Longer Power Cords Sound better?


In my quest for power cords, i have noticed that a longer cord say 6 or 8 feet tends to have a nicer sound in my system that the same models that are 3 or 4 feet.
Power cords i have found this to be true include Cerious Tech, Cardas, and VH Audio....anyone have an explanation?

AND by nicer sound I mean they tend to have a richer midrange, and a more coherent top to bottom presentation.
ie
I held an 8' and 5' power cord up to my ear and I thought they both sounded the same. I guess I'm not an audiophile.
Sugarbrie, although not practical, I have wondered how this would sound. Is that an example of AudioGONE dementia? Would you offer your beautiful Sugarbrie BC21 up for experimentation? Heheh.
Gunbei are you off your pills again? :)
I am waiting for a bucket truck to come so I can get busy soldering my new power cords directly to the pole, they are not Cryo treated but do cold Ohio winters count?
There is a very simple explanation of why longer power cords sound better. This is because they represent a longer proportion of the length from the power source (e.g. the power plant, dam, or whatever). Therefore, if I am 25 miles from the power plant, a 4' chord represents .003% of the total run, whereas 8' would be .006%. This is double the effect! Clearly significant enough to be heard with our audiophile "golden ears":)
Vince at Plinius swears by 10 foot length for power cords as sounding best, I have no idea myself...
