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?

I use Accuphase e-450 as integrated amplifier of my Sashas. I´ve already ordered e-560 to replace my e-450, because I think I have never heard a better combination with my set. A friend of mine brought the e-560 to my house and the result was outstanding. I was happy with the e-450, but with the e-560 the sound is much better.
