I haven't switched from one to the other, but I auditioned both brands when I was last in the market for speakers. After listening to Dynas, both some Focus models and the Contour 3.4, for several hours at a dealer's, I thought they sounded very good. I then auditioned some Harbeths with the same recordings, and I thought they sounded beautiful. So I bought the Harbeths (M30s), and have enjoyed them very much.
My impressions of the respective sounds were, I think, similar to yours. I remember thinking the Dynas' sound to be "clean" and "precise," and I found the Harbeths to be "whole" and "rounded". I think Harbeth PR would call them "natural". After listening for that extended time to the Dynas, I was a bit concerned about listener fatigue, but the Harbeths did not produce that reaction at all.
I've been pleased that the Harbeths make my older, more poorly-recorded, discs sound enjoyable, in contrast to my previous speakers, ADS-710s, on which those discs were barely listenable. I had always considered the ADS-710s to be fairly forgiving, so I had a bit of concern about the Dynas in that respect as well. It is also possible that I preferred the Harbeths because they were less of a change from the ADS sound (which I had for a very long time) than the Dynas were.
YMMV, of course. Good luck in your search.
