Another "kinda-newbie" head scratcher

@retiredaudioguy it stopped! I thought I had tried that before to no effect. But just having the turntable disconnected, eliminated the noise. Huh. I have Cardas phono cables on now, they replaced uber expensive AudioQuests when I first noticed the problem. 

My condolences. You have a frustrating problem.

I found the culprit. Power line ethernet extender. Soon as I unplug that the noise disappeared I thought I had it relatively isolated on an entirely different outlet but apparently it’s breaker dependent or something so . Thanks for your help guys I’ve got a new trouble to figure out. Namely how to get internet into this room. 

Great discussion great input great diagnostics

If your streamer can accept WiFi try that.  If not there are WiFi to Ethernet adapters (e.g. IOGear), usually WPS enabled so pretty easy to set up.  Plug it into an AC receptacle within a Cat5 of the streamer.  I used this for an Aurender streamer.
