I just started to mess around with DSD and downloaded a couple digitized albums from RuTracker. Kill 'Em All and …Nothing Like The Sun. I have heard may versions of both but they have never sounded better. I was really surprised, it was very noticeable.
From what I’ve heard from some of the few who attempted it, all the related software for multitrack DSD is pretty unusable, so there are very few albums that have been DSD all the way from start to finish. Typically it is/was only used in the mastering stage for the DSD release - basically just PCM or analog mixes recaptured to DSD (after whatever analog processing is being used) for that format release.
