The fact that this is ac based is alone a big plus. Sound quality is very good. Remember to halve the promised power values unless you like great amount of distortion :) Read the chip data sheet for more info. This is more of a normal amp than subwoofer type. For subwoofer use there are better, purpose built ones. Pleasantly surprised as I just wanted to know if these cheap amps are good for anything serious related to audio sound quality. I'm Pro audio engineer and I buy amps @ 400-1000€+ price range. Normally.

The first time I have connected this board (24AC 0 24AC), I had... smoke and "fire". R6 and R7 were black. I replaced both (10 ohms each), and I've got smoke again. I decided to remove the heatsink to see the IC chip and... surprise!!! The pin 23(VDDP2) is not there!!! How is possible this board passed the final quality tests??? This kind of problem never happened before in Banggood shop.
