@fredk: Did the M22+sub sound exactly like the M60s for real? I just ordered the M60s and was contemplating the HP version over the standard version. Right now my system has some old Sound Dynamics 6/5" drivers (bookshelf model) and a Velodyne 8" sub. I'm hoping the M60s will sound as good, if not better, in straight two channel operation (no sub), as I want both systems in my living room (wife permitting). If, as you say, the m22+sub combo sounds the same as M60 without sub, I'll be a happy camper. My room is small - less than 1100 cubic feet.
