Axel,

It sounds like you're on your way to building a fantastic system. While it's important to hear other people's opinions on which is THE way to go regarding speaker configurations, you have to remember that you also have to live with those speakers. If I had the room for them, sure I'd have 5 M22tis all the way around. That's just not practical.

I think the Axioms might impress you more than the B&Ws did.
