Where is a good source for cryo'd wiring? Solid or stranded, whis is better for this use. So far the only place I've found is JPS labs at 1.50 per foot each. If you make two 20amp runs, any harm in having a common ground for both outlets? Grounds (and neutral) always wind up on the same buss later anyway.
Isolated or dedicated lines for audio ?
Re wiring all 3 systems in my home for audio. I have one side claiming its best to do an isolated and one side claims dedicated lines are better . i am no electrical engineer and want to do this once , right . There will be 3 lines / outlets per system. Thanks for any input!
