How about the Kara Chafee designed deHavilland amps?

FWIW, I definitely liked what I heard from the GM70. I am trying to think of another design I have heard good things about, but am drawing a blank at the moment.
BTW, how does an amp get any more refined than an Atma-Sphere? With God as my witness, and I don't say that lightly, the first time I heard the M-60 I had the same feeling I had when I met my wife.
