This is probably opening a can of worms you don't want to open and I understand if you don't want to answer this directly, but I will ask anyway.
Now that you have mastered some of Keith's tapes to both the TP format and to vinyl, I am curious as to how you would compare the strengths and weaknesses of each format. Also, what about the intermediate phase like the running master dupe for the tape vs. a fresh cut lacquer from his master (as opposed to a vinyl pressing). Is his master tape from his analog machine patched into the lathe or is there another intermediate step in that process?
Reason I ask is that I have had a friend with an excellent lathe cut something right off of a safety copy of a tape (15 ips/ 2track) without alteration (real time @45), and that lacquer blows away most pressings I have heard. It pretty much sounds like the tape.
(BTW, I think Doc heard a 16/44.1 CD reduction of one cut from that lacquer that I brought to the show in the bay area recently in the room where he was playing TP tapes with Luke Manley's amps.)
