I think Harty601 has hit the nail on the head, what is your NAS & does it support DSD or are you storing the file on a PC or Mac. I'm not sure about JRiver & it does not appear straightforward, it looks like it runs a DSD file but does so by converting to PCM. Maybe worth trying another media server. Also is the 272 connected over ethernet or wireless as wireless can struggle with high density files depending on its operating environment.
If it turns out your NAS & its media player do not support DSD, the DSD file can be converted to WAV or FLAC with dBpoweramp so at least you can hear it. But before that, it might be worth an e-mail to Sound Liason explaining your problem & will they allow you to have a 2nd download in WAV or FLAC - but remember to keep a DSD copy for the day you can play DSD
On the subject of Carmen Comes Inc. - Thousand Shades of Blue, that is a superb album, I was listening to it last evening.
