Wilson Sasha W/P amplifier pairing


I acquired a pair of Wilson Sasha W/P speakers this year. They’re Series 1 Sasha’s. Now trying to find great mono blocks to power them. My other system has Harbeth Speakers and a Pass Labs amp, I love the combo and can listen for hours without fatigue. I’d really prefer something warm and non fatiguing for the Sasha’s. 
 

Amps I’ve tried so far:

Pass Labs X350 - too bright and forward, etched vocals, not a lot of sparkle but plenty of authority

Pass Labs INT-30A - much better all around than the X350 but still too bright and forward. Not nearly enough power for Sasha. End result is too cold and thin

Bob Latino ST-120 - this is a $1200 kit tube amp I built. 60WPC. This amp was surprisingly kind of magical with Sasha.  Never fatiguing and full bodied. Unfortunately it went up in smoke because I can’t solder.

 

Mono blocks I’m considering:

Audio Research Ref 160M

Lamm 1.2 Reference

Pass Labs XA100.8

 

Preamp is a PrimaLuna EVO 400. Rega RP3 with Exact cart. Denafrips Ares II DAC streaming Roon via MicroRendu. Any advice welcome.

Luxman is certainly a contender. Anyone ever mono blocked a pair of M900U’s?

D’Agostino and Gryphon seem out of reach but I’ll consider. 

op look at zesto eros  amazing build quality musically neutral great bass low noise very flexibile and extremely reliable.

 

sounded as good as a 40k cj amp we had previously.

@audiotroy Every Zesto room I heard at Axpona was amazing, it not only sounded great, it felt right on an emotional level. Along with the ARC Ref / Vandersteen bookshelf room, I really got tube fever. 

Try a pair of Pass 60.8 - unless your room is large and/or you listen at high volumes.

You have the option then to put the money saved over the 100.8s into a better preamp.

 

I have the Sasha 1's.  It is easier to say what I have tried which does NOT drive them.  PS Audio, Classe, Hafler do NOT drive the bass driver which can dip down to below 2 ohms.  I purchased a used set of Rowland monoblocks and WOW!.  They came alive.  I have heard the new Sasha DAW's on D'Augustino's and was not wowed.  I went to LMC in Scottsdale who has both the D'Augs and Burmester - the Burmester's were very very good.  If I did not have Rowland I would do that one.  Have fun with your Sasha's - there really is no other speaker like them that I have heard.
