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?

The best speakers I ever heard used to be Magnapans, their top of the line while in Salt Lake City. They remained my remembered most impressive system until I heard the Genesis 1.1 in LA. Driven by spectral amps feeding of an Oracle CD (I didn't remember the preamp), these things were truly amazing.

Coming in at third now is my current system with the Infinity IRS V. I should be able to up that to #2 with some better front end equipment than my Adcom amps and parasound pre-pro, but this high up, the room starts to really make itself a large factor.
Klipschorns! with a close second to Magnapan MG-20s. Dynamics, clarity, wide soundstage! Oh boy!
ATC active 100's. Can any passive speaker equal active speaker technology? ATC supposedly hads the most accurate mid driver made as well. I haven't heard nautilus 800's but I think ATC beats Thiel 6's.
