Charney Audio!
Have owned a pair of Maestros 100db (Omega RS7 driver) for over a year and I’m still amazed at what I hear. Clean open 3D presentation with deep articulate bass to boot. Beautiful to look at and wonderful to listen too. Charney also builds Lowther 103db and Voxativ 103db based Companion and Concerto that are a clear step up form the Maestro. Each of the tractrix theory designed horns play well above anything out there in respected price ranges...go listen at Charney in NJ well worth the trip!
I have Zu Definition 4s and like them a lot. I drive them with a 300b SET. I have also heard and liked the Audio Note AN-E. There is an online commentary about high efficiency speakers: http://www.high-endaudio.com/RECENT.html#Nov

I'm surprised no one has mentioned Coincident.

Also, Spatial Audio now makes a special triode-oriented variant.
