Wierd I was just about to post a similar DSD related query/issue but I'll chime in...
Looks like your DAC doesn't support DSD so mpd will be converting to PCM on the fly, there is no need to convert the files if your'e not concerned about disk space.
The output PCM sample rate will depend on the DSD format, DSD64 will convert to 24/96, DSD 128 will convert to 24/192, DSD 256 to 24/384. Going beyond the boundaries of your DAC, DSD 512 converts to PCM 24/768 but on your setup is may be converted and downsampled to PCM 24/384 if the CPU can handle it.
You can force a specific sample rate with the SoX resampling setting if you wish which I think will resample everything, not just DSD.
HTH
PS: Got my rates wrong of the top of my head but Tim has updated with correct numbers
