I'm curious as well. I've never heard MWTs and this should be the most informative comparison that I know of.
I anticipate the 100s will deliver a sound that is essentially similar but has more authority and meat on the bones, like other much larger, and more expensive designs in a larger room might, at higher, more realistic listening levels, similar to what I have heard in comparing my 100s to Walsh 5s in both my smaller and larger rooms.
For near-field listening at more moderate volumes, I'm not expecting Rebbe will hear much difference worth getting excited about.
Rebbe, for an apples and apples comparison, be sure to compare the standard configuration MWT drivers, not the juiced top end versions that John Strohbeen rigged up for you, if you still have them.
