People wonder why electricity runs through hundreds of feet of wire and all of a sudden you expect your short 6 foot piece of cable between the wall socket and amp to make a difference!!!
Well really thats a logical question, and i can see where people would think that way. Ive thought that way myself before. But also, everything with sound has to do with resistance, capacitance, inductance, etc.
So......if the capacitance and inductance is in a certain ratio over 100's of feet of wire, but all of a sudden through the last 6 feet, it changes ; Wouldnt that make the power supply in said amplifier transform the power differently? And if the amplifier being powered by that supply is powered in a different way, it can also sound different.
Alot of an amps sound does come from its power supply, like adding external power supplies to an amp rather than using the stock wallwart.
Bob Carver (Carver Audio, Sunfire, etc) did alot of research and testing with power supplies on his amps, and was one of the pioneers of Class H topology, utilizing rail voltage supplies in his amplifiers rather than huge transformers coupled by large capacitors, which took up space, were heavy, and caused heat.
His amps were very quick and had alot of punch because of this, but were very "wall dependant" in that they needed good ac current sources to work, and DJs using his PRO amps would sometimes work a venue with crappy wall outlets and their sound would suffer.
Alot if Carver amps did only come with a thin permanantly attached 2 wire cord though.
His more expensive amps had a removeable 3 wire cord.
If you change the capacitance of the AC cord, then your power supply will see the power differently and it still uses the same formula to change it and feed your amp. It doesnt know that you changed any perameters because it was built a certain way.
You would have to use a digital computerized brain in the supply to read changes and make adjustments to keep everything the same so the ac line and power cords wouldnt affect it.
There still is no need to spend rediculous amounts on cables though, because its only a matter of trying different cheap cables until you find that magic capacitance that makes your system sing, but cable makers know this and they make their cheaper ones with certain capacitance values, and make their better ones with other capacitance values, knowing youll hear the difference and swear that $100,000 cable is much better quality and worth the price.
All you really need is good hospital grade wall plugs and wire of different gauges, and types and try them until you find the magic number.
Ok, throw eggs now.
