What's everyone's opinion about which receiver sounds best with Axiom speakers? I'm trying to choose between Denon, Marantz, Onyko or Harman Kardon. My price range is between $500 - $800. I'm also looking at two different speakers for a home theater set-up. My room's 16X23. Would M22's, with a good sub do as well as M40's or 50's? I listen to 50% music - 50% home theater. Thanks for the input.
