Anyone Using DDC With Rockna Wavelight

If anyone is using a DDC with a Rockna Wavelight, please share your experience.

I have a Bricasti M5, and recently acquired a new DAC, a Rockna Wavelight which has an I2S input.  I am currently connected via Kimber D60 coax cable. Am curious about benefit of inserting DDC in order to leverage I2S.  

Thanks for sharing your insights.
