The new amp by Mr. D'Agostino (formerly the founder and chief designer for Krell) might be a contender. I've only heard it at a show (powering Wilson Sasha speakers), but, I was impressed with the fact that it did not have the kind of brittle, edgy, sound I associate with much high powered solid state amps.
That it is compact, reasonably decent looking, doesn't cook a room, are pluses too.
