If you're reading this, then you probably don't own it yet...so I feel bad for you. Lol.
I love this integrated amplifier. I wanted something specifically made just for old school music listening, I've found it with this product.....It sounds amazing paired with my Monitor Audio Bronze floor standing speakers......
Pros: Amazing sound...
Cons: Knobs should be metal, plastic a little fragile.....
My old Harman Kardon hk880 Vxi receiver died after 25 years. I loved the natural sound of that receiver and was tempted to have it repaired. But as with most electronics, technology does improve with time and I thought that it would probably not cost much more to get a new receiver (possibly even less). I was drawn to the specifications/reviews of this integrated amplifier and decided to take a chance--and I am so glad I did. The sound is also very natural and can get quite loud without distortion. Grant it I am not a professional audiophile but I am hearing things I have never heard before. I have a pair of Definitive Technology BP7006s which work well with this amp. I am most impressed with the built in DAC--by using this input with an Airport Express digital optical output, the music streamed from my iTunes on the iMac sounds so similar to CD's that I am going to get rid of my CD player. I really like the clean appearance of the front panel. This is an awesome integrated amp for the price point. I love it!
This product delivers the goods as promised. I am using this amp to drive a pair of Polk Tsi 200 bookshelf speakers and a Polk 111 subwoofer in my newly created bedroom sound system. The Yamaha does a great job of delivering powerful, clean and accurate sound through the Polks. My sources are a new Yamaha s300 CD player ( also purchased through Crutchfield along with the polks) and my old Technics 3300 turntable with a new Grado cartridge. They both sound terrific being fed through the new amp. I have decided to get back into vinyl once again after many years, and I have to say that listening to my old favorites on this new system makes me smile. Thank you Crutchfield for making the purchasing process so simple and for the careful packaging and on time delivery of all my new toys.
Pros: Great looks and clean powerful sound from all sources.
Cons: None really. Could use a couple of Ac outlets on rear panel to connect CD player, turntable, etc.
I purchased this amplifier with the intention of fulfilling a hobby of vinyl records. With my Definitive Technology BP10's sitting idle in the basement under plastic, I needed an amplifier that would provide enough power to my towers. This amp is nothing short of impressive in look, feel as well as power and layout of the controls. I have never heard these speakers come alive with such rich, full sound. I highly recommend this amplifier.
Pros: Power Controls Layout
Cons: Have not come across any yet.
There really isn't much to say. It's an stereo integrated amp and it's designed to do one thing. This one does it as well as I expected at it's price point. Does an adequate job of driving my Polk Audio RTi A7 speakers.
Pros: Does it's job
I recently replaced a high end Tandberg amplifier with a new Yamaha A-S501. The Tandberg was 30 years old and had developed a clipping issue in one channel after many years of use. The Yamaha compares very favorably to the old amp, driving my Klipsch towers in a very clean and powerful manner. The controls have a nice precise feel. I use the stereo to play blues backing tracks while playing along with my electric guitar and the Yamaha has plenty of power to keep up with the tube guitar amps. It's a quality component that delivers as advertised. Thanks to Crutchfield and Yamaha.
Pros: power, clarity, nice controls and features
Cons: hard to see the control settings on the black face without direct lighting
I purchased this unit to replace my venerable Yamaha A-1020 that (until it died) has been making thunder for me since I was stationed on Okinawa in 1985. While this unit doesn't have the features that my A-1020 had, it has the same great sound, and hopefully the same durability and longevity.
Pros: Simple, powerful and made by Yamaha.
Cons: No provision for a turntable with a moving coil cartridge, moving magnet only.
this amp looks and sounds beautiful. I would never buy an amp or receiver that does not have variable loudness.
Pros: variable loudness, digital to analog converter
Cons: cannot see where volume is at low light.
Pros: Great sound! Later this week I'm going with a cartridge upgrade (for my TT) and expect it to sound even better!
Cons: I don't notice much with the 'Pure Direct' button engaged.
