Hi,
I looked into this myself at the time and I understand my Korg DS-DAC-100 uses the same driver as your DS_DAC-10R unit so this should work the same.
I have this setup to playback Roon via HQPlayer for best quality. This achieves bullproof up-sampling and playback of DSD128 using all Roon sources and formats. I output to active monitors via the Korg balanced outputs without a preamp, using a passive balanced volume control between the Korg and the active monitors. This additional volume control was needed as the volume control on the Korg unit only controls the headphone jack.
And it does sound good as well 
So it is possible, hope this helps, Neil
