Thanks to all for your feedback and insight!
I had started out to build a nice home theater and I've ended up going through an audio renaissance! The M60s are MUCH better for me. The clearer midrange is awesome. They do go lower than the 50s and perhaps because of the difference in driver configuration, with the dedicated midrange, they just seem to produce a more dynamic range (at least that what my rapidly changing brain and limited vocabulary seem to describe it as).
Well now that I'm so happy with this upgrade, I'm thinking I may want to move up to the VP150!
