Review Image by samdrucker
What a great piece of gear this is, I retired a long in the tooth Jolida tube amp in desperate need of a full recap for this. No hum or distortion out of this unit, just puer smooth power. Pushes the Polk XT70s beautifully. Also rear B+W bookshelf speakers and never breaks a sweat. No cooling fan required. Im Running it through a Yamaha EQ70 equalizer. And it just pushes clean quiet power. The amp functions flawlessly, with a soft mute feature. When a LP is done press mute, the volume lowers to a just audable level, push it again when your ready and it slowly ramps up to the previous preset level. There is no blutooth but thats an easy fix for 20 to 30 dollars buy a add on box and plug it in. Overall value is very good on this. You get a lot of head space for your buck. Im Running Polk XT70s and B and W 603s all 8ohms ,the rear swith set to high power, and this amp is 100% clean, powerfull and dosent even flinch or get warm. ... show more

Old School power and simplicity
Style: A-S801 Color: Black
After many years with surround sound, a move has forced me to simplify to two channels to fit the available space. I chose the Yamaha A-S801 integrated amplifier because it reminds me of the stereo amplifiers I admired in the 1970s, except that it includes optical and coaxial digital inputs and a USB DAC. Yamaha A-S801 provides old school class AB power that sounds smooth, clean, and powerful, and effortlessly drives my speakers to high volume. It is flexible enough to provide all the inputs and outputs I need. It is easy to configure and control. It is not permanently limited to an internal tuner, surround decoders, DSP, center and surround amplifier channels, complex menus and on-screen displays, or streaming device interface and services. I chose an external HD radio tuner. Optical digital input allows connecting my TV for PCM digital audio and my TV provides HDMI switching for Blu-ray player and digital video devices. The internal USB DAC allows me to choose any computer Operating System and streaming services. I connect a turntable and an external Bluetooth receiver. The variable loudness control is useful. A fixed loudness button would be useless. I wish it had tape monitor / signal processor loops and preamplifier outputs. I let my wife pick the color. This will likely be the last amplifier I will ever need. ... show more

The Yamaha A-S801SL is a fantastic integrated stereo amplifier
Style: A-S801 Color: Silver
The Yamaha A-S801SL is a fantastic integrated stereo amplifier. I am not exaggerating when I say that you will need to spend 2-3x more to get something better due to Hi-Fi diminishing returns. Clean, powerful, pretty linear/neutral, excellent sound-stage and separation, with good detail retrieval. Plenty of input options, the silver unit looks great, and has a nice build quality. The real gem here is the USB connection for a PC or streamer. I've read some of the other reviews about low loudness/SPL and lack of bass. I can assure you that the A-S801 has plenty of power (the power ratings are conservative, it's actually about 105 watts/channel into 8-ohms, and 150+ into 4-ohms) and it has tight/punchy bass, so I have a few thoughts... 1. Make sure that your streamer or source device is at 100% output volume. 2. Double-check your speaker wire/connection polarities and subwoofer phase if you're using a sub. 3. Many people are used to compressed music and over-emphasized, bloated bass. Use CD-quality or higher music and then allow some time to get used to how music should sound. Overall, I'm extremely happy that I got this unit for $799 during Black Friday, it's a steal at that price. I'm going back and playing my CD collection as well as streaming hi-res music from Qobuz via my Wiim Ultra, which is a superb combination. Curiously, USPS was chosen for the last mile of delivery, and that was a disaster. The package was dropped off by Amazon on-time with USPS in my city and was to be delivered later that day. But it was not delivered. Three days elapsed and USPS sent it to another city, then they sent it back to Denver (from which it had already transited), at which point it seemed like it was lost, before it found its way back to my city a second time. I cannot say anything positive for USPS. Amazon customer service was great though. ... show more

