I've tended to try and stay out of the bi-wire threads, as they usually end up getting a tad ugly. Personally I've never heard a difference with bi-wiring, and from what I've read, I shouldn't.

Bi-amping, I'm curious about. I'll soon have my Odyssey Stratos amp, and my Rotel RMB-1075 is going to have a couple of free channels. Is it possible/advisable to bi-amp my M60's with the Odyssey and Rotel amps? If so, how would I do it?
