Network Acoustics Eno Streaming System vs SGC Optical Isolation System

Thank you @charles1dad for the response, and other replies.  Learning a lot about the 'in house' side of getting things best established for streaming.

I typically use wifi to stream from computer to Black Ice FX DAC, or to a Chromecast Ultra HD puck to stream audio and video to TV; and then thru Toslink into the DAC. I am wondering if I should be moving the cable modem closer to the audio system, (it's like 3-4' away) and then using the Ethernet out to the Chromecast Ultra which has an Ethernet in thru their power adapter (odd, I know).  I 'feel' like I am getting some very high end glare or high frequency sort of whistle regardless of streaming method or DAC, leading me to wonder if it's from the wifi/modem/cable integration to begin with?  

Very helpful info about the ground loop potential with distant set ups.  That made a ton of sense.

@mitch2 got it sorry..

Here is my finalized network setup. It uses a generic switch and generic FO converters. I found the final tuning came down to cabling, nothing outrageous, just good old trusty Pangea! Results : blackest background, spacious soundstage, boat-loads of air, transparency to source, and completely fatigue free listening. Nine little boxes, but who is counting because it works!

Splitting Hairs

I will get this figured out someday. Right now, simple seems to sound best; starting with modem and router (both powered by HD Plex LPS), then 45 feet of CAT 8 to Bonn switch (powered by LPS) then Network Acoustics muon LAN cable from switch to muon filter, then captive muon LAN cable from muon filter to Mojo server, then muon USB cable from server to Mojo DAC. This sounds better than any other front end configuration so far, even without the optical isolation.
