I've gotten into this discussion with Larry
Miller on the Ampex mailing list, and I think
there was a compromise. I have Stanton MM
cartridges (and an Ortofon MM somewhere).
So how did the RCA CD4 quad system work? (I know,
not very well which was one of the reasons it went kerphlop)
I also think that some/many of the people making
this claim are doing flat transfers and then
digitally applying the proper (RIAA-or other) EQ.
I do see energy above 20kHz on some early 1970s
tapes of carousel-type band organs when their
little shrill bells go off. Eric has done the
work on discs, not me. I'll let you and Eric discuss this in more detail.
