The best speaker you ever heard?

Evita, I agree. Its all subjective. My response would certainly have changed a few times =)

In the 70's Snell typeA;80's Infinity IRS & Linn DMS;90's Watt Puppies fed by Wadia in Chicago Show; Now ???

Wilson Audio Specialties Watt Puppy's version 6, these speakers were paired with Audio Research Tube amplification and I think the transport was a krell cd player, but what I heard from a familiar recording blew me away!!!!!!!!!!!!! And I have heard a LOT!! To name a few, Dunlavy, Martin Logan,Paradigm, Meadowlark, Sonus Faber, B&W, Kef,Klipsch,jbl,Energy,M&K,Krix,Jamo,Infinity, Sorry If I mentioned some of you guy's equipment but everyone "hears" differently!!!! I'm a young audiophile 33 to be exact, but I think I've heard my fair share of speakers to give a subjective comment on what I think is one of the best if not the Very best.

Oh My God Man: WITH 5 ADS L 1590 II.
AND KRELL HTS, N. PASS AMPS, TRANSPARENT BALANCED INTERCONNECT.
IN HT SET UP NO SUB. Oh My God Man I can't express in words how awesome these ADS speakers are.
Absolutely amazing.
It's like taking a blindfold off of my eyes and can see for the first time.
ADS FOREVER

Well, it USED to be Avantgarde Duos...now, it's the Duo Omega. Builds upon all the strengths of this amazing speaker, and adds coherence, better air & extension up top and more effortless power delivery in the upper bass & lower mids. I am a happy camper.
