$2500 amp and pre/pro

Ok, my receiver just died. The good news I can now move on to separates and finally hear the full(er) potential in the rest of my equipment. The bad news is I'm off to medschool and, for the next several years, will redefine poor. I will be buying used off A'gon--if at all possible, I'd really like to stay under $2500 for the pair. Here's the rest of my system.

4 Vienna Acoustic Bach's
Rel Storm III sub
Pioneer 47a player
some crappy cambridge soundworks center speaker

Multichannel amps that seem to be in my price range are sunfire cinema grand, B&K, Outlaw I guess--though I don't like that option much--not really sure what else. Vienna Acoustics are warm speakers and I'm concerned that warm sounding amps might make them sound dark.

I'm really stuck when it comes to a pre/pro. They all seem to break the bank. Video switching is not crucial, SACD + DVD-A input is however. I'm also leary of processors that disable the sub in two channel mode. The Bach's are only rated to 38Hz (which I think is a stretch) and I really like to be able to use the REL to fill out the sound while in stereo.

Although I'm looking for a multichannel setup, this system will be used 90%+ for music. I enjoy two channel and multichannel alike. Movies come a distant second.

Any ideas are welcome. Thanks
