Where to Place Network Switch

+1, @antigrunge2 

Keep it short and use your best LAN cable between switch and streamer.  You can try the Ansuz switch near router to see if it makes any difference to your TV, blu-ray or receiver. My money is on switch near the dCS DAC using the best LAN cable. I am using a mass produced switch with iFI wall wart for TV, Apple TV, Blu-ray off Amazon and it does the job well.

Interesting question.  Not sure if the dCS Lina clock can work on the switch.  I know the cabling ties directly into the Lina DAC.  I’ll have to research that some more.

If the goal is to limit or eliminate the EMI/RTI from the cable, would make sense to put the switch, which is supposed to clean that up, on the DAC side of the cable. Right?

Switch won’t clean anything up. Keep the switch out of your audio system. Run a long cable from switch then connect it to LAN galvanic isolator and from the isolator use a short high quality Ethernet cable into your Lina. 

Get a switch that doesn’t use a walwart. I go from the router to a more enterprise switch that doesn’t use a walwart to clean up the sound before the streamer, then use the best Ethernet cable you can afford between these 2 devices.

I also have Ansuz products and they are terrific.  I have a 26 port router and coming from that I have a Shunyata Ethernet cable connected to my Ansuz then Ansuz Ethernet cables connected to my components (dac/streamer). Set up is magical. 
 

good luck!!
