Connect cable modem/router to different circuit than audio?


I just got some reversed polarity outlets in my listening room fixed and have a much closer plug for my gear.
I cannot (yet) do a dedicated line. Up to today, my cable modem was plugged into this circuit. There is a way I could put that on a circuit  apart from my audio if it had the potential to add significant noise. Is that something to worry about or would it not matter much? FYI, my wife's office lights, computer, monitors are on this circuit and there are some light cans, too. Just wondering if the router/modem is an especially big source of noise into the circuit?

Thanks for any opinions.

Sure djones51, I listen too, I'm just too lazy to do anything about it. ;-)

The router should not be on the same circuit as your audio.
A router with the coax line feeding it from outside generates high levels of RFI which translates into noise, an audible amount of noise.

Since you can’t isolate your audio from the electrical devices you mentioned, a power conditioner or power strip with filtering would be in order. Brick Wall or Surge X are very effective conditioners or a Furman Power Station will provide filtering from RFI/EMI noise on your shared AC line.

You have a very nice system, isolating it from the noise-generating electricals will provide noticeable benefits.


If you can't separate them, I suggest a Furman PST-8 as a good noise filter.  Put all your noisy devices on it.  Alternatively, you could get an iFi power supply for your router.
Thanks, all. I can easily put the router on a different circuit.

Presently, I have an Audience Adept 2R2p conditioner at the outlet (a Porter port) and in one of those plugs I put my DAC and the rest goes to a Wiremold power strip with a Shunyata Defender plugged into it.


If you can do it you should I moved my router closer to my system because I had too and it started creating noise in my system. As soon as I moved the router farther away the noise stopped. It’s a real issue anything you can do should help.