Great! As advertised
My 20 year old Yamaha took a slow and painful death.... Then... with the help of the staff of Crutchfield I ordered my AS 501 ..... Kinda surprised that you can't hear it in the background....It is everything that an old music guy could ask for. My only complaint... or request is that they could have put a lighted volume indicator so that us old, blind guys could see the volume go up and down in the dark...... I know, this is trivial.... but..... The Amp is everything I wanted and needed....... Next... an upgrade to my HPM 100 Speakers.... which are still in tact . Thanks Guys.... You Are The BEST !!!!!!!
Pros: True Sound
Cons: Lighted Volume Indicator .... I know that is Silly .....................
Very happy with new Yamaha amplifier. Excellent power & sound quality. Product arrived quickly & in perfect condition. Using the amp for a dedicated vinyl system. Running 2 Klipsch rb-8ii speakers. Would recommend this amplifier.
Pros: Price Sound quality Color choice
Cons: Cheaper knobs
My next up grade be the 100w everything about the amplifier is great no complain
Pros: This changer is worth the money the only thing is the stand by i don't like the power company sounds lovely
I was looking for a good IA for a few months, and finally chose the Yamaha based on good looks, great price, and a lot of good reviews.
Pros: Sound is detailed without being peaky. It just sounds natural.
Cons: The buttons are a bit plasticy, and the power cord is no longer detachable for some reason. But all in all its a great integrated amp
I have just had a few hours with the amp and have, today, mated it to a Yamaha CD C600 disc player. The amp has plenty of power. The look is clean and simple and the setup was a breeze. The connection with the "Direct" option between the amp and the CD player is not yielding the spatial separation for which I was looking. I suspect the CD Player to be the culprit. I am running it thru 4 old JBL Jubal 65s and they are unusually bright anyway.
Pros: Nice design, Plenty of power, very friendly to install.
Cons: None yet.
I bought this to replace a home theater receiver that I was using mostly for vinyl playback. The difference is night and day. I use a diy vacuum tube phono preamp it sounds amazing with the "pure direct" feature. Plus if a certain record sounds flat I can use the nice bass/treble adjustments. I am very pleased.
Pros: Great for music. Well built and powerful
Cons: None so far...
Recently purchased this integrated amp as a "step up" for dedicated vinyl hi fi system. I had been using my 5.1 receiver and an outboard phono amp stage for records and decided enough was enough! This Yamaha amp is exactly as advertised. Its clear and clean, drives my speakers well and its simple. I tried it using the included phono stage and with my own phono stage and the one included in the AS 501 sounds better. I like the remote too. The loudness feature is a nice bonus. Since I am using this exclusively for my turntable I haven't tried any of the other inputs. I do like the pure direct feature as well. I have used that from time to time just to compare sounds. I would conclude that if you are like me and want to step up and get a dedicated stereo amp that doesn't break the bank or you want to use this as an entry back into 2 simple channel realm take a good look at this.
Pros: value, sound, simplicity, phono stage
Love It. Everything I wanted. Simple, clean and great sound.
I originally was looking at the Yamaha A-S301 because it had all the features that I needed to play my vinyl. But two people told me that the 301 didn't have enough power to drive my Vandesteen's so I opted for the 501. Yamaha is really being conservative when they rate this @ 85 watts. Now all I hear from my wife is "Turn that damn thing DOWN!" I haven't explored all the features yet, but so far I am very pleased with my purchase (needless to say, my wife isn't).
good product, easy set up. a bit muddy on the mid range and fuzz highs, but a lot better than most at this price range. Would estimate that one would have to spend 3 times as much to get to the next level of sonic bliss. very happy with product, as I knew what to expect. not much better out there for the price
Love this amp smooth power, nice style.
