Best Integrated amp for Wilson Audio Sasha


Thinking of the Gryphon Diablo, Acuphase E560, Passlab Nt-150 or Dartzeel 8550 for the Sasha. Any recommendation from those using this speaker?

"So who needs this?"

It was the author of the thread who asked about darTZeel - it was not an unsolicited recommendation.

PS - Lange is a German, not Swiss, watchmaker.
To correct my earlier post, the ARC amp I heard powering the Sashas was the ARC Reference 110 power amp, driven by a line stage from the same Anniversary Reference series.
"Dob- I don't know what you are saying, but the speaker is not particularly easy to drive"

Hello Keith - it is poorly written joke. Efficiency is related to air pressure of sound not its quality...

Sorry, of course, you are right - sound quality at certain frequencies will be much worse then at other due to difficult loads.
