AIYIMAT9 100W*2 Bluetooth Stereo Amplifier Class D Amp 2.0/2.1 Channel Tube Power Amp with PC-USB DAC Coaxial Optical inputs &VU Meter & Bass Treble Tone Control for Home Stereo Speakers

This amp Is magic, for the small size and the low cost it is just magic. This amplifier sounds better, to me, than a lot of more expensive amplifiers. it has very detail sound. Sounds better than my 1980's Kenwood amplifier(which I bought when I was just 17 years old). Sounds better than my Sony 2 Chanel amplifier. Does it blow them out of thee water? No, but to my ears it sounds better. The build quality is very good and the aesthetic design is really good too. Only issue I have is that remote should have more functionality, like having Bass, Treble and balance controls on it, and not having a bunch of none functioning buttons on it. It's a generic remote probably used with various Aiyima products. still the remote does control pwer on and off , volume up and down, mute and changing tracks with blutooth. Also the amplifier needs to warm up and breaking in before you get the best sound. It will sound a little thin the first time you turn it on but the sound gradually gets fuller and better (Much better) as you listen the first few hours. Probably breaking in the Vacuum tubes. Over all I am happy with the amp and glad I bought it.

This pint-sized little wonder sounds so good, I actually prefer bit to my $1300+ integrated amp. It ticks all the boxes I was looking for: optical input for TV, RCA for my turntable (with a built-in phono pre), and USB input for streaming from my computer. Plus, it has a remote, which is important to me for using with the TV. It lacks a headphone amp, but that's a fair trade off for the price point (I have an external headphone amp).Paired with my Elac DBR62 speakers, the sound is addictive, with bouncy bass, punchy mids, and sparkling highs. Sadly, it did take two tries to get a good one, as the remote stopped working on my first one within a day. As always, Amazon came through and sent a replacement within a day.

<Honest review here>Woah. For the price, this amp is a powerhouse. Paired with my klipsch rp-600m it sounds fantastic. Room filling sound, incredible detail on music, & films. Along with the versatility options, this little guy is solid in the hand, packs a good punch, and even looks great. For what its worth the packaging was on par for a rainy day, the tubes were slightly bent at the nodes yet still work just fine. there is a slight wiggle when inserted but who doesnt like a little four play? ;) a warm hum when powered on, yes it has a click when not in use. Like when youre picking the next song or movie, Totally not an issue. After a few weeks of using this amp I've had zero issues and have accepted that anything could happen and it would be money well spent. Who knows, maybe it will outlast us all. Its really all I needed for now.. Im hearing things I've never heard before, Blade runner, AMAZING. Twin peaks FWWM, brilliant. Goodfellas, sopranos, fuggetaboutit. And the meter works well, even kept up with the Great Neil Peart!

After much fan fare, great reviews (cheap audio man etc.) and waiting for it to finally come back in stock, I have to say I’m super pleased with this little beast. I have it hooked up to my Klipsch RP600M, Apple AirPort express via optical for Airplay2, and my turntable via Fosi Audio Box X2 preamp to the RCA inputs. I also have my Klipsch powered sub attached via the Aux out. The majority of my listening has been done via Apple Music through the optical/DAC. Right off bat, the sound is fantastic. The sound stage impressive for an amp this price, and once I had the tone controls dialed in (two pips down on the bass, three up on the treble for me!) the tone and texture are equally good. The tubes really do add a touch of warmth and soften the digital input (I’m looking forward to doing some tube rolling too). The Airplay is so good I’ve not even tried the the Bluetooth. One notable thing that should be mentioned is the power saving click. When the amp loses signal for 10 seconds in any input, there is an audible ‘click’. This can be off putting at first, but as I understand it, it’s a mechanism to prolong the life of the box. After a while I don’t even notice it, just know that it’s not the unit being defective, it’s by design. Oh and it’s even got a remote! Pretty basic, but does the job. Over all I can’t sing the praises high enough for this little amp, it offers fantastic bang for the buck and even looks super cool. The VU meter is a nice touch, though I never listen loud enough to get it jumping much!

The media could not be loaded. I got this Amp for my mobile editing/entertainment bay. I needed it to be relatively small, powerful and have the ability to receive clean SPDIF signal, and this beautiful amp fits the bill. I like that I can control the bass and treble right from the front console. I am so happy with the way it processes sound. This is a winner gadget a audiophile like me can appreciate. The VU meter is so fun to watch fly. I absolutely recommend this product to anyone that needs one.

Good build quality and looks good as well. Drive my speakers great despite its small size. Comes with a good power supply (not a wall wort). Noise levels are very good, no excessive hum or hiss. Remote works. Bluetooth works.My only complaint is that I would have like a dedicated power switch and would like to have had adjustable gain on the VU meter.
