Tube,
I am a person who does not believe the mass hysteria surrounding the ability of an amplifier to drastically change the sound of a system (somewhat technology dependant). With that opinion in mind, selecting your speaker model will do far more to change the sound than swapping the Blue Circle components for Classe, or Parasound or whatever.
I have all the confidence in the world that the Blue Circle components will do very nicely with the Axiom speakers even though i have not heard them myself.
As has been mentioned many times before, the Axiom sound is very neutral especially for the M22s (see
NRC graphs here) such that the quality of sound will be highly dependant on the source recording. The M22s should do a better job of filling a room of that size compared to the M3s.
