going on about the OPTIONAL watermarking.
Temporal distortions are nonsense cooked up by technically impaired audiophiles.
DSD noise is the real crap you can't remove from a recording without altering the original content.In the brittish Hifi Records Review magazine they did the experiment by overlaying a 24/96 recording with dsd noise. A difference between the original recording and the dumbed down dsd version was detectable.
A real dsd recording suffers more because noise shaping affects the sound through in band filtering. Noise is shifted up in the spectrum and some of the musical content is shifted in the process as well.Frank
