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.
