I know this goes against what Alan just wrote but having just A/B'd a set of original M22s to M22v2's, I did notice a slight increase in top end performance in the originals. The v2's were slightly less open, airy, forward, the keyword is slightly. If I hadn't done an A/B I never would have known there was any difference. I do not know if this is just a unique situation pertaining to just my M22s or if it would be something that is across all of the M22s. I can say that the M22v2 XO has changed it's lay out compared to the original, so maybe this has affected the sound a little. I also remember someone posting about a replacement driver having a different look to it than his original, possibly this has made a slight difference in performance, although he did state he could not hear any difference once installed.
