High Efficiency Speakers Your top 3 or more

I read some forums where the old / vintage school of high efficiency speakers - Klipsch, Tannoy, Altec, JBLs. even Audio Notes are the only way to go. On others like audiogon the newer high eff speakers - horns, Zu, Horning,Coincident, etc. are in a league of their own. I own Zu Druids but somewhat torn about which way to look next - the classics or the moderns...having not heard any of these for myself. Short of listen for myself any experience here that is beyond dogma.

Great topic and replies so far (for the most part). Fewer (actually preferably no) personal insults would be even better, but still a great topic.

The Avantgarde speakers (especially the Trio) can be quite good *when setup right* and everything gels.

But the best hi-effeciency speaker - and the best speaker, period - that I have ever heard is the Cogent horn system with their field-coil compression drivers. There is no beating that system. Of course the cost is also staggering.

Shame on you all for not mentioning this speaker.
