What is everyone using for dedicated AC lines???

Stehno, we must have been posting at the same time. If Parts Express has 10 gauge OFC copper for about the price you quote, it must be considered as an option. I can't imagine better quality copper NOT providing superior results.

Wish I had known when I ran my dedicated lines. I may consider upgrading later.

I have great sound and I am using Romex brand 12-2 and 10-2.

Other option is 6 or 8 gauge wire and 240 volt, provided your amps may be switched. I got a small but very noticeable improvement both times amps were run in this configuration.

Even with 240 and several 120 dedicated lines, your cost will likely be less than buying audiophile power cords.

No question audiophile power cords are beneficial, but dedicated lines are a huge bang for the buck, even if you later decide to go for aftermarket cords as well.

Good to see you posting again Glen.
