Depending on the length of your run, I would buy an audiophile "in-the-wall" cable.
If you have a long run, (mine was 100') that will be cost prohibitive. Use a metal Shielded cable to avoid RFI or run the wires in metal conduit, and use the heaviest gauge you can. You can even use 10 gauge for a 20A circuit, though 10 ga. will take more current.
Use one length of wire from your main breaker panel to your outlet. I wired direct to a gang of outlets to make a power strip. Then use Hubble or similar (Hospital Grade are about $16 each) duplexes.
Enjoy.
