The Axiom guy wasn't trying to just sell you the bigger speakers regardless of performance. Good as the M22s are, the M60s really are better -- I had both. But IMO the difference is more meaningful for music than HT. If your main focus is HT, M22/VP150/QS4 + a good sub is fine, and it's no slouch on music either.

That said, after getting Axiom speakers some of us end up listening to music more than we envisioned, it just sounds so good. Although M22s are good, M60s are better for that, based on my experience with both.
