"I have some Rolling Stones DSD CDs produced by ABKCO in 2002."I think geoffkait is asking about a batch of CDs (NOT SACDs) that say "DSD" on them. I would think that they are same as CD layer of initial hybrid SACDs. Just converted from ISO files, or something like that.
This is a picture of one of them. Note the sticker.
