Wow, I don't know what happened (did not turn the computer on this weekend - just playing with the Denon and Axiom speakers), but I hope it was not my original post.

Anyway, I tried the bi amping and JohnK was right, I could not tell much difference. And thanks pmbuko, I was able to select the ceiling speakers for the rears and could get the 7.1. The axioms do such a great job that I really do not notice the ceiling speakers.
