Moving to a dynamic speaker from a Electrostatic

I've had good luck with both ESL's and dynamic driver's. Ultimately, your personal taste is going to be the deciding factor, but one speaker I recommend you consider is Vandersteen. I find them to be as coherent as any speaker I've ever heard regardless of design. Not only that, you should also look forward to what a dynamic speaker can do that ESL's usually can't. It's very likely you will find that you are upgrading the sound of your system in certain areas.

That said, the most important thing to keep in mind, I feel, is to consider what the entire system will be, and not just speaker A vs Speaker B. All the other components are every bit as important as the speakers. (I'm sure you already know this but I still think its worth mentioning.)

Moved from Maggie, Auditioned Quad ES. That was the sound I wanted but with better dynamics/slam, and at a lower price point. Ended up with OHM Walsh.

You didn't mention price point. But I just moved from the Dynaudio C1 sig to the Raidho D1. The Raidho to me sounds more like an electrostatic speaker but with better dynamics. I never heard the 'C' series but read they are pretty close for a lot less money (especially since the diamond series was released).
Good Luck ;)

I had ESLs for nearly 8 years. Started with ML Odyssey, but found the sweet spot way too narrow. Moved to a pair of Quad 2905s with a pair of REL subs and was convinced I could never go back to a conventional box speaker with cones. The Rockport Aviors I have had for over a year are superior to the Quads in every conceivable parameter. Of course a lot depends on the room and the associated gear.

Xti16 I think my price point will be near 15k and less.My system right now has audiovalve challenger monoblocks with kt88's and I also have a pair of roland model 6 monoblocks so I can go either way but maybe leaning to going back to solid state.
I always find myself recommending Merlin speakers to people so it will probally be one I will be considering as well as
Aerial,YG Acoustics,Focal,Wilson,Nola,Von Schweikert and Verity.
