As I've said many times, the difference to my ears is very big indeed. And that is listening in stereo. I am sure in mono blind testing, I'd hear a bigger difference. In my room, the actives disappear; the M100s do not. The M100s also don't have the clarity of the actives (not as neutral), as precise imaging or width. Depth could be debatable. Bass is far more linear on the actives too. I need XT32 on the 100 but not the actives. The actives also go louder with less power and distortion although that isn't a factor in my room.
