I have also heard the VP150, and I can say that I much prefer the sound of two M2s over 1 VP150 any day.
Warms me heart to read that. I can hardly wait to see how the M2s sound as centers.
From what I understand, the reason centers are the way they are is to fit in tight spaces and look good. They are a compromise and a small pair of decent bookshelves will always sound better.
Some centers actually offset their mids and tweeters and are supposed to perform better, but they are taller and don't fit into a lot of stands.
