what is the best amp you've ever heard

Now that I own them after a week, the Joule Electra VZN100 is the best sounding amp I've heard to date. This after owning the Decware Torii MkIII which is no slouch. This by a wide margin.

The best amp I ever hear is the el cheapo one connected to a 100k set of speakers.

Just joking of course, but this question is SO system-dependant....

Shoot, have heard so many!

THe thing is one cannot hear an amp without all the rest so how to say which amp alone sounds best?

The amps I can identify in the best systems I have heard recently are VAC, MBL, ARC, ROGUE, Bel Canto, Boulder, Audio Note.

VIntage-wise, I retain a soft spot for Tandberg amps as some of the best sounding I have heard.

Hope to attend upcoming Capital Audiofest in DC and hear some more.

BAT Rex mono-blocks!!! ... and so very fortunate to be able to own them.

enjoy
