Best Integrated Amp You Ever Heard?

I am tired of the Pre-amp+Power-amp game. So, I am in the quest of finding a really really good integrated amp, preferably used, so I can save some money off the original price.
Right now, I have a pair of Triangle Celius (92db), but I would like the amp to be able to drive other not-so-sensitive speakers.

What is the best integrated amp you've ever listened to?


Used IMO the best one is the Gryphon Diablo 300 and it is the one i'm going to purchase.Otherwise best one i've heard at any price is by far the Audionet Humboldt.
The new Agostino progression integrated amp
is pretty awesome. The Dartzeel CTH is a truly great integrated amp as long as you go single ended with the connections. 

Another vote for the Gryphon Diablo 300. spectacular amp with lots of power - 300 W @ 8 ohms, 600 W @ 4 ohms.  Can drive any speaker with finese.
