Regarding the CD vs. Sacd/DVD-A format wars...

When I asked Tom Nousaine about the sound quality differences between the two, he laughed. Then, a close friend of his said that he measured the frequency response of several clips from a CD...then of the same SACD(corrected for loudness variation). HE then smiled when he said that the base was "tipped up" on the SACD version. "Guess what THAT means?" he said. "It means that the producers are tweaking the Sacd stuff so that consumers will be able to tell a difference between the two formats.
Nuff said.
