I had the chance to audition both the M22s and the M60s.
I stated some of my short impressions here if you are interested.

As an addition though, i've found the M60s definitely need more room to get the imaging to work right. At the present time i sit 8' from the speakers and this is just too close. I wish i had about 10' or more.
