Since Zoo brought up Steve Hoffman, I asked him to comment on this discussion. Here's his reply:

Hi Donald, Don't worry, you're not bothering me... I took a look over there... Some points... No LP's can even cut a 15k tone without a great deal of trouble...Most cutting heads start to lose it around 12k, and it's all downhill from there, especially as the stylus gets to the inner part of the lacquer. It has nothing to do with the manufacturing process, it's just the way a cutter head works. We never notice because of the lifelike analog sound. In fact, a record cutting is a true "analog" in the literal sense of the word. Still, nothing up there but tics and pops, I'm sorry to say... Of course, an LP cut before the German systems came in to being in the early 1970's, usually have NOTHING above 12k.... You can quote me, but get ready for the flames! Best regards, Steve
