Thanks for the response folkfreak-- I did know that Redbook was the original CD standard format, at 16/44.1 (Sony-Phillips 1980), but I thought that some more recent recordings were being pressed to disc in higher density/bitrate formats, such as 48/96. Am I wrong about that? Unfortunately, most folks have gotten used to calling all these discs "CD's", which makes things even more confusing.
Your second to last paragraph says that there is "no commercially available disc format" for higher rate DSD, but that seems to contradict the markings on several albums I bought recently (2002 remasters of Rolling Stones such as Let It Bleed and Beggars Banquet), that say they are "DSD Remastered" -- are you saying those are remastered in DSD, and then re-converted to PCM? I can't understand what the point of that would be.
