No. My first thought is 'what's the wiring like inside the wall on the other side of the receptacle' ? Not to mention dimmer noise, fluorescents, sagging / surging voltage, the ice machine is on the SAME circuit, and there's only two receptacles for the whole band? Doesn't fix any of that ! Regardless of your AC cable, it's only as good as what it's getting from the wall, and often, it could be a lot better, which this won't fix.
This reminds me of those $1000 a foot speaker cables. Then you open up your high-end speakers only to find cheapo 20 guage wire from the crossovers to the drivers and a solder job that looks like it was done by a crackhead.
