Why anybody would convert Ethernet to usb into a dac/streamer is nuts, going backwards in sound quality. Ethernet into the dac will always sound better than usb, anything sounds better than usb!
I wouldn’t use any switch with a wall wart power source going to my dac or streamer. I go out of my mesh router into a switch that has the power source built in, use an Soundstring power cable into the switch, and then into the streamer using a cat 7 Audioquest Vodka cable, then using a Revelation Audio $700 i2s cable from the streamer into the dac.
Check out some reviews on going thru 2 switches that clean up the sound that sounds better than going thru 1 audiophile switch, and they liked the sound better going thru 2 cheap switches. I’m doing this but using a better switch that doesn’t use a wall wart power supply.
At an audio show, a dealer was doing a a/b comparison between an expensive $2000 audiophile switch and a typical switch and I thought the system sounded better with the cheap switch.
I just saw a video of someone going over an audiophile switch which was a rebranded d-link (the case had d-link pressed on it) switch with a couple caps installed for $700 more. If you want to eliminate any noise into your streamer or dac, convert the Ethernet to fiber then back to Ethernet at the streamer/dac.
