I just wrote a lengthy post myself recently on our choice between Axiom and Angstrom speakers (the m60s vs Modulars).
Axiom M60s won and i've got them in my basement right now along with a pair of M22s which will head back in a couple of weeks.
Since you never had the M60s to listen you can chek out my post along with at least one other i saw recently posted as well (M50s vs. M60s i think).
However, if i recall correctly, not too long ago, someone asked for the difference b/w the M60 and M80 and Ian had replied that they sound virtually the same except the M80 can play significantly louder.
I wish i could find that darn post...
