RE: DSD [A Reprise]...

"Sony invented DSD"

Beg to differ. Sony and Philips invented SACD, the optical disk and associated encoding and DRM technology. They invented some editing techniques. However, DSD is just one bit PCM at a high sample rate and the methods of generating it (sigma delta modulators) were previously known. What they did do was standardize a bit rate, recording levels, and placed requirements on in band and out of band noise for acceptable implementations.
