If you really want to maximize stereo performance, buy a used $250 AVR receiver but get a 2 channel stereo amp and a 2-channel preamp ($2500 combined) with HT pass through. I can tell you from experience, there isn't a 5+ channel amp that can compare with a two channel amp for the same price (or even less for the 2-channel amp).
This is by far and away the best way to go. There isn't an AVR Receiver that will even come close to sound performance for music taking this route.
