Well, OK I was being a little glib. I think an 80w receiver might be marginal for the M60s. I am thinking that the soon to be released Yamaha RC-V663 will be a good match for me, particularly if it has the same power supply/amp section as the 659. That unit got very good reviews for its amp section at Audioholics.
I found it interesting that the folks at Crown were suggesting 1.5 to 2.5 times the speakers rated maximum power as a guideline for choosing an amp.
For the M60 that would be 300 - 500w!!
One of the things I plan to do when I visit Axiom is to see where my comfort level is with volume. OK, I'm pumped to go do some listening.
