Trying to decide between 2 Nagra classic, single boulder 1161, or Luxman M10-x

I recently inherited a pair of Wilson audio Sasha DAW. My current amp is a quite old Pass Labs x250.5. 

I've listened to many amps in stores, and the three in the title all sounded wonderful to me - albeit not in my home. They are also in the correct price range. I’d love any actual experience driving these speakers with any/all of these amplifiers. Thanks in advance.
