Dedicated 20 Amp Line for Audio

So now Michael Fremer is crapola. Wow. A new low. 

I ran 4 seperate 20A lines to my room. Recommendation of my daughter in law and she is an EE. 

Thanks to all. OK, I think I’m going to run two, 20’ long, dedicated lines. One for analog & one for digital. Both of those on the opposite rails to that of "noisier" items on the panel.

14/2 I presume and is Home Depot stuff OK?

Someone in a past thread recommended armored cable, maybe overkill?

Remember when you get ground loop hum, move the phono over to the same as everything else.
