Klyne pre-amps, any experience out there?

I have been a real fan of Klyne preamps since the mid-1980's, when Stan used to infrequently attend meetings of the Pacific NW Audio Society. He would sometimes bring a prototype of the next preamp that he was designing, and the quality of the internal parts and the assembly was always very impressive. All of the Klyne preamps that I've heard over the past 15+ years have been excellent, and in the right system they compete with the very best high-end SS preamps being manufactured.