Pros: Power features price
Was as described nice unit sounds great
Excellent for the price
Pros: great sound, easy to use
I've been enjoying Yamaha hifi since 1977 (CR-2020 receiver); still using NS-670s, A-700u integrated amp... etc. I love the "natural sound," the contoured loudness control, the tone bypass option... and, on the S501, the digital-in and DAC. (I source a SONOS Connect via optical in.) Silver face is really nice looking. [boo! on plastic knobs.] This amp is perfect for my small room. Although some have said Yamaha equipment sounds "clinical," I believe it presents the source material as recorded - I'm able to adjust for my own sound preferences through speaker selection & placement. (So far through the A-S501 I've listened to "vintage" Yamaha NS-670s, KLH Model 6s, and brand new Wharfedale Denton 80th Anniversary Editions - all good, all different. Can't wait to try Klipsch KG4s - we'll see what "clinical" sounds like!
Pros: great uncolored sound; great features: digital-in (optical or coax), decent built-in DAC, tone bypass (Pure Direct), contoured loudness control; great looking, more-than-adequate power for my room & speakers
Cons: the knowledge of plastic knobs - but honestly, they don't look bad....
I replaced my 500 Watt Hafler amp and preamp with this. Outside of the improvement, I can't tell the difference (my apologies to Groucho).
Pros: Looks good, sounds good. Great sound. I like the variable loudness compensation. Doesn't seem to produce too much heat. I like the digital input as I pair this with a music subscription and a Windows computer.
Cons: I wish that the input indicator lights were larger. I have to bend down to see what the input the selector is set to. Also, there is almost no indication of the volume level. Indicator lights for that would be great. Minor gripes for sure. One more thing, it requires that nothing be set on top of it, as it vents out the top. I have a monitor on it with a very open base. So far, no problems.
Solid Product, Pure Direct really works.
Pros: Good features and very simple.
I can't complain about a single thing, I paired it with my MartinLogan ESL speakers and Onkyo CP-1050 turntable, huge sound upgrade from my Marantz HT I was using them with.
Bought this amp when it was on sale, but I would say it's worth the full price if you're looking for a affordable and quality piece of equipment. It works with my speakers well and looks quite nice in the silver finish that I purchased. A great upgrade to replace an older integrated amp.
Pros: Looks, Quality, Price, Power, Value, Design
Cons: No integrated bluetooth in this model, but optional accessory to purchase
Wow what a difference an integrated amp can make for music. I own a yamaha 7.2 receiver that I was using for movies & music rated at 90 watts per channel. Well when I compared the two the A-S501 blew it away! It sounded like it had twice the power even though it's rated 5 watts less. The music came alive & I heard subtle nuances I couldn't hear before. All music sounds better weather thru analog or digital connections. Very highly recomended!
Pros: Looks, sound, and power
Cons: Non so far
Powerful, Efficient, with wonderful sound reproduction. Was replacement for a original Yamaha A500 amp, which was over 30 years old and played hard. Can't wait to utilize the digital options included with amp this is from a real analog lover. Albums and cassettes have new life. Could even power my moving coil stylus through circuit. All in all great product
I love the sound that this unit provides. I would have given it 5 stars except for the control knobs. There should have been a display window like the one on the R-S-500 Receiver so that you can see the audio selection.
Pros: Great Amp.
Cons: Needs a better selection indicator.
I wanted the best value to drive my GoldenEar Triton 7s, and I found it with the Yamaha AS-501. I by-pass the tone controls with the "Pure Direct" option engaged, and I get the clean sound I wanted. What sold me on the Yamaha Integrated amplifier was that I can attach my Blue-ray device to deliver great 2.1 sound--yes, sub-woofer and phono outs are part of this great deal. My unit came from the Outlet shop and was sold as a "scratch and dent." The Yamaha arrived in the original box with no scratches, dents, smudges--although a small chunk of Styrofoam had broken off from the packaging holding the unit. I can live with that! Finally, I have to say that the remote with this unit is fantastic due to the uncluttered layout of the buttons. I love the way when I press MUTE, the volume ramps down to a quite yet audible level.
