I was in communication with Matt today with regard to a possible J-River problem with Windows, it turns out there may not be a problem afterall.
The source of the problem seems to be using ASIO for DSD playback... ASIO is not recommended for DSD playback, it works in some cases but not in all.
WASAPI or Kernel Streaming is recommended for DSD playback... if you are running Windows it is best to use WASAPI.
Chord are trying to find out more and whether there is a workaround for ASIO but unfortunately nothing positive yet...sonically speaking, you shouldn't hear any difference between ASIO or WASAPI.
In other news... looking into getting dB-Poweramp in the near future, I noticed that there is a streamer plug-in that can do DSD (Aset UPnP)... if you scroll down the home-page to 'Spoon's Blog' via the link below, details of the latest release mentions a DSD update, hth.
