The best speaker you ever heard?

I never heard the two Rockport speakers above the Altairs (my absolute favorite), but if they are better - they must be wonderful.

1. Rockport Technologies Altair (great all round)

2a. Avantegarde Duo Primo (breathless - emotional)

2b. Hansen Prince v2 (again - just how much better the Hansen's above this one)

5a. Tie: Leonard Norwitz's Audio Note System (in his place - just music)
5b. Tie: Wilson W/P 8's (IMHO in my environment and system for now - music with more dynamics when required)

Cambridge SoundWorks Model Six - I love them almost as much as my old Ohm E's which finally bit the dust.

"Cambridge SoundWorks Model Six - I love them "

...and at $99 a pair a rightout bargain, and that's really the best you've ever heard Jkl2000? If you get serious about this high-end hobby you're in for the ride of your life!

perhaps the question can be rephrased, for example:

"what speaker would you be willing to live with for a long time ?"

my answer would be : stacked quad esls and apogee duetta signature

Mrtennis, Quad ESLs are good, but having owned them thirty years ago, I would not consider them the best I have heard. There is so much interaction between front end, amps, cables, and speakers that I think it is hard to say what the best speaker might be.
