I had to read this thread twice (and the one referenced in the first post once). Yhe m2 sounds better than the vp150. wow.
I get that people are saying the vertical arrangement is better - but what about the fact the vp150 has 3 more speakers? I guess they don't come into play?
I am seriously considering picking up some mains and a center in the next month or so. That is about a $260 savings over a vp150.
