The best speaker you ever heard?

Magneplaner 20.1...A very difficult and subjective question...my experience was when I was in an adjacent room when I thought there was a piano player at the keyboard....what I was hearing was a pair of Magneplaner 20.1s biamped with a pair of ARC Ref 300 and a VT100MK III. The source was an LP on a Clearaudio Turntable ?? ..can't tell you the cartridge or arm or cables....but when I thought there was an actual piano playing instead of recorded music, that was the critical mass info I needed.
The LP was a Mercury Living Presence solo pianist recording of Pictures at an Exhibition

MBL, with MBL's best electronics driving them. It was a hypnotic moment in audio, defying all preconceptions of 'recorded music'.
The old addage, that, "Nothing is live music, but live music" is correct--but that ineffable illusion of 3 dimensional, holographic recreation that I experienced, was not to be believed or understood--at least not by me.
My congratulations and ultimate respect to MBL. At this moment in time they are the "Masters of the Audio Universe."

Good listening,

If ever there was question with no potential for agreement, this thread's question is it. I was about to add a speaker but realize it is useless.

Wilson watt Puppy 7. I like to listen louder than most people and many speakers start to show weaknesses as you wind them up. The dynamic capability of this speaker is great. Even at "normal" listening levels, it's hardly trying and the result is an effortless super clear sound.

I'd have to say Barack Obama..
