Ethernet or USB for streaming to Oppo 205


Is Ethernet or USB preferred for streaming to an Oppo 205? The 205 sits near a mid 2015 Mac Mini that runs Roon core. It recently replaced an ultraRendu with Senore LPS 1.2 and Ayre QB-9 DSD.

Should be equivalent, assuming the Roon client in the 205 still works.

USB will not do multichannel.  Ethernet and HDMI will.
I've settled on Ethernet.  The setup is very simple:  Oppo 205 XLR to a Nad M22 that drives a pair of KEF LS50s; the 205 sends below 80 Hz to a pair of Velodyne HGS-10s.
