Due to the fact that you are only supplying power to source components, you should be able to get away with 'less' than than if power amps were also included the circuit's demand. Experimentation is the only way to determine what will work out best. You could temporarily locate the equipmnent closer to the wall outlet (installing a quality outlet at that location) & connect to your Wireworld strip etc, then listen for a day or so to charactarize performance. Then move the gear back to where you want it located & try a heavy gauge extension cord. The above advice "fewer connections the better" is certainly valid; you could install a female IEC at the end of the heavy cord for connection directly into the Wireworld strip. However I would want at least *some* line conditioning so I would put a relatively inexpensive Chang Lightspeed 3200 'filtered 6 outlet box' or equivelant in place of the Wireworld. Don't get me wrong I like the Wireworld strip, but when I replaced it with a low current Chang for source components, the sound became cleaner & quieter.
Following the extension cord experiemnt, you could twist up a bundle of #12awg THNN wire into an "extension cord" attaching some good quality ends (Schureter or Marinco plug & female IEC) etc; there are others & I doubt that I spelled either name correctly so research is in order. For the next comparison you could make an "upgrade extension" using better wire from Kimber DIY series cable or other 99.99% OFC copper & compare that with the regular Vutron cord that you started out with. If I was doing this then that's where I'd begin (never mind the experiemnts just do it right to start with). Above all, just install a decicated line & forget it, but as was stated this may not acually be necessary.
