Best Integrated, period.

Symphonic line Kraftwerk mk2, they make great amps.
Blue Note Demidoff Diamond, never heard it but it should be interesting.

I prefer when a integrated is a onebox solution otherwise it looses its appeal a bit, a least to me. Therefore the ASR with 3 extra boxes is out of the question.
Heres another: Consensus Audio Amp 211.
The Vac Phi Beta is definately interesting, still wonder about the others and how they compare.

The Blue Note seems to be the most expensive one so far at €19990.

It depends on the speakers being driven...

Hi Perrew, you should still tell us what kind of sound you are seeking. . . warm/neutral? Extended/cozy? tube-like? SS-like? etc. . . G.
