Style: A-S701
Color: Silver
First off, I've been using vintage equipment for a while. The problem is the constant breakdown of 40 year old equipment so i decided to go modern. I didn't want another BPC receiver, I've had two, a pioneer and a Sony, neither of which had any any real output, I had to turn them way up to get loud but was never satisfied with the sound quality, but then I found the Yamaha integrated amp with the silver face. Very clean lines, not cluttered with multiple switches. Its paired with a set of Klipsch R26FA speakers. The amp has only an A, B and A+B selection. A is hooked to the front speakers while the B is hooked to the top firing Atmos speakers. It has a subwoofer output which I attached to a Klipsch K100SW powered subwoofer. I have a large listening room and this set up fills the room with sound that you can feel as well as hear. I still use a vintage turntable and tape deck but I have an Echo Link hooked up as well. The sound is awesome, but then I said that already. I also have a top of the line modern Panasonic Blu-ray hooked up, when I watch a concert video it's almost like being there. A vintage Pioneer tuner completes the package however I have ordered the tuner from Yamaha so I can utilize the presets which can be accessed from the remote. With 100WPC at 8 ohms, it's got plenty of room, I barely turn it half way up and thats loud enough especially since i added the subwoofer. I rarely have to move the bass/treble control from neutral to get astonishing sound. Yamaha also has a "pure" CD and all input selector that bypasses all the internal filters if you want to hear exactly what the component signal sounds like. This becomes in handy if you have adjusted the bass/treble controls and want to revert back to the neutral setting without having to adjust the controls afterwards. There are three additional inputs as well as inputs for phono, cd, tuner and optic cable. Another plus of modern equipment is remote control. My Pioneer and Sony receivers had incredibly complicated remotes that usually required reading the instructions whenever i wanted to do anything with it other than powering on/off or adjusting volume. The remote with this model is like the amp, simple clean lines/controls and doesn't require a rocket science degree to comprehend. This amp also has an analog volume control which moves when you access it via the remote. Cons: no outlets on the amp. Not a big deal but I like having my turntable hooked up to an amp switched outlet so it can't turn on unless the amp is turned on. It would also be nice if it had the ability to run 3 channels simultaneously so I could bi-wire the front speakers but honestly my sound is impressive. Also no tape monitor which limits what I can do with my vintage equalizer. Another lack is a low volume bass boost, but since the bass is usually at neutral I've found I can turn it up a smidgen to get improved bass at low volume. By doing this and utilizing the Pure Input it is almost like having the bass boost option. Another improvment Yamaha could have added is a mute function on the amp control face. It does have one on the remote. There is "Loudness" control on the panel. This control can variably lower the volume without adjusting the main volume control. It is useful when I want to change the music selection on Alexa since she can't hear me talking when I have the volume pumped up. Afterwards i can resume at the volume I had previously dialed in. No HDMI input but then this isn't meant for a home theater. On the other hand it does have an optic input. It does have a USB output to power something, i don't use it yet, maybe I can power my echo dot with it or perhaps dress up the rack with an led tape to add a little color...or not The control and power on indicator lights could be a little bigger or brighter. From across the room I cant see them at all Overall impression...I'm very happy with this amp. Yamaha signature "natural sound". It plays my music clearly and loud enough to piss off the neighborhood if I wanted to. I wouldn't recommend it for a home theater system since it only has two speaker channels but that isn't what I wanted it for. If you want a clean sound and a silver vintage look without breaking the bank you couldn't go wrong with this amp. Just be sure to get a set of speakers with the legs to run the horsepower and you won't be disappointed

Style: A-S801
Color: Silver
The Yamaha A-S801 is one of three systems I’ve fully optimized, and I can confidently say it’s the cornerstone of my budget-friendly yet seriously capable setup. Getting back into the audio hobby at a deeper level, I wasn’t expecting this level of performance—but the A-S801 has far exceeded all expectations. Its output is clean, powerful, and remarkably neutral, which makes it the perfect foundation for customizing your sound through external DACs, streamers, and other sources. There's no worry about underpowering speakers—this amp can confidently drive 90% of what’s on the market, including many speakers costing far more than the amp itself. I’ve paired it with Cabasse Murano Alto floorstanders, a FiiO R2R K11 DAC, and a WiiM Ultra streamer—an absolutely synergistic combination. While this may not be an “endgame” setup, the musical enjoyment it delivers is undeniable. The A-S801 opens the door to a wide range of speaker pairings and digital source options, making it one of the best sub-$1000 integrated amps out there. Like many others have said: this amp punches way above its price class. Totally impressed.

The A-S301 is simply awesome! Completely clean sound, pure power. Lots of connectivity options. Remote is well designed. Love that the volume ramps down and up when you mute or power on rather than a sudden blast. 4.0 Yamaha!

