Best processor that is excellent for 2 Ch music

Or I should say, best surround preamp that has excellent 2 ch music capability. Basically I am 90% music / 10% HT, and I want to have a surround processor that is excellent for music listening (so as long as the processor has a 5.1 output I am fine, don't need too much features there).

What should I looked at if I want to spend <$1500? Would prefer a silver finish and gently used on A'gon is fine. What do you think? I heard about the Proceed AVP that should be great for 2 channel, another other recommendations?

Thanks.
