I own a Clayton S40 and love it. I use it with Audio Research sp9 Mark III. I have talked with Wilson Shen directly and he says that he still has hopes to release a preamp in the future but it is currently not available.

Clayton P2000 Pre-Amp
I can find very little information on the 'net about this pre-amp. Does anyone have any experience with it?
