Plenty of Power/Awesome Sound!
This is an amplifier that punches way above its price range and size. It is well built and looks great. It has tested very well for its technical performance (see Audiosciencereview's test report) and that is reflected in its sound performance. I am using it to drive Elac 6.2 Debuts, and it has plenty of headroom that I will never need. And I am using the 32V 5A power supply option, which means I am barely powering it to just over half of the amplifier's output potential.The amp runs very cool when driving my Elac 6.2s. I am using a Schiit Modi 3+/Magni 3+ stack to feed the amp.To take the sound to the "next level", I tried several op amps including one that was recommended by an engineer at Aiyima in a paper called "The OP Chip Can Use on AIYIMA A04 & A07". Obviously I tried the NE5532 that comes with it. This sounds great as it is. I tried the LM4562NA. This offered some improvement. I did not leave this one in long enough to characterize it, only that the sound was "better". I tried the OPA1656, which I feel actually degraded the performance. The op amp that made a significant improvement is the OP275GPZ. This is one that is recommended by the manufacturer as an op amp that offers "Better resolution, low frequency and sound field than NE5532". I found this to be very much true. I think by "sound field" they mean "sound stage" as that really did open up. There is a clear improvement in resolution. I also found the treble to be more refined which was not expected from the description from Aiyima. And it also took "boxiness" out of the vocals. I don't know if the boxiness originated from the amp or my speakers, but the 275 cleaned up the vocals and they are now simply excellent. If op amps were free, I would try some others that the paper recommends. But given that they are not, and I feel I have hit on one that yields a big improvement, I am done searching. Any others will either most likely be a step back or just offer marginal additional improvement.This is a great amp as it ships. Since the input stage op amps are socketed, you have the opportunity to "roll" them to adjust the sound to your liking as I described above. For me, I found the 275 to be a phenomenal choice.Based on my experience, I highly recommend this amp!

Reasonably cheap, takes up little room, sounds great!
I bought this little amp, a Bluetooth receiver, and a powered subwoofer so that I can put my pair of Blueroom Minipod speakers to use which I had lying around. I mostly use this setup for playing Spotify from my iPhone through Bluetooth. I got the AIYIMA A07 on sale for about $65 and the Bluetooth receiver (BlueDento B1 aptX HD Bluetooth 5.1 receiver) was about $35. I also added a 10" powered subwoofer (Monoprice SW-10 150 watt RMS) which purchased from Monoprice for ~$90. The setup gets pretty loud without any perceptible distortion (with volume turned up to about 1/2 way to full) and the sound quality is surprisingly good! It is less than 300w per channel because of the power supply that I have. But, it is plenty loud, believe me.The thing that I like the most about my setup is that the whole setup takes up no room at all and is out of the way so that you don't even notice it. It occupies a tiny corner of my desk and the speakers are hanging on the wall with the subwoofer under my desk. I am loving the sound! There is no sibilance. I can't believe that this cheap little setup sounds so good! I mean audiophile quality sound! The sound staging is fantastic! There is a lot of realism. With my setup the frequency spectrum is well covered from about 50 hz - 20khz. When listening, I sense a lot of space between individual instruments and voice and near absolute silence when there is no music content. I leave it on 24X7 because it doesn't use much power when there is no content and whenever I want to play music, I just turn on the Bluetooth on my phone or laptop and off I go, instant music. I also control the volume digitally from my phone or laptop as the Bluetooth transmits original digital content and the DAC which is inside the Bluetooth receiver does the digital to analog conversion so, be sure to get a Bluetooth receiver with a good DAC chip in it. I have the Berwyn chip which is pretty darn good.

This amp flew past my expectations, really impressed
I've only used higher power receivers and stereo amplifiers in the past. I am amazed at how well this little Class D wonder manages to power my Klipsch RP-600M. Runs cool, has ample power with its stock power supply to well exceed my listening comfort without sounding distorted. The aux output works great as a subwoofer out in this model (apparently in preceding models, it would not raise and lower the volume of the aux jack with the main volume knob, but it does now, really well). We've watched movies and the impact and lively sound is all there, it can keep up with any music or gaming we've thrown at it too. In no way has it been deficient and I'd dare say that it's as good as the solid state amps I've relied on in the past. Shaking my whole thinking up here!I am sure having reasonably efficient speakers helps - from what I've read its real output with the stock power supply is around 75-80W max per channel with the stock power supply. But with these RP-600M in an indoor setting that's extremely loud and sounds great. It's easy to set up and integrate into your system, too. I'm using it with a few Schiit Audio units, namely their Modi DAC, Loki Mini Plus EQ, and Magni Heretic preamp, which gets my signal ready to go and gives me control over the tone and level. I don't know how it would sound just coming off of my PC's sound card, but like this, it's been awesome.I can't speak on its long term reliability yet but I'll check back in a year or so and update my review. Assuming that it holds up well, I will probably end up getting another for another room!
