I just upgraded my M22's to M60's after using the M22's for about 5 years. While I do feel I gave up a bit of midrange clarity in making the switch, I'd have to give the nod to the M60's. Just an all-around fuller sound than the M22's, while still maintaining the true Axiom sound that I love, but adding a nice touch of "warmth" that I think I was craving a bit in my front speakers. One cannot go wrong with the M22's (as long as you're using a sub), but I am glad I made the switch to the M60's. I'm still using the M60's paired with my SVS sub.
