Those of us who have remained skeptical after reading glowing reports of
tremendously improved sound quality due to the wider bandwidth of SACD and
DVD-A can find quite a bit of vindication in this report:

Basically it shows that SACDs come in two flavors - those with absolutely no
music above 22 KHz (your typical remastered recording) or those with
negligible music above 22 KHz (your typical new recording).

The author of this report is a well-known expert who has been studying the
requirements for more lifelike reproduction of music for decades, and has a
number of successful products to his credit.

I see just another indication of how unreliable the high end establishment
is as a source of information about what actually sounds better.
