Duper masters came from all places at various times. Same problem with cassette duper masters. RCA 
might well have run a 2-track while they mastered the LP and then used it for a duper master. 
There's really no telling with mass-made reels. They could be many, many generations away from the 
master tape. One of the very late-era good-quality cassette dupe places used a better method, but 
charged big bux for their tapes. They'd have a digital tape made from the real-deal master, at a 
good mastering facility. Then they'd use the digital tape or 1:1 clones as their cassette duper 
masters, and dupe at real-time with a roomful of decent-quality cassette decks. Like I said, they 
charged a premium for their tapes but they did sound good. The only other mass-produced tapes that I 
have that sound somewhat near what a master should sound like are some early 2-track reels, which 
were made at 2X or at most 4X speed. Some companies did better than others, even in that era.
