....."a tape designed specifically for cutting vinyl masters would have been EQ'ed to phono RIAA standards."

What that says to me is that you're implying that the reverse RIAA eq is applied to a tape. Maybe it was done this way at the outset of tape-mastered LPs? Otherwise, the reverse RIAA is done in the cutting preamp electronics, as the lacquer is being cut. The tape that's running in the machine at this point would be perfectly fine for mastering to SACD, and a comparison would be 'valid'. I saw your post as 'disagreeing' [perhaps the wrong word] with the original poster's hypothesis, which was that a tape that had been "pre-EQ'd" for vinyl mastering could still serve as the mastering source tape for both vinyl LP and SACD in a comparison. Any "pre-EQ" [and probably compression] that was meant "specifically for vinyl" would not include inverse-RIAA eq.
