Stand alone DAC connectivity is a bitch

Having learned more about ethernet noise issues, i am finding solution is difficult.

i need a network bridge and an audiophile grade switch would be nice too. Dont want a network player.

Curious to know how you connect your dac to your system. I connect my router to a nucleus via ethernet and then to a dac via usb cable. I want to eliminate nuceus from between dac and router, and hook it directly to a switch.
