To chesseroo & spiffnme,
Thank you both for your input and insight. I have realized that what my brain thought I liked in sound and what my ears actually preferred were not one in the same.
Spiffnme, as you said, I think I do prefer more detailed speakers and my intial purchase was based more on horror stories about _overly_ bright speakers and the M3s I liked were described as more laid back, so I thought a more laid back tower was the right match. I hadn't accepted that I do prefer the detail and crisp upper end that only brighter speakers provide. I should pick up the M60s tonight and hopefully my brain will be much happier.
I think either the M60s or the M22s are probably a better match for me and a sub is probably in my future either way. Thank you both for your help.
