TPA3255 amplifier select

Thank you. It's very helpful. I will read it. :)
I'm now considering the Fosi V3 or the WONDOM BRU5. Both of them are stereo 300W TPA3255 amplifier. Fosi V3 looks very nice and the performance seems good... the BRU5 supports PC UI control and is really affordable...
 
If simple, high performing TPA is all you need, Fosi is unbeaten (with replaceable op-amps :)). The BRU5 is far cheaper and comes with built-in DSP, but the signal must go through the DSP chip (which may not be desirable from a SQ standpoint) and its internal build quality is just enough, not great.

You're spot on! When it comes to audio performance, going through the DSP can really degrade it. However, what I love about it is having the PC user interface for adjusting the EQ. I've heard that it's easy to start with and the software, I think it's called ACP or something like that, is free. BTW, the BRU5 is really much cheaper, only costs US$34 and the Fosi V3 costs US$58.
