How's the Audio Research Ref Phono 2 Working Out?

I'm curious about this myself. I have now (and in the past) had equipment from Audio Research and Pass Labs. I have the Ref 3 preamp and Ref 8 CD player and I have been using the Xono phonostage for 6 years. Has anyone compared Xono to the Ref 2?

This is the fifth ARC phono stage I've owned, and by far the best. Detail, depth, width are all superior to previous models. And totally noiseless in itself.
