I assume you the cable router could go almost anywhere? Is there a reason why it is at your audio equipment? All you need is an Ethernet cable run from wherever it is to your audio rack.
Ethernet is an electrically isolated connection. It is not perfect, some high frequency noise can get across, but whether that makes a difference or not would be a matter of your Streamer/DAC. Listen to a silent passage, is there obvious noise? No? Unlikely to be any issue.
