I think the most simple, sure solution would be to get yourself a pair of mains that would blend well with the rest of your Axiom set-up (assuming you're happy with the other speakers). I have M60s and have found that some rock recordings sound good and others don't. Maybe the M50s would do it for you. The Monitor Audios would be better (more forgiving) than the M60s on those bad recordings. They may also blend well with the Axioms though I have yet to verify that with my little Bronze 2s. If you send me a dollar, I'll bring 'em downstairs for a listen and let you know.

BTW, GoodGuys was willing to sell me MA Silver 8s for $1250 with no payments, no interest for a year. Not too bad, though I decided to stick with my M60s.
