Hi all, I'm considering buying a pair of Axioms for my new apartment and had a few questions.

1. How does the M50 compare with the M40 on the one hand and the M60 on the other? I've gotten slightly variant information.

2. What would be minimum listening distances be for all these speakers?

3. I was thinking about placing the speakers like so (O = chair, X = speakers):

Is that a reasonable thing to do?

4. How much does return shipping from the US usually cost? (I'm in the DC area.)

5. Is there anyone in the DC area who'd be willing to let me listen to their Axioms (any model)?

Thanks!

David
