I used a similar setup for ethernet for a while, but I've since adopted the Google MESH system. Router is upstairs. Roon core runs downstairs on Mac Mini with Ethernet to a microRendu and USB to Ayre Codex DAC. Roon bridge runs upstairs on an iMac with Ethernet to an Ayre QX-5 Twenty digital hub. The sound is superb, especially with Qobuz files.
