Dedicated 10 gauge NM-B lines twisted or straight


I’m not sure if it matters, but I’m going to run three separate, but parallel 80 foot, 10 gauge lines to the receptacles in my listening room.  I plan on spacing the wires about 12-24 inches apart, but I was curious if anyone has an informed opinion or insight as to whether it would make a difference to have each line twisted some, or flat, as I think most electrical wires are installed flat, to make them easier to pull.  Twisted wires supposedly would reduce magnetic fields, but I don’t know if it would then cause other problems, such as increase capacitance.

Don't twist NM, waste of time.  If you want to twist, use metal conduit with individual conductors. 

Also, maybe consider instead of multiple 10 gauge runs do a single 4 or 6 gauge runs to a subpanel.  Lower voltage drop, plus you can put an extra in-panel surge protector near your gear as well.

Thanks for the recommendation.  I don’t remember where, but I remember watching a video, or reading an article that demonstrated that the NM-B wire provided the best signal propagation with the least amount of signal interference (not sure if it was magnetic interference or what exactly) including compared the MC wire, but I don’t recall the source at present.

I followed his recommendations to great success. I used 8AWG with Furutech GTX-D NCF(R) outlets (accepts 8AWG wire). I also went the extra step of having the outlets, 20A breakers and wire itself cryo treated (why not). My electrician used some kind of grey flex conduit (not metal). Made a big difference for my system.
