Thanks to everyone for all your advice. Having experienced the M3 I was pretty confident about Axiom. Today I spoke with Debbie, and she helped me with a ton of questions. My decision came down to Axiom, simply because I get more speaker for the money compared to Focal and Paradigm (even on sale), and I can get customer wood which is not offered on the others for any price. All your advice helped me decide, and with Debbie's final answers I've pulled the plug:

Ordered the M60s with custom maple real wood finish. She explained how the M60 would fit my room and listening style. Now I have more money left over for a decent power amp!

Thanks again... Really helpful community of owners here!