Pros: Value. No frills, but the unit delivers clean, uncolored power that can drive 4 ohm or 8 ohm speakers. Remote is uncluttered which means you can quickly locate the volume and mute button when you need them.
Cons: The dials have the look of brushed aluminum, but they are plastic; not a problem for me but maybe a knock for some.
I purchased this amp as a backup to my Trends 10.1 and a replacement for my av Onkyo TX-SR705 in my audio setup and could not be more pleased. Av amps in my opinion are not very musical and the power ratings seem to be inflated. The amp is powering a pair of klipsch rf-82's and the music sounds amazing; the noise floor is seriously low, this thing does not make a peep until you finally hit play on your source. As Yamaha states, it's very natural sounding does not color the music at all and is very dynamic. Unless you are in a very large room you will most likely never go half way up on the volume dial with efficient speakers. The amp is very flexible especially with the option to go optical or coax for digital sources and loads of analog inputs. The primary use for this amp in my application is the playing of lossless media, direct cd and also the occasional tv source via digital. All sounds crystal clear and well presented. I'm so impressed by this amp I will mostly likely replace another existing amp on another floor of my house. The unit is very well made and all who have been asking about the knobs it's true they seem to be a very nice plastic that look very much like milled aluminum; can't tell until you touch them. You will be hard pressed to find anything that sounds as good, well made, power output for this price bracket. Yamaha spent the money right and that is what makes this thing sing.
Pros: Look, simplicity, sound, construction, remote control, flexibility, power, price
Cons: At this price....none.
I purchased the A-S501 to replace an older integrated I had. I was slightly concerned about how the sound would differ from my 70's amp that I was previously using but the Yamaha has really blown me away with it's sound quality. I love having the flexibility with digital and analog inputs and this is a definite upgrade to my previous setup. The only negative I would state is that on Yamaha USA's website they list this unit as having all aluminum face and aluminum knobs but I can report that all of the knobs are plastic, although very nice looking plastic.

"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-S501 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-S501 reproduces high sound quality and musically rich sound.
Proprietary Yamaha Technologies: The Yamaha AS-501 integrated amplifier employs proprietary Yamaha technologies for optimum performance and sound reproductions.
High Current Amplifier: The Yamaha A-S501 features a dynamic, high current stereo amplifier with low impedance drive capability. The amp is rated at 85 watts x 2-channels, measured from 20-20 kHz into 8Ω with 0.019% THD (100 watts x 2-channels, measured from 20-20 kHz into 6Ω with 0.038% THD).
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.
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 our 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
Pure Direct Mode: The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
Variable Loudness Control: The A-S501 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:
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.
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.
Gold-Plated Terminals: The Yamaha A-S501 has gold-plated terminals for all of its inputs and outputs. These gold-plated terminals ensure a high quality connection that prevents signal loss.
Analog & Digital Inputs: The Yamaha A-S501 integrated amplifier offers analog & digital inputs for connection of a variety of home audio components.
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-S501 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.

Wanted a good integrated amplifier... this has many attributes. Awesome power supply, excellent phono preamp, sub out, digital input for bluetooth and CD. Perfect. [ Sheila Apr 08, 2017 ]
great reviews--Yamaha has never failed me [ NELSON D Mar 08, 2017 ]
After hours/days of research I settled on this amplifier because it has three things that every other amplifier in its price range lacks (or has 2/3 options): 1) Phono input - everyone seems to be getting back into records these days and I am no different. This is a step up from the built-in phono pre-amp on my turn table. 2) Built-in DAC - I purchased this to be my man do-it-all amplifier. 3) Subwoofer out - a rarity in its price range.

