The best speaker you ever heard?

Since this thread is still going strong, will chime in from my recent discovery.

Usher BE10/20, incredible reproduction of minute details and leading edge dynamic that are hidden in most speakers. Superb integration of tweeter and midrange due to similar material used (Beryllium) and close proximity physically. Able to play loud despite only having one tweeter and one midrange per speaker, this has the advantage of reproducing more focus sound unlike those multi tweeter/midrange speakers. Excellent bass, beautiful craftsmanship, and sexy real wood cabinet.

I also like Analysis Omega (superb transparency and coherence like Apogee), Elac top of the line model (excellent top to bottom, though a little soft), and MBL101E but not with MBL amps which produce too much bass output.

Tbg, Usher is the only speaker I heard with Be tweeter + midrange, never heard the Pioneer nor TAD and I am sure they are exceptional as well. I like Usher for its look, sound, and price. TAD is weird looking while Pioneer doesn't nearly go as deep as Usher. Usher BE-20 uses 2 Eton woofers per side, they produce serious bass that is tuneful and musical.
