It plays DSD. My NuPrime IDA-8 on the desktop system (I use JRiver on it) will play up to quad DSD (I have a secondary system with a Hegel integrated/DAC that only does up to 192 and has limited USB functionality so I have a USB to coax converter and I use JRiver output settings to take DSD files to 176.4 PCM). There are audio settings. First step is to download it and go thru the 'Tools' (near the top) and then 'options' and there are a bunch of Audio settings, including drivers, sampling rates, DSD, playing back the decoded file from memory, etc.
