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

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 DesignThe 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 FeaturesOne 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 QualityEquipped 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 ObservationsThe 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.ConclusionThe 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.

The media could not be loaded. 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.

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.
