I noticed on HDTracks that DSD is available for some albums now, what is surprising is its cheaper, often £14, than other formats such as FLAC, also it is often the only format that is available to UK residents. So if you are looking for a certain hi res album it maybe worth a look at DSD. I find the site a nightmre to navigate. The search function is pretty useless, the best way to find them put in DSD and it should come up with them all or if you are in an album then you have to go to sample rate and see if DSD is there.
