Isn't it interesting that we "subjectivists" here are always whipsawed by
the "objectivists" for thinking that extended frequency response is a
benefit "because it can't be heard". Then, in defense of DVD-A, the
increased noise in the ultrasonic range is bandied about as making DSD/SACD
"inferior".


Actually it's interesting that subjectivists said that they need the
ultrasonic bandwidth to fully perceive music, and yet they like SACD's
despite the much higher (by orders of magnitude) ultrasonic noise
inherent in the SACD format.

What some of the more technically inclined are saying is that even
though the ultrasonic noise from SACD's may not be audible on its own,
there is a possibility that such noise may cause problems in amplifiers
and speakers, which result in intermodulation and other effects that are
audible.
