The OP @imaninatural mentioned a desire to move from wifi to wired. It was not stated what his/her reasons are. Is it in the hope of better audio quality? Or is it because the wifi has hiccups?
Hiccups can probably be mended with a wifi extender or a wifi-mesh setup.
I would not put my hopes up for improved sound quality if there already is enough bandwidth for lossless streams. They will reach your Bluesound Node without error, otherwise your Bluesound would not be able to update it's firmware without error.
