Thanks Greg, that then sounds like a plan. That is, use my Ubiquiti switch’s SFP port and then just one SFP transceiver. Keeping it all in the IT closet is as you said: “easier” and for me, less than having 2-SFP’s and cable spices (if you will) being visually obtrusive in the audio room.
Cheers, to everyone who contributed to this thread. I had initially read about this sort of isolation on the Audiophile Style forum. But never implemented it. Having input from dCS owners adds gravitas to the premise.
I’m especially happy to hear that by plugging an un-shielded cable into the Keystone in my audio room that terminates an in wall shielded Supra CAT 8 cable, will provide the un-shielded input that dCS’s Andrew (as well as others) have suggested for dCS DAC’s like my Roissini.
I also benefited from several suggestions made, by purchasing a Belden Cat Snake Un-Shielded 5e Cable direct from DesignaCable. They’re inexpensive, Belden wire and well worth a try!
