Suggestion for best stereo amp ?

I think you'd like a Bryson 4B cubed or a top-of-the-line Pass Labs. They're powerful and nuanced and have superb dynamic balance excellent timbre and a velvety smooth transparency across scales. They like good cables, and they'll make those Wilsons divine.

Totally agree.

mzkmxcv,

Based on your remarks on amps, DACs, etc., it seems like you're convinced that only measurements define the sound quality of a component and you won't budge. That's fine but don't be so adamant  in trying to convince others. Like I said in a different thread, if measurements were the only criteria to assess sound quality, we would all have Benchmark products in our racks. Everyone else would be out of business.

Gryphon is close to the absolute best. CH Precision is possibly closer. (depending on personnel preference)

Lots of folks trying to be helpful but to get a proper answer we’d need to know a few more things. Even then we’d be taking an educated guess as to what your ears will like and even more so, what the new combo will sound like together.
Budget?
Are you sensitive to forward sounding tweets?
Are you set on class A/B?
What other amps have you heard on the Wilsons that sounded good to you?
That should help but even then it’s still no replacement for an in home audition if possible. I know it’s hard to do this without a good relationship with a local dealer, but it’s worth it’s weight in gold if you can.Scott
