If you are looking for owners that have stuck with them for awhile, I upgraded from Quad ESL-63's to Gallo Ref 3's about 2 years ago after auditioning countless other speakers. I have written a lot about them on these forums, and still think as highly of them as when I first purchased them. I find the sound very Maggie / Electrostatic-like in a more convenient package.
Lately, I have been considering Zu Druids to explore the low-powered SET route, although I am still undecided. With the possible exception of the Zu (as I said, I am undecided), I have yet to hear another speaker that makes me want to change.
