"It's in the very last feet that the electric particles/waveform gets shaped prior to entering the audio component. As such, there will be a profound influence on sonics."
This is nonsense and technically incorrect. Just because some saleman says does not make it true. The network created by the conductors from the transformer and then from the panel to the outlet and then from outlet to the component all contributes. You can easily perform a SPICE simulation on this simple model.
There is nothing magical about the last 6-10 feet of wire unless perhaps it has a transmission-line termination in the plug or on the cord. An added network of this sort COULD prevent/reduce high-frequency reflections or resonance on the overall wired network. Whether transmission-line effects occur and if so, whether they would affect the delivery of power is debatable and difficult to prove.
