The most dynamic speaker you've heard...

I simply adore dynamic speakers - the pretty sound of a soprano piercing my heart is living at it's best for me.

Could you share your experience with the most dynamic speakers you've ever heard?

I do realize it is an old thread, but I figured it won't hurt to write my input.  

The most dynamic speakers I have heard are the ones I am using at this time, PIERRE ETIENNE LEON M II. You have to hear these.

The B & W 801 S3, I don't want to rule them out, but I feel they were a very large for my mid size room.  

The other thing is that you have to have a good amp as well, or you would not be able to hear the full dynamics of your speakers.
