Funny you checked out the B&W's. When I finally bought my M22s two years ago, it was the B&W 602S2 that started me down this path. I've listened to them since (not the S3's, though) and what I've noticed is that the B&Ws are a little bloated in the bass, and kind of relaxed overall. That's not to say they're not a fine speaker, but I don't regret my decision to go with Axiom for even a second.