Review Image by Synth on a Plinth
This unit replaced a three-year-old entry level Marantz integrated amplifier. The unit was very warm sounding but just seemed to lack enough power to drive my 6 ohm Deftech tower speakers. The bass was always a bit thin, even with the loudness control turned on. So, I got online and started looking for an amp that would sound good but also provide more oomph to my speakers. For about a month I went back and forth between the Marantz PM8006 and the Yamaha A-S801. The thing that turned my mind in favor of the Yamaha was the A-S701 at a lower price. My network player has an internal DAC, so the DAC on the more expensive Yamaha really was not necessary. The variable loudness control was also a plus, as most of my music has be played at low level, being in a small apartment. Prime got the unit to me in two days, then the unboxing started. This integrated amp is sharp looking and built like a tank. Hookup of everything was quick and easy, then it was time for the true test, powering the unit on and playing some test tracks. My go-tos are 'The Nightfly' by Donald Fagen (pretty much anything by Steely Dan will work), the Belgian jazz rock group Abraxis, and many more obscure jazz recordings from Europe. The first thing that was noticeable was that the Yamaha was somewhat more neutral than the Marantz, unless you activated the 'CD Direct' or 'Pure Direct' modes. Taking away the internal toine controls gives you a HUGE boost of volume and clarity in the mid and treble ranges. Turning these buttons off lowered the volume significantly but WOW! When you turned the volume back up, the bottom end was full without being boomy or muddy and the mids and highs were defined but not shrill or harsh. I have been running the variable loudness in the 'flat' position which really does all aspects of the music justice. In the end this is a fine product with amazing sound and build quality. This will be in my stereo system for years to come! 5 year update: After many different speaker combinations, it appears that the Yamaha was not at fault; the DefTechs were notoriously inefficient. I now have a pair of Polk Es60s and they have never sounded so good. ... show more

Give It Time
Style: A-S501 Color: Black
I preface this review letting everyone know to give this amplifier a week to open up from a sound perspective. That has been my experience before making an assessment: Aesthetics: 4/5. I like the minimalistic look of this amplifier. However, I dislike Yamaha's decision to make tone controls rectangular. That decision baffles me actually, because many people who are critical of their audio sources tend to have OCD, like myself. Round tone controls would have made more sense. I purchased a black amplifier in order to avoid the asymmetrical look of the tone controls while in use. Build Quality: 5/5. At this price point, considering it is the 21st century, I find the build quality acceptable. It's on par with the Technics sl-100c. This means that even though this Yamaha may not be built as sturdy as in the past, it's still pretty good considering the price point and the century we live in. If one is looking for build quality from the days of yore, one will have to pay many times as much for a new amplifier. Note that if one is expecting an fm radio/tuner, they will have to buy it separately. Sound Quality: 4/5. This portion of a review will always be subjective. Normally, I have always enjoyed an open, lively sound. This amplifier doesn't meet that criteria. However, it has it's own unique sound, which when paired with the right equipment, can become addictive. This amplifier may not present all the sound details that one may be used to, but it manages to accentuate the details that matter. The sound is very clean, and I have heard details on occasion that I haven't noticed before. I must note that I don't use this amplifier for digital music. I only use it for vinyl playback and optical on occasion. The internal phono preamp is not that bad. Vocals sound fantastic. It definitely is not noisy, and records in worse condition can sound better through this unit. Perhaps that is why it may not sound lively at times; in order to produce less static and noise, Yamaha may have done this on purpose. I think Yamaha could have produced this amplifier without a phono preamp, and let folks decide on which one to purchase in order to better suit their tastes. In conclusion, I think this amplifier may appeal to those who are interested in a good, but different sound. I think Yamaha could have hit it out of the park with this product, if for a lower price the tone controls were round, and an internal phono preamp was not included. Still, I am enjoying the different sound that this amplifier produces. ... show more

Excellent Choice!
Style: A-S501 Color: Silver
I chose this amp for my PC-desktop. Paired with a HIFIMAN EF400 DAC, HIFIMAN Ayer Stealth headphones, NHT Super-zero bookshelf speakers and an SVS SB-1000 subwoofer, I accidentally wound up with an audiophile setup for my PC. It replaced a Logitech 5.1 THX DAC/speaker system I'd been listening to for 15 years. I was also listening to Sennheiser RS-180 wireless headphones at night. It was time to explore wired headphones, and so began the DAC and the Yamaha amplifier. The clarity and detail was a big improvement and the overall listening experience was more than I imagined it could be. I thought my hearing was getting bad. It turns out my tastes have changed somewhat over the years and now my "old music" began to sound much better with the new hardware. I found notes that were previously hidden by my old hardware. I like the layout of the controls, and although the Yamaha is kind of large for my desktop, it is conveniently placed right behind my keyboard. I play my music through Plex and Foobar2000 and get accurate playback on all musical selections. Windows feeds usb-audio to the DAC which then feeds line out to the Yamaha amp which then powers the 2.1 speaker configuration. The sound is extraordinary at any volume level. The NHT speakers sit an arm's-length away but the sound comes from the center of my keyboard. Lots of remaining headroom as the amp never reaches 50 percent of maximum power. Best of all is the clear, powerful and accurate pleasure from this popular amplifier. This is the best change I have ever made to my lifelong PC listening experiences. ... show more

