Well, I picked up the MAs last night. Unfortunately, I barely had time to set them up and hear a few songs before the baby had to go to bed. First impressions:
-the Rosemah finish is nice, but not nearly as nice as the veneers on the Gold series or on the B&W 804s.
-compared to the M60s, the MAs seem much smaller, but are only an inch or so shorter.
-they are not as sensitive as the M60s (big surprise to me).
-they sound remarkably similar, with the exception that the MAs are "softer" sounding and project a more recessed stereo image.

Hopefully I'll be able to set them up for A/B comparisons today and give them a more thorough listening.

Also, the MA manual is a joke - full of talk about biwiring, break-in time and other techno-babble marketing hype. Most surprising was how poorly the manual is written. Call me a pedant, but aren't the English supposed to have a better grasp of their language than ignorant Americans?
