Loss of interest in SACD? There are now over 6,000 releases (check out SACD (dot) NET, a "neutral" reference source).
Yes, the "mass market" American consumer never developed any "interest" and the pop/rock market have "lost interest", but the format is alive and well.
A search found Theo's remark above - sad to say, doesn't seem to be any response from the "powers that be" about WYWH, which has perhaps my favorite saxophone solo - with the right speakers, the imaging is wonderful. Not to mention the high quality of the album as a whole.
"Powers that be" - get WYWH released on surround sound! I'd vote for SACD, but if there's an audio-only Bluray format ready for market (that is, beyond just a theoretical "capability"), then be pioneers in BluRay...
But get WYWH release in surround sound!
