AIYIMA A80 TPA3255 Bluetooth DAC Amplifier 300W*2,PFFB & Digital VU Meter

I have been a fan of these class D amplifiers for a few years now and mostly they keep getting better and better with each new release. I spotted a few online reviews for this new Aiyima A80 a couple of weeks ago and thought that would make the perfect Christmas toy to play with and I am mostly very impressed. So, in summary what you get with this class D amplifier that makes it different (and better than other similar recent offerings from Aiyima, Fosi Audio, Douk Audio and others) are the display with VU-Meters and a high quality built-in DAC. You also get internal PFFB circuitry which helps guarantee a consistent reference sound signature no matter what speakers you use - I am currently using a mostly pretty hard to drive KEF LS50 Meta's with this A80 and while it gets a little warm when driving this speaker to loud 80+dbSPL - it sounds great paired with a WiiM Ultra which is separately providing Room correction and bass management). The in-built DAC is pretty excellent specifically it is the same ES9038Q2M that is in the WiiM Ultra and other similar high quality DAC / Preamp's so there is no reason ( other than maybe the lack of HDMI ARC inputs ) to feel like you are missing anything with this DAC. But the display is probably the star of the show here with the A80 and while it's small and would be hard to see across a room it works very well. I included a video showing the display showing a few of the VU-Meter options with the WiiM Ultra screen for comparison it works very well. Other features which I do like (and work well with pre-amps / streamers like the WiiM Ultra) are the inclusion of a trigger input (so the A80 will go into standby automatically when not in use), the optical and coaxial inputs also work great with streamers as digital inputs. The USB connection works with my iPhone (and my Macbook) and includes lots of high res connection options - I have included a screenshot. Finally the inclusion of the RCA and TRS inputs as well as bluetooth provide a lovely upgrade path I think for a first time buyer of a class D Amplifier. Maybe start with bluetooth and the RCA, then get a Streamer like the WiiM Mini or WiiM Pro and use their Optical outputs (as both those streamers have poor DAC's so digitally connecting) and you still have the option for balanced inputs (though the TRS input option is less popular balanced connection than the more typical 3-pin XLR's cable inputs). I think you could have the following inputs connected with this little amplifier - turntable via RCA, PC / Mac connected via usb, a streamer like the WiiM Mini via optical or coaxial, your mobile via bluetooth and still have the TRS connection for later updates with some balanced audio equipment. Overall a great and fun amplifier.

Had it four days and so far, so excellent: punching way above it's weight, especially so far as value for money is concerned. Sounds _very_ good out of the box, yet definitely gets even better after a day or two's running in. It does seem to need any source turned up to near max, and even then you'll be using the top 30% of it's volume range (though this could be partly due to my source devices, or something to do with the A80's auto adjusting pre-amp gain). Doesn't affect it's usability at all, it can still go room-shakingly loud driving Mission Elegante E83 speakers in a 26' x 15' listening room. Also sounds very good with a pair of LS3/5as - sweet, clear and excellent sound-staging. As other people have noted, there is some hardening of the mid-range and upper bass at high volumes, but I do mean VERY HIGH. At normally high and medium volume this effect just isn't there and the character is very clear and musical. Comparing it to my re-capped Yamaha CA1010 it's not quite got that sense of effortless power and liquid clarity, but has got quite a similar, very neutral and natural character. Also the Yamaha was £1,000 new in 1978 and will still fetch over a £1,000 now, so hardly comparing like with like! The fact that it can reasonably be compared at all shows that it's pretty special for the money... One other thing, I don't find mine gets super hot - very warm, yes, but not so hot that you can't easily rest your palm on it (and I tend to play my music at quite high levels). Maybe the circuitry has been updated in some way to improve this?...

