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.

Perhaps I missed the 'Physics' to which you are referring Grant. Where in the linked item did Caelin elaborate on why "longer is_always_better"? I read an opinion that he doesn't recommend PC's shorter than 3ft. That's not really a practical problem, since most folks can't place their gear that close to their outlets anyway.
Correct me if I'm wrong, but since none of the differences we power cable 'believers' hear can yet be verified by standard measurements, then any "technical" explanations as to why PC's "always" sound better in longer lengths is just theory attempting to support subjective experience, yes?
However, a person can easily buy measuring devices that will show that a shorter PC does indeed have superior electrical characteristics over a longer one of otherwise identical design. So it would seem the 'shorter is better' camp have more evidence on their side, for the time being at least.
Of course, you're welcome to your opinion, and in your context it may well be true that longer sounds better. I firmly believe in trusting one's ears as the absolute judge of quality.

On that point, we are in complete agreement.

Happy listening!
Zaikesman, if you plan to compare the effects of PC length, I'd suggest changing the PC that connects your power conditioner to the wall. By affecting a number of components at one time, the sonic effects of the change in length should be somewhat more pronounced. It also makes clear that the change in sound isn't solely due to reduction in EMI near your gear, or RFI filtering, since the PC should at that position be both farther away from your rack, and before the much heavier filtering of your powerline conditioner.
Differences of over 3 feet should be very easy to hear, while lengths shorter are useful for 'tuning' once you've got a handle on the difference length makes.
