V2 and earlier version are basically the same, minor differences with the binding posts, crossover layout was changed. I have A/B'd v2 with my v1 and found the v2s to be slightly more laid back/smoother but otherwise both versions very very good.
There is still GST with the FO speakers.
Oh yes, a big improvement in SQ from HTiB speakers, although some may find the lack of boom from the M22s to be poorer SQ, but once you realize the greater details you are hearing with the M22s, you will be more than satisfied.
White vinyl?, Do you mean the light maple finish? I own it and it looks similar to bleached oak.
Maybe try checking out the hearing things forum for someone nearby to give you an audition or call Axiom to see if they could set up an audition with an owner for you.
And welcome to the boards.
