Anybody use Innuos Zenith or similar server with Bartok or Rossini?

Hi all, thanks all…totally confused audiophile who does not understand lots of the network specs.

Simple question;
I have a Rossini Apex Player.
I bought the Innuos ZENITH MK3

I have a 2 gigabit cable provider set up.

How would you set this up? I am thinking ethernet cable from the direct wall outlet which goes direct to the router/modem to the Innuos lan plug. The my Silver Dragon moon Audo USB from the Innuos out to the Rossini? Run sense off my MacMini?
Thoughts and much appreciation to anyone who cares to pity and share a lost expensive music lover…
