We have instructions on how to install Foobar2000 with ASIO plug-ins so that along with the nano/micro iDSD/ retro Stereo 50, one is able to playback DSD natively.
Please open a support ticket and we shall email the pdf to you.

Note: Foobar2000 is open-source and as such, is not as stable as other paid-for audio playback software.