Looking for a high-performance, reasonably priced stereo only integrated amp to replace an older Sony 5.1 receiver. [ Brian Dec 17, 2015 ]
Hi Mike! Got me there Buddy. The only things connected to the Yamaha is a cd player and a old Pioneer turntable but haven't played with the dac yet. Have you asked the guy's from Crutchfield? Can you keep me posted? Sorry... Victor [ VICTOR Jun 09, 2018 ]
Looks to me that you would have to use analog via RCA type connectors. If you wanted to connect using one of the digital cables you need to purchase the dacmagic plus. [ UncleDave7 Jun 06, 2018 ]
I see nothing in the specs that would indicate that the tuner input is any different than the other inputs. There is no mention of a low band filter in the manual so I assume (with 51% confidence) that there is none. The Toslink and coax inputs both accept PCM stereo signals. Any difference between the two would be more a result of the cable you are using. I personally can not tell much difference but then I use consumer-grade cables. The opinion of some reviewers is that the coax is slightly better unless you use a high-quality optical cable - AudioQuest, for example. You can have one device connected to Toslink and another connected to coax and select either from the front panel. Hope this helps. [ Howard May 25, 2018 ]
Not sure if the frequency response are the same, but the tuner, CD, tape deck all sound fantastic. The Toslink and coax digital are two separate cables of I'm not mistaken.....sorry. [ Cyril May 25, 2018 ]
No, it doesn't, the Digital Inputs only support 2ch PCM. [ MARCO A Aug 12, 2016 ]

My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159 [ Larry May 22, 2016 ] Staff
I don't have any Bose speakers so, I can't say for sure, However, my advice is to look at the spec.'s on the Bose speakers. Most speakers are 8 Ohm speakers and they may require a minimum amount of power to drive them. For example I have some old AR-3 speakers that were 4 Ohm speakers and required a minimum of 25 Watts per speaker, just to start to drive them. However, it is very hard to find an Amp that will put out the 4 Ohms to drive my speakers. This particular unit has a switch on the back to drive either 4 Ohm, or 8 Ohm speakers, which is what I was looking for. According to the spec's for this unit, this unit will put out 100 Watts per channel @ 4 Ohms, which should be more than enough to drive my speakers. If the Bose speakers are 8 Ohm speakers, which are much more common, see what the minimum spec's are for driving them at 8 Ohms. According to the spec sheet for this unit, this unit will put out at least 85 Watts per channel and I suspect that the Bose speakers requirements will be under that amount, which will be OK, but I am not sure. Check the Bose speaker Spec Sheet to see what the requirements actually are. Another concern would be to note what is the maximum amount of power that the Bose speakers will take. In earlier years, I have blown out some speakers by applying much more power to the speakers than they were designed to take, but fortunately for me the particular speakers that blew were kind of cheap so the lesson wasn't very costly, but I took note for future considerations. Hope this information will help in making your decision. Lot's of luck [ JAMES Aug 04, 2015 ]
I have two sets of Bose speakers powered by this amp & they work fine,. But, my speakers are ancient, so I'm not sure about the new Bose series speakers. [ Donald E. Aug 03, 2015 ]
yes they should work with bose I recommend monster cable for your connection youll love it ren [ michael anthony Aug 02, 2015 ]
Yes, amp is very capable to power almost any speaker; as far as Bose goes since they never mention any of their specs I would say this amp would most likely power them with not even knowing they are there. [ N1K Aug 02, 2015 ]
Yes, it will work fine. [ TOMY Aug 02, 2015 ]
I DON'T HAVE BOSE SPEAKERS BUT THIS AMP WORKS VERY WELL WITH KLIPSCH REFERENCE BOOKSHELF SPEAKERS - PRICED AROUND $350 A PAIR. [ ANDREW Aug 02, 2015 ]
