Longer Power Cords Sound better?

"...twisted and beautiful".

My imagination is conjuring up the most diabolically gorgeous she-devils wrapped in scaled power cords.

Nobody here has posited a reasonable argument for why a shorter power cord would ever sound better (kinda like the phallic analogy, no?). Although I don't think "longer is better" can hold true without limit (ditto!), and obviously for the vast majority of systems we're only talking about a range of a several feet difference at most, still it only makes sense that if a power cord does anything good for the sound at all, then it needs some length to get that effect accomplished. Of the power cords I own, two varieties (from two different brands) are in more than one length (ranging from 1m to 2.5m), and although I haven't done rigorous audition tests comparing the sounds of the different lengths (instead just going with whatever length works best from a cable-routing standpoint), my general, informal impression is that the length-is-good argument actually does have some degree of sonic merit to it. If I decide to do further listening investigations, I'll report the results here...

you mean the TV remote in our bedroom doesnt eat batteries every 3 days? say it aint so! :(

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.

Ahh, men with lots in common. Can't beat it.
