It will depend on your player's downsampling features, but JRiver allows me to downsample DSD files to PCM to match the capability of my DAC. I have a 24/96 DAC, so my sample rate settings are:
Input Output
352,800 Hz 96,000 Hz
384,000 Hz 96,000 Hz
> 384,000 Hz 96,000 Hz
Therefore, my DAC receives 24/96 PCM files. Because your DAC has up to 24/192 capability, depending on your software player you may be able to convert the DSD files to 24/176.4 or 24/192 PCM, which would be higher resolution than standard Redbook 16/44.1.
My DAC doesn't do 88.2 KHz, otherwise I would have chosen that as the downsampled output for an exact multiple with DSD @ 352.8 KHz or DSD X 2 @ 705.6 KHz files. In my case although there is some interpolation fudging, I still perceive these files to be better sounding than my Redbook library, although to be fair I do not have the same songs also in 16/44.1 for direct comparison.