I'm sorry, but I don't think that I can answer your question. I do note that there are 2 sets of RCA Out connections on the back of the unit, but I have no idea if they would as a pre-amp. I assume that each set might be able to be used as a tap monitor loop because of the in and out function, but that was not my reason for purchasing this particular unit. I have a pair of Acoustic Research AR-3 speakers that I purchased back in the middle 50's that were some really great speakers for my purposes and I had a Heathkit Amp that I constructed from a kit in the same time period to drive them. My amp lasted quite a few years, but it had old style fuses to protect the device. The old fuses were no longer made and I would blow the fuses pretty regular. So, recently, a recommended replacement fuse was put in the amp and the amp burned. So much for the amp. My main problem was that the speakers were 4 ohm speakers and very few, if any, companies made a reasonably priced amp that would provide the 4 ohms required to drive the speakers. This unit has the ability to put out the 4 ohms and have more than enough power to drive my speakers and no fuses to buy. The holidays are here now and I haven't had enough time to hook everything up, so I don't know how they will work, however, I suspect that the old speakers just might blow before the new amp does. In any case, I don't have an answer for Mike D's problem and I am hoping that I will be able to relive those wonderful days of my youth, when I finally am able to finally get this unit hooked up and operating and listening to my old AR-3 speakers. [ JAMES Dec 09, 2014 ]
yes [ DOUG Dec 07, 2014 ]
I have my yamaha a-s501 biwired to a pair of klipsch rb-81II large bookshelf speakers used for dedicated turntable set up. More than enough power for these beasts. [ ANDREW J Aug 12, 2017 ]
The Yamaha 501 should not have any problem powering the speakers that you are looking at. The amp can deliver 85 watts into an 8 ohm load and 100 watts per channel into 6 ohm speakers. Your speakers recommend 50-120, so you will be in the sweet end of that range with the 501. My experience with the Yamaha and bookshelf speakers rated at 88 decibel sensitivity is quite powerful and high volume levels at at about a 12 o'clock volume setting. My speaker have a nominal impedance of 8 ohms, your 6 ohm speakers would get a bit more power out of the amp. Hope this helps. [ Arthur Aug 11, 2017 ]
Yes. I am using that amp with 6 ohm speakers rated at 85 db and it sounds great [ R Aug 11, 2017 ]
You should be able to record any source that you are listening to onto your tape deck or cd recorder by attaching them to either the line 2 or line 3 inputs and rec outputs as described on page 9 of the owners manual. I have not done this myself yet, but it should be rather straightforward. I definetly do recommend this amp as I am very happy with pure sound quality and ample power that it provides. [ Arthur Jun 16, 2017 ]
Steven, If I'm understanding your questions correctly then yes, the Yamaha S501 amplifier has plenty of input/outputs that should accomodate all of your decks. It's a super clean unit with plenty of power. Thanks [ Paul Jun 16, 2017 ]
thanks for your question. The unit provides 85 watts x 2 channels into 8 ohms (20-20,000 Hz) at 0.019% THD. You can find this information on the main product page under "Product Highlights". Hope this helps. [ Kenny Apr 07, 2017 ] Staff
Generally, an integrated amplifier will sound much better than a receiver. however, I had a HK Blu-ray/ tuner /amp a BD model I think all built in along side this exact Yamaha. While the HK was good, the Yamaha was an over all more detailed and better amp.My suggestion is why don't you purchase the integrated and try it in your own environment that way you be the judge. If you are not satisfied crutchfied has an excellent return policy. But I strongly think you are going to like the Yamaha. Good luck. [ Alexis Feb 06, 2017 ]
Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Kenny Dec 12, 2016 ] Staff
Yes, the 501 has a built-in preamp, but if your TT has it's own preamp just connect through Line 1, 2,or 3. I never tried two preamps, but I'm sure it would cause considerable sound distortion. [ John May 09, 2016 ]
All answers were very helpful and I wold like to thank all. [ Edward May 07, 2016 ]
Ed i have a non-preamp numark going through my 501. naturally the volume is much lower than my tascam cdrw and kenwood tape deck ( which have 5 and 3 watts of power.) i can only imagine your turn table's extra power will ad to total quality. JON [ jon May 07, 2016 ]
