High Efficiency Speakers Your top 3 or more

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.

Since we are on the topic, I would like to ask, if anyone can comment on Tannoy Westminster Royal SE performance, compared to, let's say Avantgarde Duo, or Classic Audio Reproductions T1.3, in terms of dynamics and their ability to play rock and complex classical music.(Avantgardes and CAR are the most dynamic speakers, I've ever listened to).
I've read some comments here, that Tannoys couldn't do it well.

Tvad, I keep forgetting to ask you, what amps and preamp have you been using with your Audio Note speakers now?
