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?

if you run a dedicated line, why not plug your amp into the grounding device/conditioner with everything else? The amp will benefit from it along with all other components.

as i said before, i got a 10-2 dedicated 20 amp line using atkore 10-2 cable. It is very well made cable steel sheathed. 750 for 250 foot line. They only sell in 250 feet. I have 125 left. I also run my best power cable from the dedicated outlet to my QB8 ( that cable is extremely important). Then every component plugs into the qb8. Its really not hard. It yielded great results. Everything was to code. I just followed the advice of someone who sets up systems all over the world and at high end audio shows. He just set up a huge room in Munich. Pretty sure he knows what he is talking about.

of course. My point was not at all about the qb8. Whatever conditioner you get will help. I was mainly referring to the dedicated line. Once you do that, your noise issues will settle down. You won’t care as much about the conditioner. Just have the electrician test the noise. We got .01, which is hopefully something close to what you can get. Also the outside world is just quieter after midnight. Its not just noise coming through the system. I am in a big city and the dedicated line helped a ton. I am sure it will for you also assuming you can run one to code. Just get a nice cable to run and Dont bend it. Have the electrician run it in a way that is clean. You will be fine. Cheers!
