Default TAS, TPA, or max?

Hi guys, i got some samples from TI and maxim, TAS5611, TPA3106D1 and MAX9709/04

I want build a pc amplifier, about 50w, i just tried the TPA whit a board that i found here in the forums, but it didint work properly.

NOw i got a dilemma, what i build? i want a hi fi amp but idk who of these are better.

TPA is easier but TAS is more powerful. TAS requires two power supplies (PVDD and VDD) whereas the TPA only needs one. You're going to need a hot air rework station or something along those lines to attach the TPA's thermal pad to the PCB though.

You say you're making amplifiers for PC speakers?

Yes, for pc speakers, more than power i want quality but i think both are same.

I got a hot air rework station, its a portable one but it works in this case.

I already try to get ework the TPA whit no results, lot of distorsion and sometime dead silence.

Thats why i tend to the TAS, i want to use this pcb


Unless u guys got another pcb for the TPA.
