I own one of those cheap Chinese Breeze audio TPA3116 (single chip so 2x50W) and I'm extremely pleased with the sound quality. It sounds "effortless" in the sense that it never seems to have trouble playing high dynamic range material (I play a lot of Mobile Fidelity CD's which have no compression).
I'm actually contemplating buying a more expensive TPA3255 model but haven't done so yet. Maybe someone can comment on the sound quality difference between the two.
