Most of my power cords are of the DIY persuasion and I have a nice stash of Oyaide 046 and 004 plugs. I bought a few hundred feet of rather good silver plated solid core copper wire some years ago and have built several power cords of varying lengths, from just a couple feet to a few meters. I've used these on all my components over the years and yes, I have experimented to see if a short cord sounded different than a long with the same wire and plugs and I really couldn't discern a difference of any significance. There might have been the slightest of differences but, in my systems and to my ear, it was truly negligible.
