How would you power Wilson Audio Sasha or Alexia II?


So I just auditioned the Wilson Audio Sasha DAW and Alexia Series 2. Both are awesome speakers, they really moved me.

Which pre and power amps should I audition to find a match made in heaven? Total budget for pre and power amp(s) is $50-60k.

From personal preference:

Luxman / D’Agostino / Ayre.


From what you should listen to if you can to form a personal opinion:

Pass / Ayre / Luxman
How about the preamp and power amp(s) you listened to when you auditioned the speakers?  If the music moved you, that is what you're looking for.
