Wi-Fi or PLC?

@tsmithpam  You won't need ethernet for streaming in Direct Optical, it is only needed to reach the web configuration UI on the speakers.
For volume control you'd have to use digital volume, like the one in Roon. Volume control in Phantoms is digital anyway so there is nothing to loose (maybe apart from convenience).
