Dave,
I thought I would make a few comments, since I was an M22 owner for a couple years before I made the switch to the M60s.
As has been mentioned, the M60s are a bit lighter in the bass department than I was expecting. I usually listen to them with my sub enabled anyway, so that isn't an issue with me. For lack of a better way of putting this, I liked my M22s, but I always felt that I needed to upgrade. I fought off the urge for as long as I could, using the rational that the M22s+sub is probably superior to the M60s alone. While that might be true for some, for me the M60s were the speaker I had been looking for all along. In the past 2 months I've grown quite fond of them.
