AIYIMA A80 Power Amplifier DAC with PFFB TPA3255D2 Stereo HiFi 2.0 Channel Class D Bluetooth Amplifier 300Wx2 ESS9038Q2M Decoder with PC-USB Coaxial Optical TRS RCA Input

I’ve been using the Aiyima A80 amp since December 2025. Since my room is quite small, I decided not to go for the 48V/10A power supply upgrade, as I simply don’t need the extra output. Instead, I focused on a couple of upgrades that I’d consider “must-have.” First, Aiyima offers a display upgrade at no extra cost. I reached out and got one installed. It’s not a game-changer in terms of sound, but it definitely improves usability and overall experience. The second upgrade was swapping the stock NE5532 op-amps for LM4562NA. This was easily the best decision. The improvement is immediately noticeable—more detail, wider soundstage, and better depth compared to the original setup. There are plenty of amps across different price ranges, but the LM4562NA is a stable, obvious, and budget-friendly upgrade that just works. The Aiyima A80 is an excellent amp that I can confidently recommend. Just don’t overlook op-amp rolling—it’s not optional in my opinion, it’s essential. Enjoy!

Très bon ampli , les basses ,aigus et médium tout est bien en place , les voix sont très bien retranscrite . Couplé à des dynaudio émit II 10 qui demandent beaucoup de courant cette ampli Aiyima A80 s’en sort très bien et les alimentent sans problème . Je possède aussi l’Aiyima D03 qui est aussi très bon , l’A80 chauffe beaucoup comparé au D03 surtout lorsque l’on laisse allumer l’écran avec l’equaliser ou les 2 autres au choix disponible C’est vraiment la seule chose que j’ai à reprocher à çette ampli . tester avec d’autres enceinte de 4 olhms contre 6 pour les dynaudio l’ampli chauffe tout autant . Donc a voire dans le temps mais sinon je conseille vraiment çette ampli qui a un son excellent et qui vaut bien des amplis de class AB bien plus coûteux .

This is the perfect little amplifier for my needs. I play FLAC files that I have on my android tablet (connected via a OTG USB-C to USB-C cable) and it seems to drive the A80 quite well. Sound quality, to my ears is very pleasing, it's hard to fault this amplifier. The displays mimicking of analog style VU meters adds a nice touch. Don't let the low price and the class D config put you off buying this amp, it's a seriously good amplifier with more than enough power to drive most speakers to 'loud enough' levels. I have spent 10's of thousands on hifi gear over the years seeking the perfect sound.. never been fully satisfied with the outcome, so with this amp I settled for 'good enough' and I have been more than happy with my decision.

I have been a happy user of Aiyima A07Pro (it's going to my teen's bedroom), so I am not new to the D-Class amps party and knew what to expect. I am pleasantly surprised though - the A80 elevates the experience to another level. Sound quality Aiyima, from the times of the first A07, has always impressed with sound quality. Independent measurements of channel separation, distortion and noise level show excellent values, but the load dependency always lurked in the shadows. Fear no more - the post filter feedback loop tackles those as well. In the end you get a pocket amplifier with reference quality. Amplifier has enough precision to drive speakers at a lower volume, but there also is enough punch in this little guy to shake even my relatively big room. Features and quality Not only is the sound excellent, but the overall feel of the amp is great. Build quality is stellar - very nice weight to the unit, good haptics when turning the wheel. The display is big and clear as well, and it can get very bright too. The multitude of inputs is very impressive. You have regular RCA, as well as TRS for symmetrical analogue connection. There is coaxial and optical SPDIF. There is a subwoofer out. There is a good implementation of Bluetooth and my personal best - USB-C. Super Easy to Use with my phone! The most awesome thing is how easy it was to connect from my phone. Less and less phones have analogue audio output and it starts to become a nuisance. Not here - Bluetooth works well and thankfully is not visible unless you select BT as input (the nasty neighbor will not connect to your amp uninvited). I am however super happy how the USB connection worked. I used an ordinary USB-C <-> USB-C cable to connect - and without any fuzz, configuration or going through options - fantastic sound from the speakers. No BT losses, no noises from the cables. The digital sound goodness in all its glory. What not to like? There are a few very minor issues though. Two actually. The menu navigation is a bit awkward: there is no dedicated BACK button, and you have to double-push the volume dial to go back. You don't use it frequently, but when you actually have to, it is weird. Second issue I have is that the display won't turn off completely. You can turn the brightness down from 100% to 10% in 10 steps - so it is not annoying at all. An "auto-off" mode would be nice here though. Summary Overall, the Aiyima A80 is a great little amp that really delivers. It sounds fantastic, looks and feels solid, and has all the connections you could want. It's easy to use, especially with a phone, and packs enough power for serious listening. Sure, the menu could be easier to use and it’d be nice if the display could turn off completely, but those are small complaints. If you want a powerful, great-sounding amp without spending a fortune, the A80 is a smart buy.

Poca spesa tanta resa, preso per gioco, premesso che ho anche wiim amp pro, casse monitor audio bronze, ho sostituito operazionali e alimentatore ed migliorato ulteriormente, bello Ariosto, alta in evidenza, forse il basso non è così veloce e articolato come il wim, ma timbricamente piacione, alla fine tra amp, alimentatore e operazionali arrivi a circa 320 euro, direi comunque ancora ottimo, per chi ama gamma alta dolce ariosa e in evidenza consiglio, non aspettatevi potenza devastante, fa il suo al limite di sopportazione vicini...
