AIYIMA A08Pro Bluetooth 5.1 TPA3255 Mini Power Amplifier 2.0/2.1 Channel 300Wx2 (4 ohm) HiFi Stereo Amplifiers Class D Digital Audio Amplificador VU Meter Amp with Treble and Bass Control

The media could not be loaded. Pretty good amp for driving passive speakers , this is solid option for price point . It's a class D amp which allows small size factor and as per the specs remains quite cool under continuous load . Very useful to just plug it and place it on a small desk .Has 3 inputs - 1) RCA ( which can be used to connect to pc via 3.5 mm pin )- 2) Aux Input- 3) Bluetooth ( always on )Sound gets very loud at 70 % to be uncomfortable to listen to but still doesn't distort a single bit . I haven't tried to push the knob to 100% , even with my 60 w 8Ω speakers . Now i don't have a fancy pair of speakers , and I haven't heard some super costly systems but from what I experienced from this amp is really good . It gives out some frequencies I didn't know existed in my fav songs . My sources are Youtube / Spotify and some bootleg 192 Kbps songs and listening env is medium bedroom with no sound treatments . Also listening to dialogues in tv series with this and experience has been pleasant . Treble / bass knobs are pretty much analog equalizers and can be used to tune as per user preference , works well .This unit has same chip as A07, TPA3255 Chip , and if you are constrained on money or simply don't need bluetooth go for it both should sound the same . Quite frankly it was impossible to tell fi the sound was coming from wired source or bluetooth .I bought this for phone connectivity , which quite honestly is very convenient . Although bluetooth can't be turned off , one can remove the antenna . Also a very cool feature is knob turns blue if the source is wireless and red if source is wired , although prioritizes bluetooth over wire when both are connected , feels like should be opposite .Default power supply 36W /6A ,can easily power up-to 100 Watts 8Ω passive speakers on each channel and with extra supply it can go upto 300 but that's untested since i don't have speakers of that range . Besides this is really cool way to keep price lower .About the 2.1 part technically it can power a passive woofer probably even an active one but the bass is not powerful enough . But for me that's a blessing since i dislike heavy bass . On side note it has a companion t8 pre amp available but honestly most modern motherboards / tv should have good enough sound cards to drive mid range speakers and would be unnecessary purchase m unless one listens to fully analog sources !Fosi and other brands offer almost same products at this price range maybe a bit less output and honestly they are all same . I chose this because of product design and that analog VU Meter ! It's really cheesy but nice to look at .I have hooked them to my pc with some low cost speakers and am amazed , next stop decent speakers :). Buy it if you can , can't really complain let's hope it lasts long enough!

I bought this amplifier to listen hi res music. I paired it with a dac to listen hi res music. I have say that the audio quality is really good atleast in my case, im using speakers outsourced from a Sony bdv home theatre system, I've tried connecting another pair of very old speakers from a Sony home theatre system. Both sounded really great. Till date I didnt turn my volume more than 50 percent. It was that great. I've paired it with a dainty 10 inch subwoofer. Overall quality is also very good. The scroll knob feels very premium. The overall build is also very sturdy. The main area where it shines in this segment is that it has ldac support which no amplifier has in this segment. That was a main thing that made me buy this amplifier as I'm using apple music I can stream hi res music wirelessly. The only con in this amplifier is there no source switching which I often find annoying cause if a device is connected to the amplifier via bluetooth, u can't disconnect it from the amplifier. Thats the only annoying thing in this amplifier. Overall bluetooth connectivity was also very stable. Didn't face any signal drop or fluctuations. Overall its a compact size powerhouse that can satisfy your music listening 💥

No issing sound. Very cute. Value for money

The media could not be loaded. I was using a good amp but I wanted more. And then I came across this baby beast. Superbly warm, authentic and powerful sound, great connectivity, seamless in everyway. And for such a great price. It has given new life to my KEF bookshelf speakers.

I have marantz AVR high end model. Listened many other AVRs also. In stereo mode and Dolby mode and dts mode. This is pure genuine and genius sound. All you need apart from this device is a pair of good sounding bookshelf speakers. Thanks Amazon.

Worth every penny just go for it

Sound quality not good and heating issue and not working properly.Please upload details in amazon what are given in box .Thank you

Amplifier is adequate. Not of audiophile quality but close to a good class AB amplifier. It drives my BES speakers well.