and LOVE it. What a difference
Style: A-S801 Color: Black
This review is for Yamaha A-S801 model. Got it yesterday, and LOVE it. What a difference! This Yamaha is meant to replace my old TEAC AH-300, which was purchased 15 years ago as part of the TEAC mini-system. Came highly recommended by What Hi-Fi magazine at the time, and considered entry-level audiophile quality. I used it with Mission 700 speakers, also highly recommended by What Hi-Fi. Speakers are still the same, but the difference is stunning! Now, TEAC was much less powerful, at 35W per channel at 8Ohms, whereis Yamaha produces 100W at the same level. But if you would assume it got "louder" you would be wrong. The difference is not in loudness, it is in the detail. Yamaha opened a whole new sound-stage, several new dimensions in the music field. Everything sounds different now! Music got volume, and same old speakers produce quality I did not know they were capable of. To say I am "please" is not to say anything. Night and day. Highly recommended for all true music lovers! UPDATE: After a month of use I love this amp even more. In fact, I have updated my entire system, and tried different connections, so there is some new info I wanted to share. First of all, in addition to my good old Mission 700s I got two new floorstanding speakers, Dali Zensor 7, and a sub, B&W ASW610. Missions now serve as a back speakers, Dalis are in the front. Second, I have tried three types of sources for music: CD player (Marantz CD 6005, which has raving reviews), internet stream from Tidal (comes via USB cable from my computer) and playing CD's on the computer drive (also connected via the same USB cable). Here are the results: 1) Best sound by FAR comes from using computer drive for CDs via USB cable. 2.) Almost as good, but not quite, is streaming from Tidal (FLAC files, lossless quality) using Yamaha Steinberg USB driver and USB cable. 3) CD player, when connected via analogue cables, is inferior to the above. Why? Simple answer is - DA conversion. Not only Yamaha has a great DA converter (what they say here is true - SABRE Premier Audio DAC from ESS Technology, Inc is one of the best on the market today), but when you transfer data via USB cable it virtually eliminates jitter. And jitter is the MAJOR source of problems. Simply put, when you send raw data via USB it makes no difference what the source is - as long as data is not compressed, it is all the same. Problems begin when DA begins the conversion from Digital to Analogue. Most cheap CD players to poor job; computers do even worse job. SO when you get analogue out, it carries crappy signal and amp simply amplifies it. Amp itself cannot "clean up" the analogue signal; it can make it worse, but not better. The best it can do is to preserve it. For internal converter situation is different. Yamaha uses internal master clock, which "times" data correctly for the DA, and then DA transfers data from digital to analogue with beauty and clarity which is truly amazing. Can it be done by the CD player? Perhaps, if you spend 10000 dollars on the machine, it will have the same result. Do you want to? Its not that signal coming from a CD player via analogue connection is "bad", its just that it is not as good, not for a true audiophile. For anyone who wants to experience truly amazing sound, I would highly advise to AVOID analogue connections (RCA) at all costs. Simply forget about them. What about digital coax and optical? Well, it is better, but still there is a problem. If you use them, you do take advantage of Yamaha's SABRE DA converter, which is, again, great. BUT, you do not have advantage of using the internal master clock. Digital signal transferred via optical or digital coax has its own timing, which may be jittery. Now here it depends on the source: if you are using high quality CD player, timing may be precise and quality just as good. If not, - you will have problems. Question is - why bother, if your computer can work better and most likely will not cost you extra? In conclusion, I will highly recommend not just any model, but Yamaha A-S 801. This is the only model with built in USB DA converter, and the value of this small addition is ENORMOUS: when connected via USB it truly gives you the quality of 10 000 dollar CD player. I am not even mentioning the advantages of streaming, with its instant access to millions of CDs at a click of a mouse. Good job, Yamaha! ... show more
