The best speaker you ever heard?

The Big Corner Klipschorns. I listened to a pair at a local salon here in Detroit that was driving them with an Ampeg reel to reel playing a very large tape with "Dark Side of the Moon" on it. I will never forget the visceral effect that listening had on me and most especially the intro heartbeat... Nothing since has had that same effect on me and I've listened to a lot of systems.

It would be wonderful to run into something new that could go beyond that time and that's why I keep listening every possible chance...

I have owned some different speakers but the ones that for me are really much better are the Dionisio speakers by Yamamura Churchill.

Having heard and owned horns, electrostatics (many), electromagnetics, ribbons and many other dynamic speakers for me the Coincident Pure Reference has a presence, tangibility and transparency that is unbeatable except perhaps by their PR Extreme.

tidal contriva diacera-se....my guess is that the more expensive 'sunrays' and t1 sunrays' would be better in the right room but in my room the contrivas'rock...

I agree about the Contriva DiaCera SEs. When I first heard them, I knew this was the exception to my conclusion that all speakers were compromises somewhere.
