Do powercords make a difference in sound?

Will 2012 end without Liguy ever getting his power cord test conducted (pun!)?

Here is what Liguy posted in 2001 in regards to biwiring:

"After reading these forums for awhile I can finally say that I am a skeptic no longer with respect to biwiring. I recently purchased a demo pair of Martin Logans from a local dealer and found that I did not have enough money to purchase a decent set of speaker cables. As I was getting ready to take the speakers home the dealer stopped me and offered to loan me a set of cables until I had enough cash (Great Dealer!!!) to purchase some cables. Well, when I got home I discovered that the Logans were easily biwirable and that the cables he lent me were biwire cables. When I auditioned the Logans the dealer must have connected the jumpers when I told him I was not interested in biwiring a set of speakers. I figured what the hell, lets give it a try. I connected everything up, popped in a CD and my mouth fell to the floor. Unbelievable. So from one ex-skeptic to anyone who has a doubt. Biwiring works, I am an EE and frankly do not care why anymore."

Is it perhaps possible that the doubt associated with power cords could be as misplaced as the doubt associated with biwiring? :)

But how are we supposed to conclude discussions when people simply disappear? :(

Doug, this is a power cord thread not one about speaker cables. And Liguy did not start this thread. It's been over a year. What can you expect?

Foster 9, I am well aware this is a power cord thread; I posted Liguy's comments to show the inconsistency of his acceptance of biwiring when he was initially skeptical to his resistance against power cords, though he has done nothing (seemingly) to conduct as simple a comparison.

I waited a period of time before posting my above message regarding his disappearance. It seems now that the discussion may never get finished.

It was finished the moment it was started !!!!!!

When and if Liguy performs his power cord test I hope that he will utilize better methodology than in the biwire comparison that is described in the paragraph quoted by Doug. Note that the jaw-dropping difference Liguy found, and attributed to biwiring, was between the performance of the speakers when biwired into his own system in his own room, vs. their performance when single-wired into the dealer's system in the dealer's room.

This was pointed out by several people in the original thread, and only addressed by him experimentally near the end of the thread:

I have, at the prodding of many of you who have posted in this thread, tried putting the jumpers back in and just connecting one set of wires. So here is the verdict. It still sounds great! But not as good as with the speakers fully Biwired. Even though the Martin Logans are not known for their bass, the bass is much, much tighter with the speakers biwired.

I have referred many times in discussions of power cords and various tweaks to how easy it is to be unaware of and fail to control extraneous variables, resulting in misleading or erroneous conclusions. If an EE and skeptic such as Liguy can make such a fundamental error, perhaps I've under-estimated how pervasive an issue that tends to be.
