Focal Sopra 3 vs Wilson Audio Sasha W/P (series 1)

Assuming you still have the ARC 75 amps, it looks to me like you're going to make the same mistake as you did with the Sasha's.

Just not enough current to drive either the Sasha's or Sopra 3 properly.

Because the magnitude is considerably higher in the treble, the speaker will sound brighter when driven by tubed amplifiers, with their typically high output impedances. 

Your money, your choice. Good luck with the new system.

Thanks for pointing that out. I appreciate it! I don’t find the Sashas too bright in my room. It’s pretty damped w pile
carper and treatments.
I wish the comment in the review were more specific. I think putting all tube amps under the same comment might be incomplete. But, I’m no engineer, so maybe it does apply to flea watts and higher current lIke ARC.
Thanks

If you like the sound of ARC, why not look into a bigger ARC amp first.
If that doesn't appeal, then I would consider looking for a speaker with an impedance that doesn't drop below 4 ohms.

I had the ARC Ref 150 with KT150s with the Sasha 1s and felt that it was a significantly better amp for that application than the Ref 75 which did not properly push the Sashas (even though the combo sounded very good).  ARC and Wilsons are very synergistic. I would move up in  ARC amperage.  

Assuming you still have the ARC 75 amps, it looks to me like you’re going to make the same mistake as you did with the Sasha’s.

👍

Wilsons luv current, big tubes will do, but still can't equal a good SS like a Gryphon or D'agostiono ect ect ect for getting the very best out of the Wilsons.
