Axiom can't touch B&W, Focal/JMlab, or MB Quart.
Two other key players are Dynaudio, and Sonus Faber.

I would say that the five companies listed above are of the best you can buy. I put Axiom in with mid-fi, such as Polk Audio, Paradigm, Boston Acoustic, Mordaunt Short, and Monitor Audio. I consider Monitor Audio to be the best of that bunch.
