In reply to:
To "No solidstate amp will make M22's bass "tighter" or "punchier"..." I just have to disagree. When I switched from my Onkyo receiver to my Rotel gear, the only clear difference was the bass becoming exactly "tighter". No, not a HUGE difference, but it was noticable. Curtis (Mr. Ascend) brought his 340's to my place and the first words out of his mouth were the fact that his Ascends bass was "tighter" through the Rotel gear than through his HK525. (And YES we were of course listening to the speakers sans sub)
I agree with spliffnme here because there's the whole concept of damping factor. The higher the damping factor, the more control that the amplifier will have over the driver, and that can help for tightness.
