Best amp for Wilson sasha DAW

The best combination I know for the WA is VTL power amps and ARC pre-amps.I have the WATT/Puppy 5 with VTL MB450, ARC LS25 II, and ARC DAC9.
It’s really good.WA are known for using VTL Siegfried power amps as one of their reference amps.
As for ARC power amps you can’t go wrong with them, but the VTL’s may have the edge in grip, bass and power.

I heard some DAWs powered by a stack of Naim gear. Sounded OK. Solid but unremarkable. Then ARC monos+preamp combo that was better and finally a Burmeister amp (was like $100k lol) and that sounded better still.

None of it wow'd me. Not sure why.

There is a video somewhere on YouTube where a Chronosonic owner tells that Wilson Audio is using VTL amps to develop their speakers. It should be a good fit.

You mention 20k is your budget… is that total budget or just components? You can easily spend that on speaker cables, power, interconnects etc. makes a huge difference for recommendations. Are you dead set on separates or is an integrated possibly part of the discussion? What, if any, components do you currently have? Are you looking at analog, or digital, or both. Need more info. And congrats on your new speakers!

At Excel Audio in Newport Beach, I recently heard a pair of Sasha DAW driven by the mid-level BAT preamp retailing for 15K, and the BAT Rex 3 amp, retailing for 20K. Digital front end was a DCS Bartok with the master clock. I felt the music in my spine. My jaw is still on the floor and my spine is still tingling three days later. It’s the only Wilson set up at an attainable price point I’ve ever heard that knocked me out like this. Sensational.
