I use a very simple and straight Setup.
A Synology DS 213 Air is powered by a 12 Volt SBooster
My Music is stored on 2 Samsung SSD Inside the 213Air.
Now the NAS is streaming the music direct to my Aries.
That means perfect isolation because there is no need for a switch, Modem or a expensive cables, etc, - oh yes, ... and it sounds very good !!
What are your sentences about this Setup ?
