Has anyone ever switched to Harbeth

Well, if its just that you are bored at least you will be trying something significantly different sounding from what I have heard.

Here's a link to a system thread here where the owner switched from a nice pair of Dyn Confidence to Harbeth that drew a lot of interest. Check that one out.

I have not heard Dynaudios, but I understand they have excellent dynamic capability, some models better than others perhaps. I loved the Harbeth SHL5's but needed a speaker that could handle heavy music without breaking up. If that's an issue, it might not be the right speaker for you. If I only listened to instrumental, jazz, and some orchestral music at lower volumes I would have gladly kept the Harbeths.

I'm a long time Dynaudio fan / owner that recently switched to Harbeth on a whim. Made the move from Dyn. C4's to Harbeth M-40.1's. Both are great speakers with the Dyn C4's having the advantage in aesthetics, transparency, resolution and "wow" factor. The Harbeth's have a very simple, plain Jane appearance and excel over the C4's in their ability to sound good at low to moderate volume levels, and they just sound more "right" to me. I compare the Dyn C4's to an exciting high performance sports car, whereas the Harbeth M-40.1's are more of a comfortable luxury car. Of the two, I'd say Dyn's are a more neutral audiophile speaker... and the Harbeth's are more colored having a more sweet, organic house sound. Both the S3.4's and Super HL-5's are good choices, albeit different sounding.

taters will have to spend 10k plus to wind up in the same neighborhood.

As an owner of Confidence C1's and a past owner of a few Harbeth models, I think Pdreher's description of the sound of the two brands is spot on.
