The best speaker you ever heard?

"'The people making comments including myself, no matter how experienced have limited comparisons. There would be other loudspeaker design we would consider if we heard them irregardless of taste.'
--Armyscout41

"Excellent point, Armyscout41. I would bet that few of us have heard more than a handful of speakers in which all other conditions are constant. And I'm certain that many among us would change our response 2 or 3 times in the 5 years that this thread has been running."

I agree with Evita and Armyscout41. It's essentially impossible to do TRUE A/B comparisons with a significant number of speakers because of their size, etc. This point became immediately obvious to me at the 2007 RMAF. I do NOT claim to have heard every speaker (well, DUH!), although I have heard quite a few. With that in mind, I will state that I think the best I've ever heard are the

Denalis by Intuitive Design.

Aerial 8Bs on a Theta system.

I don't think you can ever hear a speaker. You can only hear a system, which includes the room it is in, as well as the listener's tastes and biases.
