While the rest of the world marches on towards 6.1 and 7.1 surround sound, my lowly home theater is going to be permanently mired in 5.1 (No room for the rear channels). It seems even the mid-priced recievers are now all 6.1 (at least). Now then, since I can buy seperate power amplifiers that put most any reciever to shame, I was wondering if the HTF had any suggestions for good used pre-amps (Cause I'm cheap). I'm not too familiar with the different makes & models of seperates, so humor me Pre-Amp requirements. *DD & DTS are required, PL2 would be cool but I can deal with PL1. *5.1 analog input (for SACD / DVDA) would be good too. Anything like this manufactured in the last few years that might be available off Ebay or Audiogon for @ $500? or am I asking for too much?
