Wow!! You have been busy, haven't you
Looks like you're getting a pretty good idea of what it is you're looking for!
Speaking candidly; I have heard absolutely none of the speakers you've auditioned, nor either of the Axioms(M60) or Rockets(550)you have questions about
I have read that the M60 sounds similar to one of the B&Ws you didn't review, so that dosen't help much
There are, of course, tons of posts that talk about the sound of the M60s as "We" hear it that you can look over while we all wait for a local review of the 550s.
The M60s are the floorstanders of choice for the majority of Axiom owners who opt for an eight ohm speaker, so it's a very well reguarded device!!
Happy Hunting!!
Rich.
