Network Switches

If you're worried about "ground plane noise" or other such nonsense made up by people determined to imbue digital audio with analog traits just because they understand analog on account of having been doing it for 70 years, whereas digital frightens and confuses them, the solution is simple and inexpensive. 

Use SFP for the last run into your streamer. Voilà! Problem solved.

Looks like the the iFi LAN ipurifier pro and the effe unit both run the signal through a transmitter, a receiver, and a short length of fiber. This works well, and it is essentially the exact same setup @deep_333 described in one of his posts above, except all components are integrated in a single box, which is more convenient and less unwieldy. It also costs $299 instead of $40ish.

Also, discrete components let you have any length fiber run you need, handy if you keep your Internet gear in a separate room.

This forum needs a facepalm emoji in order to deal succinctly with the toxic delusional nonsense being spouted.

Who wants to waste words responding to $2000 network switches - used, no less? Since when has "audiophile" become synonymous with credulous & benighted? Do we have to explain EVERYTHING ten times over? This is becoming tedious. Emoji, please.
