Hi, Sheba

Welcome! I can only add one thing-and that's to answer only what's my opinion on one part of your question: "I'm thinking M50s...hows that sound?"

I think they sound great!!

I can't talk about the VP100, as I'm currently, and have been for years, been using an inverted M3 as center.

The M3s are why I have M50s-when I needed larger speakers, I went for the speakers I was most familiar with; my beloved M3s!!
