I am not an electrician, but if I was building the ultimate system I would use 2 to 4 gauge power wire fitted through conduit. Would it make a difference in sound, who knows. But I like the idea of having everything overbuilt. You can get a 100 feet of 4 gauge from powerwerx for less than $500. If you are going to redo your internal wiring why skimp?
What type of wire for dedicated 20A AC lines?
I’m about to have two 20A dedicated lines installed. What type of wire should I use? I know there are differences of opinion on whether to use 10 AWG or 12 AWG, however the link below makes a great case for using even 8 AWG solid core copper on longer runs like mine will be (50 ft), to ensure a lower resistance, lower voltage drop over the long run, and therefore more access to instantaneous current for my Gryphon Diablo 300. The wire would need to be stepped down to 10 AWG to connect with the receptacle. The article actually states that the thickness of the wire is more important than the fact that it is dedicated…
Assuming I want to follow this advice, which again makes sense to me, where would I find such wire to give to my electrician?

I ran #2 wire to a sub panel and then made 2 runs of this stuff: https://www.gigawatt.eu/produkt/in-wall-cable-gigawatt-lc-y-3x4-mk3/ Along with Furutech GTX outlets, this wire has made a very positive impact on my system. It has brought my Coda #16 to life. |

@cleeds Since the OP simply stated he was running two new lines and did not mention any special conditions, I have assumed this is standard in home/wall wiring. Yes there may be other considerations if this not the case. I always assume the local building codes will be followed. Other than that I stand by my comments. Cheers. |
12/2 NM Copper Wire. Available at any DIY store. All you will ever need to meet code and run 20 Amps. Go to 10/2 if it makes you feel good, even though there is probably zero benefit. You system can only draw so much current and the 12/2 wire has no problem providing more than that. All this talk about about exotic cables, or going to 8 gague is just noise, and isn't that exactly what you are trying to get rid of? Would you pay for an 800 HP engine in your car if the local speed limit never exceeded 30 MPH? Than why would you pay for cable that you will never benefit from. Maybe this whole argument is becoming a macho "my cable is bigger than your cable" thing? There's some compensating going on in this thread. 🤣
