Sorry here, a typo: DLNA = Digital Living Network Alliance
It is a device used so that your music files can bypass your computer while still using the computer to control the flow of music, as with JRiver. Bypassing the computer is good since it usually has a lot of noise within.
Over a number of years I had ripped all my digital music (CDs and SACDs) to a NAS (a hard disk) for playing through a desktop directly to a DAC. I was completely bypassing an Oppo 105, still used for video. I was committed to the JRiver filing structure for all disks and some additional purchased files.
The JRiver program actually recognized the Oppo as a DLNA bridge. The music went from the hard disk to the Oppo bypassing the computer, though controlled by it, and straight out to the DAC. IIRC using the Oppo the .dsf files were converted to DoP files and sounded vey good.
Eventually I replaced the Oppo as the DNLA unit with a SOtM device and the .dsf files went straight through by USB with SQ for all files much enhanced.
