Yeah, the timbre mismatching would bug me. I really want the M60's as fronts. But, the VP150 is totally throwing me off here. It has an obvious cut of bass at <90 hz and strong boost of treble in the high ranges. I really like a full size tower, so buying Ascend's center would deny me of a good full tower like the M60. PSB and Paradigm don't provide graphs. Grrr.