Edward you don't want to go through two (2) pre-amps. If you cannot by-pass your built-in pre-amp on your turntable, then you want to connect to either the 'Tuner' input or 'Line 1' input on the back of the device. The turntable pre-amp that is included with this Yamaha integrated amp is fine though limited to MM (moving magnet), not MC (moving coil). This is a very good sounding IA but give it some time. I did not like it at first, but after two weeks of running it (burn in) it sounded great! It also has plenty of power! Kevin [ Kevin May 06, 2016 ]
I would connect the turntable to one of the line inputs, since it has already been preamplified. I would NOT connect to the phono input, as I would expect real distortion from two gain stages. I come from the OLD NAD 2030 background (absolutely loved it), and am very happy with this Yamaha. [ GARY K May 06, 2016 ]
I would not amplify it twice. Since your phone has a preamp already I would just connect it to a line in. [ N1K May 06, 2016 ]
Don't know for sure but two preamps in series sounds a little scary. Would output from first preamp be outside or overload amp input limit? Great, l answered question with a question! Love this integrated amp!!!! [ Eugene May 06, 2016 ]
I haven't used it so I don't know, but in the past you need an output, not an input into another device that can "record" the incoming signal. There is no device on or no media to insert the unit. So only if you can use an output digital or analog on the unit will you succeed, in my opinion. [ LARRY Oct 19, 2015 ]
David I have this amp and I don't know of any connection for Spotify or any other internet based music stream. [ Joseph Jun 04, 2015 ]
Not to my knowledge. However if you have spot iffy on an iPad, iPhone etc you can use the app and run it through the amp using AirPlay. [ LARRY Jun 03, 2015 ]
no online connection on this device [ MPW Jun 03, 2015 ]
The A-S501 has no Internet connected services. It's purely a stereo amplifier that will power speakers and take various analogue and digital inputs. I use mine with an Apple TV connected via optical input and play Spotify through the Apple TV. Works great! [ Samuel Jun 03, 2015 ]
No, it does not. [ N1K Jun 03, 2015 ]
Not that I find but it is Bluetooth ready. I purchased the Yamaha YBA-11 adapter and it works great with Android phone and IPad. So, I would think you could play through Spotify that way [ Eugene Jun 03, 2015 ]
Sorry, I don't have an answer for you. I don't know the ohm or power requirements of your speakers or how many you are powering. [ Donald E. Mar 01, 2015 ]

Hi Leigh I'm not sure. I have Bose 301's hooked up to it. Stuart [ Stuart Feb 24, 2015 ]
Leigh I have this amp driving a pair of Bose 301's. I am pleased with the sound I'm getting. Not sure where your speakers compare to mine but hopefully you can gauge the probability based on my speaker source? [ Joseph Feb 24, 2015 ]
Very eas easily. I have a pair of rf-82s and it sounds wonderful through this amp. The 82s are very efficient at 98 db per watt. My back up amp is only rated at 10 watts and the 82's scream. [ N1K Feb 24, 2015 ]
I asked Yamaha repair techs this question and was told that even though it isn't listed in the manual, the sub out filters out anything above 90Hz. [ Christopher Mar 12, 2016 ]
I forwarded your question to an Advisor and they responded with the following: There is not a separate subwoofer crossover on the amplifier. You would need to adjust and control this from the subwoofer itself. The bass control affects the speakers and subwoofer and it is set at 400 Hz. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Jan 07, 2015 ] Staff
The knobs are plastic. If you use the remote, this may not matter as much. [ Donald E. Dec 29, 2014 ]
Thank you for replying to my question.Some people say plastic and some say metal.I guess I will have to take a chance to be sure.If it doesn't then I will return it.Thanks again. [ leigh Dec 26, 2014 ]
Metal [ Stuart Dec 26, 2014 ]
Plastic. Unfortunately makes a high quality device feel less so. But don't let the cheap knobs overly influence your purchase. It's performance is excellent, so far, with tuner, CD, cassette deck (still holding on to the past), and Bluetooth inputs. [ Eugene Dec 26, 2014 ]
