The best speaker you ever heard?

Since this thread refuses to die, I guess I'll finally chime in.
The finest loudspeaker that I've yet had the opportunity to spend time with had its north american debut in my own exhibit in Las Vegas this past January, courtesy of Toffco, the US distributor for Neat Acoustics.The Neat Ultimatum(US$16K) was an extraordinary experience, with the coherency, articulation and imaging of a mini monitor and a chameleonlike quality that was equally at home with solo vocalists and small combos as it was with large scale orchestral and jackhammer rock.They displayed a sweet openess and spaciousness unlike any other conventionally enclosed speaker in my experience.They are superbly fast, nimble and dynamic.The Neats could float a serene, stable and convincing ly holographic image in the midst of a cacaphony of pyrotechnical fireworks and headbanging volumes.
I found it intriguing to hear comments after the show which ranged from "lush","laid-back" and "silky" to "relentlessly driven" and "kick-ass" all dependant on the character of the recordings used during the audition.I've never heard such a "complete", expressive and alluring do-everything big system.

I own ESL-63 and I love them but the new 989 are much more neutral and has killer bass compared to the 63.
The Avalon Eidolon is the only dynamic speaker I heared that has the magic and at the same time gives you the strenght of dynamic speakers (I have not yet heared Amati, Lumen-white and Kharma, but I plane to!!)

Easy. The Wisdom Audio Adrenaline Rush and M-75 systems. They have the speed and transparency of the best electrostatics (without beaming and the "hey I'm a hifi speaker" effect), very low and fast tight bass (to 12 Hz in my room), wonderful dynamics, best imaging I've heard from any speaker. They just disappear and play the music.

I've never heard a large system integrate everything in a natural way. They always seem to foul up the bass to my ears. Live bass is much faster than most of those big drivers produce it. I have no best but consider the following very memorable in their own way:

Apogee Stage and Scintilla (the most transparent speakers I have ever listened to)
Quad ESL-63- First time I heard them I was absolutely smitten. They still have a midrange to die for and if I were to have a 2nd system it would be based around them.
SoundLab A3 I haven't heard the big boys but I can imagine, wonderfully coherent as Albert notes but not too dynamic, damn what a shame because they do everything right, I do believe the big Soundlab might be "The last speaker you'll ever own".
IRS Beta's (except for that damn bass the rest was superb)

Merlin Millinium OK so I'm prejudiced because I own them, but I LOVE their coherence and their point source nature, I can't hear the drivers crossover and this is very important. They don't have wall shaking bass but what there is is very clean, quick and natural. They fill up a room with music without bringing attention to themselves, they just disappear. They are tonally neutral and have a liveness and an immediacy that I'll never tire of. Lastly, they have a size that is easy to live with. I would qualify them as without a shadow of a doubt the best two-way speaker I ever heard, sorry Wilson.

How about the Jean Marie Reynaud Twin MK II at $845.00 ?
