This borders on extremely pedantic, but the difference in resistance between #8AWG and #10AWG is actually 37 milliohms at 100 ft. It’s an engineer’s curse. Sorry.

@kcleveland123 - that is very strange; thought 12ga to 10ga was close to 1.5mohms… have to look that up again, my apologies…
12ga to 10ga resistance difference = (1.619/1000)*100)) - ((1.018/1000)*100))
= 60.1mohms… I stand corrected…
10ga to 8ga is 37.75mohms; according to this AWG table… you are correct…
Just figured it out… 14ga to 10ga is 155mohms, that is why I was thinking 1.5milliohms…
That is a lot of resistance going 12ga to 10ga. My run was 65ft…
Single strand #8 is quite stiff and big. In my case I wired it to a breaker, ran it up through existing ports in the wall to my LR, and terminated it in a hefty EIC plug and stuck that in the back of my Regenerator. But that was back in my old house.

@badbeef - Oh, cool… all by code I assume… yeah, on a 100ft run going 12ga to 8ga is like close to 100mohms… neat when you think about the output impedance of the P20 is 5mohms and that is sourcing your amp power supplies… going the fat ass single run to the P20 is the ticket… for me I had a 14ga 15A multiple junctions duplex in that room so it was a huge difference going 10ga CB to duplex. Yeah - looks like 100mohms reduction in DC resistance on a 65ft run…
I can just picture one of us Nuts auditioning the sq of wire nuts. Nuts.

Solder the pig tail. It sounds better than ant wire nuts. But use silver solder.
sorry. i’m lost as yoozyul

Looks like the pic of some dude totally focused at differentiating the nut/no nut SQ… and got some data that is confounding… “what just happened” just sayin… that’s my story and I’m sticking to it… who are you going to believe your eyes or me… 
Cold weld it with die crimpers, no dissimilar metals, or diode boundaries.
You’re right, cold welding is the best connection. Should sound the best. I has some anti-cable speaker cables and they cold weld the bananas to it. I try to remove the bananas to put spades and no way, you can pry all you want but those ends where fused forever. Those were the best connections in the world.
I am in a condo, does running dedicated lines make much of a difference? Noting it is NOT as easy as doing so in a house, and probably cost prohibitive as they can’t run em in crawl space, etc…
@abeiklou - For me it was a given cause I had 14ga 15A multi junction duplex for the P20 source. Using a P20 w/ 20A capability was what I was after from the jump. 2000VA capable. I was not going to go with serious power cables to have to re-purchase 20A power cables down the road. You bet it made an SQ difference. Mostly in the low end tightness. Same as getting very serious 6ga power cords make a huge difference. That was one of the best SQ moves I made.
It is a noticible difference but not extraordinary.
One of those things you can live without until you hear it
As an economical starting point I’d change out the existing outlets to Hubbell 8300. You can evaluate the wiring when you make the swap. My guess is you have 14 AWG copper wire to an economy outlet. Apartments and condos of a certain era, 1980s to present are notorious for cutting corners on electrical circuits. Running separate feeds will depend on where you distribution/breaker panel is located and the distance to yor listening room. Also, if in a shared wall you may need to consult with your Condo Association and Declaration documents.If you choose to do it run two home run (direct from breaker to duplex outlet) circuits from the same phase (leg) of the distribution panel. With a qualified electrician you are probably looking at $400-$650 assuming you have two free spaces in your distribution panel. If you need to replace the panel go with SquareD QO series panel and breakers.
Condo is built in 2003, so not that old. The breaker is two walls away, an electrician said he can do it, BUT it requires cutting into two walls hence drywall work is required, which isn’t that costly, BUT it’s messy and difficult in a small condo with a baby due soon!
Are there any audiophile approved circuit breakers?

In the UK we have 240v ring mains and one way of avoiding problems is probably to have an audio system that does not need a dedicated nuclear power station, like Stellar. My house has the usual 15A mains flex and I don’t worry about it. When I had a regenerator integer showed more than 120w.
