Axiom Home Page Forums General Discussion Stereo just got M22s, do I add sub or switch to M3?

One other thing I'd like to point out is the effect different receivers have with the M22. Originally, I had the Sony STR-DH500 ($160, 100 watt), then I sent it back and bought the Pioneer VSX-21TXH ($630, 110 watt). The difference in bass response between using these 2 receivers is like night and day. I get a much fuller sound with the more expensive Pioneer.

But I reread your post and the Denon you're using should have plenty of power.
