I am telling you Rich you should seriously give the M5s a try. I haven't heard them against the v4 M22s - only the M3s - but I expect them to best the M22s in every way.
I'm not convinced; on the other hand I'm not unconvinced either. I have M2s, M3s, M22s (v3), and M5s; and I go back and forth whether I like the M5s better than the M22s. I like the M5s, but I think the M22s are cleaner/crisper. For me, to keep it short - I like the M5s better for a home theater setup, but I like the M22s better for a purely music system. (But that's not exactly accurate either, as sometimes it depends on the genre or recording.)
My advice would be to demo both at the same time and keep the ones you like better most of the time. (Not sure how Axiom feels about that.)