This is a great wee amplifier however the documentation could be much better. Had to contact support as the trigger wasn't working and actually locked up my Denon amplifier requiring a factory reset. Up on further testing I found that the trigger in is a STEREO plug despite the standard being a 3.5mm mono plug. Denon specifically state in the manual not to use a STEREO plug but MONO. Plugging in a MONO plug will short circuit the 12v trigger out of Denon when the other end is connected to the Aiyima trigger in. I ended up cutting one of the MONO plugs off and fitted a STEREO plug for the Aiyima trigger in side. The ground was wired to ground on the STEREO plug and the tip wires to the tip of the STEREO plug. The middle ring was left unconnected. Before reconnecting it to my Demon I applied 12v to the MONO plug and the Aiyima A80 did switch on. Sound quality is great for an amplifier this size although the Bluetooth input levels aren't as strong as the rca inputs. Would recommend the amplifier but please take care if you need to use the trigger function.

I bought this because I've got some Gale Bookshelf speakers, and I've been using a Nobsound little amp to go from USB to Banana plug. It's been good. But the form factor was a bit crap, with the usb coming out of the front and the interference from the static of moving the volume nob. It had done it's time basically. Spent ages looking for something. Found this. Thought sod it, I'll have a punt. Plugged it all in. It powered on. Good Start fired up spotify Cuddly Toy Roachford. Full blast And you could hear it clearly, no distortion, just clear Roachford (you've got your foglights on) It's currently running away at 192Khz massaging my ears. I've spent years listening to the same songs over that nobsound. I can hear the difference over that. honestly, can't complain at the moment. Haven't tried any other inputs. I'll caveat that. but overall first impressions are brilliant.

Well packaged feels and looks quality . Used with my old Samsung j6 mission 771 speakers and Spotify premium sound quality is very good. The Amp gets quite hot so be aware it is normal though. Main downside my hi Fi system with over 1000 cds is redundant!

Looks good on paper, really great specs. That's only half the story. This tiny little box is probably a superhero of the mini amplifier world! This thing rocks but strangely it took a while to get my ear in, right out of the box I wasn't expecting miracles. The amp took about 5 hours to break in and really sing, it first it was a little cold sounding almost thin and cold. But it is worth being patient and giving it a chance to shine. And shine it does. The Bluetooth connection sounds good 👍 but when connected to the PC with the supplied usb lead it really works well. The onboard dac is transparent and lets your music breath and the class d amplifier just sings. I've tried it out with book shelf speakers and large but old Sony floorstanders and it just gets on with it, is capable of skull cracking volume with the 48v 5amp. The remote is a bonus and the onboard display is great, makes tone control adjustments easy along with input selection.

Great little amplifier, plenty of inputs. Just a pity you have to max the volume to get any response from the vu meters, otherwise excellent product.

I'm running these into monitor audio bronze 2 speakers the Bluetooth is spotless haven't tried the other ports . Sounds clear really good clear only bad is it runs like a toaster. If you run a fan on the side it cools down but it is toasty as hell.volume at 50 or 60.sounds I'll add a video

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!

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.

Dopo 10 giorni di utilizzo posso confermare che è un ottimo acquisto! Collegato a due casse passive JBL Control 25t da 30w l'una. Audio pulito, regolazione personalizzabile e tanto volume. Personalmente l'ho impostato a +5 di Bassi e lo trovo perfetto. Esteticamente nulla da dire, pulito ed essenziale. Amo la possibilità di poter cambiare la grafica dello schermo, dalla più classica alla più moderna. Unica pecca, se così la si può chiamare, è il fatto che dopo ore di utilizzo inizia a scaldare un pochino, ma ciò dipende molto dalle ore di utilizzo e dal volume impostato. In futuro collegherò un subwoofer attivo, visto che l'amplificatore lo permette grazie alle sue infinite porte sul retro. Dimensioni compatte e design minimal, tasto del volume reattivo e fa percepire una buona qualità costruttiva. Il telecomando è un plus anche se con il tasto del volume si può navigare in tutto il menù. Sulla propria postazione da un valore aggiunto e non risulta per nulla un ingombrante, cattura subito l'attenzione dando un tocco di Design alla postazione.

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.

Increíble sonido en un espacio tan reducido. Conectividad, calidad, precio, sencillez... no se puede pedir más por menos.
