For my Axiom system I am looking at which receivers (that are under $500) that would be a solid addition to my setup. It will be a 5.1 system with no plans to upgrade to 6.1 or 7.1. I will be going with the M22-M2s as speakers. I tend to listen to music/movies at a moderate level, but occasionally like to play it somewhat loud. Is there anything to receivers being better or worse suited for the "brightness" of the M60/M22/M2s? Just wondering what would be a good fit for my setup. Thanks in advance.
