Where to Place Network Switch

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!!

Why people don't isolate wifi entirely from audio system is a mystery to me, wifi shouldn't exist on audio system network, routers with wifi enabled and then adding another component (switch) is not optimized network for steaming.

According to the Audio Group Denmark page, 

Clean streaming signal.
The Ansuz PowerSwitch has been designed with the aim of delivering a very clean streaming signal to the hi-fi system. To achieve this, Ansuz employs its most advanced and truly groundbreaking audio technologies of noise reduction and resonance control. Ansuz audio technologies ensure that virtually no noise is transmitted from the PowerSwitch to the audio components.
 

I believe I am on the right track here.  

@pgaulke60 the way I read it is do no harm was their goal. Hopefully they accomplished it. But once again if you think a switch will function as a filter and clean up your signal, it won’t. Cleanest way to implement the switch would be to have it plugged into another circuit and out of your system. As I mentioned earlier.
