Ethernet-wired setup of Phantom stereo

[Mohmm]

I am considering to purchase 2 Phantoms (perhaps Silver) for a stereo-setup in a new appartment. Source will be a Mac Mini running Roon.

What will be the correct way of connecting the three parts of the system:

Mac
Dialog
2 Phantoms

I do have an ethernet port close by. If I want to have all parts including the Phantoms connected by wire, I probably need to use a switch?

Thanks
