Hi afonda,
I posted the original comparison of the M22ti vs. the Studio 20 because I've had the 20s for years, as well as the M22s.
I'm not aware of the V2/V3 designations, nor have I heard those, but the original is extremely close to the M22ti--"virtually indistinguishable" in a blind comparison, or, as I sometimes term it, "similarly good." I apply the latter label when two different speakers are so close that you may prefer one over the other on one musical selection, then switch your preference to the other speaker with a different piece of music.
Actually, I feel the Axiom M22ti is slightly superior to the Paradigm Reference Studio 20 because it doesn't have the slight hump in the 100 - 200 Hz region that gives male vocals a bit of a "fat" or "chesty" coloration on the 20s. I also find the M22ti's have a slightly more detailed 3-dimensional soundstage than the 20s.
Regards,
