I'm hoping Mark Donahue will chime in here. If they were comparing 96/24 PCM to DSD, when the audio
was digitized to 96/24 PCM in the first place, of course they'd hear no differences. I remember this
issue coming up with the Mercury Living Presence SACDs, which were done in Germany with no direct
involvement from any original Mercury team members. The only time DSD came into the picture was
after all the transferring, whatever DSP was deployed, normalizing, etc. The final PCM files were
converted to DSD for SACD disc authoring. A beef in the audiophile press at the time was that "no
advantages of SACD were realized," that they just as soon have put out 96/24 DVD-audio discs (which
actually would have been a better idea since most DVD players until the recent generations of
ultra-cheapos could play DVD-A discs whereas fewer players could play SACD). Anyway, supposedly the
advantages of DSD are only heard when the product is DSD from input to output, which is what Mark
Donahue did with the RCA Living Stereo SACDs.
As far as I know, during most or all of the time that Universal was playing in the SACD world, they
were doing their transferring and production in PCM, then going to DSD for the final SACD authoring.
It may all have been based on that listening test mentioned in this thread, but I'd argue that the
test parameters seem flawed.
