I am converting all dsf and SACD iso files to 176.4 PCM on the parent machine as there are no drivers for SACD over HDMI from the PC. I can play the dsf files on my Marantz if I use DLNA over the network. It is not a USB capable DAC. When I sync any aif, flac, or wav file, the file comes across to the other PC in unaltered format, displaying the proper sample rate and file type. For any dsf or SACD iso, the ZoneSync converts the file to 176.4 wav with no sound. It shows the cover art and song info but "plays" the file as white noise.
