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 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.
Tplavas: Please forgive me when I note that you seem like you're coming from about 6 different places at once with your arguments. I glean from your posts that you feel: A) measurements will show that shorter is better; B) we cannot measure the effects of power cords; C) listening will show there's an optimal length that may not be the shortest; D) if listening does show that this optimum length is not the shortest, then you've got the wrong cord; E) offering technical explanations for what we hear with power cords is merely theorizing to support experience; F) technical theories support how you think I ought to do power cord listening tests.

I agree with you on one thing, with apologies to Grant, which is that Caelin's article cops out in the end (athough I liked some of the points he made before then) by recommending that power cords not be shorter than 3 feet, the shortest cord anybody offers anyway. That's bold. (BTW, I use some Shunyata cords.)

To tell you the truth, until only about 2 months ago, I probably wouldn't even have repsonded to this thread, because it would've simply struck me as silly. Of the cords I owned in different lengths -- which were all 3-5 ft. -- I just assumed they either sounded the same or that shorter would be incrementally better, but basically I didn't think about it. Then I got an 8 1/2 ft. cord as a good deal on demo, thinking I would try it out and buy a shorter length if I liked it well enough. It was instantly the best sounding cord I owned, and I began to suspect that length had something to do with it. So I got another one in a 5 ft. length, and do plan to formally compare the two once I'm sure everything's broken in and I get the time. FYI, I will compare them in all system positions, because I need to know how they perform where they'll be used, no matter what the reasons for how they do.
