🔊 AIYIMA A08 TPA3255 Power Amplifier: 300Wx2 HiFi Class D Stereo Digital Audio Amp with Bluetooth 5.0 Support – Perfect for Speaker Home Theater System Review

This is the best inexpensive Class D amp I have ever heard and uses the highly acclaimed TPA3255 chip. It delivers 75W of pure continuous power per channel (300W at 10% distortion). I bought this amp based on the excellent review of the Aiyima AO7 which sits just below in the Aiyima range. This is a great sounding amp! Very clear sound, detailed but without a hint of harshness. Lots of weight in the bass range. For the price it offers a lot of value!

Sounds great, it's hard to imagine anything sounding this good until the price is doubled or more. All functions work great. Bluetooth works fine. The sound from the USB input is ok, I prefer the sound from my DAC over the RCA input on the A08, that's how I use it most of the time. Has plenty of power for my needs. I'd say it's similar in performance to an average amp at 80W per channel (8 ohm load). I tested it on my stiffer 4 ohm speakers and it drove them with no issues either. Rubbed the…

I've been using SMSL AD18 for two and a half years, driving SONY SSCS5 speakers on my desk via USB from Windows 10/Spotify. I wanted to see if a more powerful desktop amp would do it better and it certainly does! I based my purchase of the Aiyima on limited reviews of this unit, many reviews on the Aiyima A07 which uses the same amplifier chip. With this amplifier, the music is more airy, open and of high quality. Size and weight, it's about 3 times more than SMSL. It looks more industrial and…

SETUP The amp came in a box with a power cord and nothing else (except the Aiyima sticker) - no instructions, no warranty info*. Everything on the back is labeled, however, and I had no trouble getting it to work. I connected the device and plugged in the RCA jacks for listening. The volume knob rubbed the bezel slightly as I turned it, but I pulled it very gently and it slipped out by a hair's breadth, after which everything was fine. (*There is also no manual on AIYIMA website yet) IN USE /…

So I got the Aiyima A08 amp/DAC combo after hearing great reviews and measurements on Aiyima's A07 amp and the main problem with this amp is that the power supply is external. and this a08 is basically an all in one version with a high quality built in power supply that is more powerful than what you usually find on ebay paired with an old a07. This added USB and Bluetooth connections and a built in DAC. The IC amplifier inside is TPA3255 Texas Instruments, which is also found in the A07…

I tried this amp with my 8 ohm Polk S20 speakers. I'm so happy with the performance! The sound is clear, with rich bass and high frequencies. The quality of the human voice is also excellent. I tried all Bluetooth, USB and Aux inputs. So far I haven't had a problem, one user complained that the sound stops for a second or two in Bluetooth or USB mode. It doesn't have AC sound which another user complained about. I believe AC hum is ground referenced and you should always have a proper ground so
