What amp is best with Wilson Sasha DAW speakers

ARC > VTL on Wilson in my experience. Only the 75SE and more recent ARC however. The older stuff sounds like SS.

Hi 4425:
1-i prefer ultra linear mode
2-build quality is great and they are very cool looking amps although in the first few runs, the see through double pane plastic on the face of the amps in which the meters are sited are not as clear as I would like. I believe ARC may have solved the problem in later runs. I love the meters and they do not distract from the presentation. 
3-These are simply great all around amps with the typical ARC broad macro presentation but with very revealing micro dynamics and powerful deep bass. I love them. My personal opinion is that ARC and VTL are the best tube amps for Wilson. And I prefer tubes over solid state although I am also a fan of D’agostino solid state with Wilsons.

Gpgr4blu:  are you using a full ARC system?  Which preamp are you running with the ref 160 with and cables too if you don’t mind. 

Hi carey1110:
I have a Ref 40 pre and a Ref Phono 2 phono stage. My cables are mainly Shunyata Anaconda Zitron although I use MIT for my Spectral cdp and Audioquest WEL signature reference for phono cable.

Hi carey1110:
Have had my Sasha DAW's for about 5 weeks now.  They are paired with Convergent Audio Technology Renaissance preamp and JL5 amplifier.  I would say it has the organic qualities to it.  Enjoying the combo immensely. I just keep putting on more music. Still getting better as speakers are still breaking in.  Have fun with your search.