Style: A-S301
Color: Black
This review is for the A-S301, as Amazon seems to lump all the reviews for all the models together. I wanted to build a small 2ch system for music in my small office. Keeping to a budget under $400 I was cross shopping this with the NAD C 316BEE and the Cambridge Audio Azur 351. The connectivity options won out (the NAD would need a phono preamp, and both a DAC. I realize the Cambridge has one, but its USB only. I needed the Optical and Coax connectors for my equipment). The Yamaha, on paper anyways, also had more power which, while not important for my use, was a bonus. Even though the Yamaha was a much bigger and bulkier amp, I went for it. As I said in the headline, the item works great, but I had to replace my first one. The first one, while working perfectly and sounding great had a defect in which if the unit was turned off, a relay would randomly click inside, sometimes within minutes or even seconds. Annoying for sure. Assuming maybe I had bad power going to it, I tried different outlets and even brought it to a different location, no improvement. That being said once powered up, it worked perfectly. I called Yamaha support and they told me this behavior was not normal, so Amazon to the rescue, I got a new one. The new one works great and no bizarre clicking. Now for the review, I certainly don't consider myself an "audiophile" my expectations are probably "mid-fi" at best and this unit meets my expectations. I have it connected to a pair of SVS Prime Bookshelf speakers. For sources, I have connected a Vizio TV, a PS3 Slim, a Stanton T.92USB Turntable, and a Yamaha YBA-11 Bluetooth Audio Adapter. The PS3 is connected via HDMI to the TV, and the TV optically to the amp's built-in DAC. The Bluetooth Adapter is connected to the DAC as well, via coaxial, and its power is being provided by the included USB connector on the amplifier. The turntable, while offering pretty much every means of connection possible, is being connected to the "Phono" input of the amp via an Audioquest Evergreen RCA cable. So for the build quality, it has a nice thick and solid brushed aluminium face plate but yes, the knobs are plastic. The controls however do have a nice action to them and work very well. Looking inside, the layout is very nice including dual heatsinks and nice oversized components. Wiring seems to be kept to a minimum and every section is isolated to its own separate circuit board. The circuit and component layout seems to be a pretty thoughtful design. for both short signal paths and serviceability. Around back are a nice set of binding post connectors for both an A and B set of speakers, a permanently attached power cord, impedance switch, a switch to enable an energy saving auto power off (after 8 ours of non-use) plenty of RCA inputs(5), a coax and optical digital input for the built-in DAC plus a USB port to supply 5v power. Please note, you cannot connect a USB audio source to this jack, its for power only. Last but certainly not least, a Phono input suitable for MM cartridges. The included remote, well its functional, but has many small non backlit, hard to read buttons and feels very cheap and plasticy. Its also silver, funny being that the A-S301 is only available in black in the U.S. I wish it matched. Like I said, functional, but kind of disappointing compared to the amp itself. I've had no problems with the DAC and any of its digital inputs. They sync up and remain connected, and the sound, while some may say is not as good as a standalone unit, sounds very good to my ears, smooth and warm sounding. Personally I think it sounds better than the same inputs on my Marantz NR-1604, a 7.1 receiver that I also own, but my speakers could be coming into play here. The RCA connections are fine, no hum, hiss, or anything bad. As for the phono stage, I've read some reviews that say its not all that great. Well to me with my turntable, (Stanton T.92USB) vinyl has never sounded better. I should mention I upgraded the terrible included cartridge to an Ortofon S-120. Before connecting to this amp, the turntable was connected to my Marantz and I have tried all the inputs. USB to a PC was by far the worst, followed by RCA line level, Coax digital actually sounded a bit better than RCA, go figure. Now using the proper phono input offered by this Yamaha the sound is by far the best. Bass is much more solid, mids are smooth, and highs, which for some reason were always lacking are once again present. I've had the T.92 turntable for years and to be honest have never really liked the sound. This Yamaha is finally making it sound like it should have in the first place. I can only imagine what an upgraded more for listening and not DJ use turntable may bring. So for me, the built-in phono preamp is very much a win. Finally onto the overall sound. The amp is still "burning-in" as they say, and while I generally don't buy into that, I did notice a difference when I got my replacement. I had used the first one for almost 2 weeks and had come to really enjoy the sound, very neutral, smooth, but articulate and powerful for its class. When I received the replacement, how can I say it, the sound was almost "boxed-in" by comparison. That being said, I now have probably 15 hours on the new one and its already opening up and sounding better and better as time goes on, so be sure to give it some hours of use before passing judgement on the sound. My other amp choices might have been better, but i'll never know. I do feel with music especially, the sound does compare very favorably to my Marantz NR-1604, a more expensive 7.1 unit. The Yamaha just sounds a bit warmer and inviting, especially when pushed. The 60w/ch power rating is probably a bit on the conservative side. The amp has no problems driving my SVS Prime Bookshelf speakers (8ohm, 87db sensitivity, 20-150w recommended power, 6.5" woofer, 1" tweeter) to extremely loud levels if asked. So to sum it up, the A-S301 offers nice sound, plenty of power, excellent connectivity, and great build quality. The built-in phono stage and DAC are NOT mediocre but actually sound pretty nice to me, and for most may never need to be upgraded. This is a great entry into better than average 2 ch audio. As long as I don't have any issues with the replacement, I hope to be happy for quite some time. UPDATE 4/10/16 Since this review I have upgraded some of my equipment (my turntable to a Pro-Ject Debut Carbon DC, and just today a U-Turn Audio Pluto phono preamp.) I have been using the Pro-Ject turntable for months and it has been great, a solid upgrade from my old Stanton. This Yamaha continues to work without issue. I wanted to talk about the built-in phono preamp. While many have complained that the preamp was sub par, I disagreed, however had no real basis for comparison. Now I do. I still stand by that the built-in works well, but its not the "end all be all" As I mentioned earlier, I just purchased a U-Turn Audio Pluto preamp due to some very favorable reviews online. After some serious A-B testing, its probably not surprising that the Pluto sounds better, the difference however is not as huge as one might think. Output level is similar enough not to matter. Background noise/hum is a little cleaner on the Pluto. Bass output is comparable as are the highs. Where the Pluto excels is at midbass, much more pronounced than the Yamaha built-in but certainly not too thick or muddy. The resulting sound is warmer and fuller, and in a good way. Certain LPs had an almost brittle or thin sound quality and could be fatiguing at higher volumes when played through the built-in. I'll be keeping the Pluto. All that said, given the price point of this amp, the built in is sufficient and still does a decent job for what it is, although if the purchase of the Yamaha is based solely on inclusion of the preamp (it was for me) just know that going with a dedicated preamp may yeild more pleasant results.
