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

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.

I've been exploring various integrated amplifiers to enhance my audio setup, and the Aiyima A80 caught my attention with its impressive specifications and affordable price point.​ I’ve previously owned Aiyima products; the A07 Max and A07 Amplifiers, which are superb sounding, especially at their price point. Build and Design The A80 boasts a compact and sturdy build, measuring 155 x 123 x 41mm and weighing approximately 850g. Its front panel features a vibrant color display with customizable VU meters, adding a touch of retro charm to its modern design. The volume knob feels solid and responsive, doubling as a menu navigation tool. While the display is clear, it might be a bit small for larger rooms. Connectivity and Features One of the standout aspects of the A80 is its versatile connectivity options. It includes USB-C, optical, coaxial, RCA, along with Bluetooth 5.1 support featuring AAC, SBC, aptX, aptX-LL, and aptX-HD codecs. The inclusion of a 12V trigger input allows seamless integration with other components, and the AUX output can connect to an active subwoofer or a second amplifier. ​ Performance and Sound Quality Equipped with the TPA3255D2 amplifier chip and ESS9038Q2M DAC, the A80 delivers clean and powerful sound. It supports high-resolution audio up to PCM 32bit/384kHz and DSD256. The PFFB (Post Filter Feedback) circuitry enhances performance by reducing distortion and improving frequency response. In my listening tests, I would say it is equal to, if not better than than the A07 Max. The A80 provided tight and controlled bass, smooth midrange, and crisp treble. It handled various genres with ease. I have a 2.1 system (see attached picture), which isn’t easy to drive with full range open baffle mids and highs, and a sealed bass box, but it handled all these drivers with ease. The soundstage was immersive, with precise imaging that brought vocals and instruments to life. ​Bass was tight and controlled. Additional Observations The A80 includes tone controls for bass and treble adjustments, allowing for personalized sound tuning. It also features replaceable op-amp chips, providing opportunities for further customization. I would always recommend op-rolling for tweaking the sound - I’ve tried OPA1612 and MUSES and they all add to the enjoyment. You can find op-amps on Aliexpress for a few pounds from reputable dealers, so it is always worth a look. While the unit can get warm during extended use, it's not excessively hot. The absence of an HDMI input is a minor drawback, but something I personally need. My list of wants for future Aiyima products is Spotify Connect and Wifi, for mobile operation. A high and loss pass filter would also be game-changing. Conclusion The Aiyima A80 stands out as a versatile and high-performing integrated amplifier that offers exceptional value for its price. Its combination of robust build quality, extensive connectivity, and impressive sound performance makes it a compelling choice for both audiophiles and casual listeners looking to elevate their audio experience. I have yet to find an Aiyima product at its price point that isn't a suitable value, and the A80 is currently the pick of the crop for an integrated amp with a superb DAC and one of the latest Bluetooth chipsets. Highly recommended.

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 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.

Lovely compact amp that packs a punch with a nice looking display, I got two linked together one showing the twin SWA meters & one displaying the spectrum analyser. They sound splendid wired up to my old 100W AE & Mission speakers & I can run my active/powered sub.

Aiyima A80 works fine. I have connected to TV using Digital Optic and paired with well known ribbon Tweeter based Quad S2 Speakers. Sounds good. I will be replacing Opamps (Sparkos) soon. Very good DAC. Digital VU meter is very good! Value for money. Under £200 this is the best. Having HDMI / USB player would be beneficial but Aiyima has Digital Player DP1 for this purpose. Worth buying.

A80 & 48V/5A power supply, connected to Dynaudio Emit 30 floorstanders (4 ohm, 88 dB sensitivity). With Wiim Pro Plus streaming Qobuz/Tidal the sound quality was great, the musicality, the fluidity, the control, the balance were there to enjoy. But within one hour of listening at moderate level it became very hot while the vu meters went beyond the 0 mark, meaning full volume, and the sound coming from the Dynaudios was similar to my class AB integrated Bryston B60R (100wpc in 4ohm) at 9 o'clock volume position and reminded me (unfair comparison) of the sound level of my old McIntosh MA6800 when showing 5-10 watts on the blue vu meters. I know that there are many factors in place: sensitivity, gain, current etc but it is ridiculous to quote 120wpc in 4ohm when the A80 becomes a toaster at a much lower level. It can be recommended at most as a tiny desktop amp with good nearfield high sensitivity speakers. To make things worse a Douk Audio T6Pro hybrid amp sounded similarly great but the volume knob was at 9o'clock being just warm. One note, I matched the quoted sensitivity for 0 mark of each amplifier (2V for the A80, 775/800mV for the T6Pro) using the audio output level control of the Wiim Pro Plus. My experience conclusion: FRUSTRATING and I returned it within the next two hours.

What an amazing, powerful little piece of tech. Paired it with my also new Polk monitor xt15 and a presonus eris sub 8 and I'm very very happy. It looks awesome and I looove the AV meters!
