Bill, in the 1980's Ying Tan was a dealer of rare LP's in his little apartment a block off the famous corner of Hollywood & Vine, location of the Capitol Records circular building. I went over to his place a couple of times and bought from him. A nice guy who didn't over-charge "too" much. I seem to recall he had a Keith Monks RCM, a very expensive machine at the time. His apartment was stuffed to the gills with LP's!
Next thing I knew, he was an audiophile reissue label owner, along with Michael Hobson of Classic Records. I never heard what happened, but Hobson bought out Ying after only a few years. I haven't seen him since.
