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. Cheers, Richard Richard L.
