List : Components with high dynamics

I have to admit that I like high dynamics among other things when it comes to my components. For all of you who like me like to try new components every so often and have come across a highly touted component that is rather sluggish and dissapointing, could you name some of the highly dynamic component out there you know of.

I'll start with the following:

Symphonic Line
Krell
BAT
Eastern Electric Minimax
PrimaLuna Dialogue II
