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.

Cables have their rated electrical parameters specified per unit length, typically per foot or meter. As such, their level of capacitance (for example) will increase linearly as the length of the cable increases. Therefore depending upon a cable's specific design parameters, different lengths can offer some significant differences in apparent sound quality. In some systems and applications higher capacitance in a power cable may be a desirable attribute, while in other scenarios it may not. The same applies to a cable's rated inductance and resistance. YMMV applies well with high end audio cabling solutions.
