John,

No I have not yet purchased the Ma Vlast yet, but it is on my list of must-haves. I would really like to hear it on the Axioms.
In so far as the "fullness" concept is concerned, sometimes the M22s sound like I have taken the treble knob up to its max and other times it is just amazing crispness and detail. On the Ascends, The horns in one our selections this evening sounded like another musician was playing along only an octave lower, whereas the Axiom horns were more detailed but had less of a bass to them. I realize I might not be explaining this correctly because I by no means have a great deal of experience critically listening, but I do know that treble appeals to me, but not to the point of lacking any bass at all.
We were listening without the sub and the Ascends still had that extra bass in their sound.
I have been wrestling with this difference in the sound characteristics between the two manufacturers for at least 6 weeks now and need to make a decision soon.

Mark
