The Oppo 105 plays them superbly, and if you install the new firmware, it will play multi-channel DSD files, the highest resolution available (2.8224Mbits/sec!). It plays 2-track DSD files without the update. I only have a handful of files on a USB drive, so I can't speak to the way it deals with play lists. I do not, however, have any problem finding the files I want. I do understand that the 105 leaves something to be desired when it's connected to a network and it plays files from one's computer. You need CUE file to make sense out of the playlists in that case.
