The best speaker you ever heard?


In my opinion, the speaker is by far the most important part of the audio system. After all, it is the only part you hear. OK, the other stuff really matters a lot, but without a great speaker... No go.

I am a bit 'speaker-obsessed' I guess, and now I am wondering: What are the best speakers you have ever heard, and what made them the best?

I have owned Apogee Mini Grands for years. I have tried many speakers, all highly regarded. None, have been able to replace the Apogee. There is a certain addicting quality to their sound. Turn the lights off, put on a good female recording, and the rest is history!
The four or more tally list:

7 Sonus Fabor
6 Wisdom
5 Apogee
5 Quad
5 Avalon
5 Martin Logan
5 B&W
4 Piega
4 Dunlavy
Walk-around the musicians in your living room. Real palpable imaging with great dynamics and real bass.
Heard some top-end ATCs yesterday. $16K per pair is a little out of my price range (although that does include a power amp in each box). That said, these were the most incredible speakers I've never heard. I mean "never" heard. I felt like Count Basie, the Roches, Leo Kottke, were playing in the room for me. Astonishing! (thanks, Chris, for the audition!).
I dont really have alot of experience listening to higher end systems, but from my experience wihtout a doubt the best sounding speakers are Definitive Tech's BP300TL.
