I have skimped through the heated discussions regarding the 3802 w/ amp vs 4802 w/o amp. But in any case will an amp improve sound quality in any case even if I have say the 5800 or 49tx? What amps would be a good place to start/good for the money? Besides outlaws. For HT purposes a 2 channel amp would be enough right? I understand that 5channel ones can get really expensive.
