Help - static noise in speakers

I had a weird static noise coming through my speakers and discovered two things contributing to noise.  Ethernet  cabling near speaker wires and I also had to move e my ethernet switch away from my tube preamp.   Amp is tube.  

In my last house I had a Glade Plug In air freshener causing noise.   Whenever it released its scent I got a crackling noise through speakers.  Wasn't even on the same circuit.  Unplug any stuff like that while troubleshooting 

@mojo771 "Audioquest Red River" are these your speaker cables? I can't find any reference to that being a line of Audioquest speaker cable, interconnect yes.  Its much more helpful if you accurately include the brand and model of the equipment, you're using to help you troubleshoot an issue. Otherwise, most comments are relying mostly on conjecture.

faustuss - you are correct.  The Red River box was right next to the other one and they look almost identical.  My speaker wires are AQ Rocket 44

oddiofyl - you are correct as well.  I had no idea, but yes - when I moved the ethernet cable farther away from the amp, the noise stopped.  

Thanks to everyone who responded.  After all the troubleshooting, it was the simplest fix - move the ethernet farther from the amp.

Any noise due to external factors would show up on both channels, my best guess of OP issue is failing cap, resistor, cold solder, either diy repair or return to manufacturer, let them diagnose, this all speculation at this point.
