USB vs Coax SPDIF, NUC, HiFiBerry Digi+ Pro, Mytek Brooklyn

My Roon server lives on a Windows 10 NUC10, within shouting distance of my Brooklyn DAC. I’ve been feeding it via coax from a Pi3 with a HiFiBerry Digi+ Pro. I have some DSD files that I wanted to hear natively so I connected the NUC to the Brooklyn with a USB cable. I haven’t had a chance to do any extended critical listening and don’t have anyone around to ABX for me, but was wondering if anyone else has played with a similar setup with any thoughts.
