"This of course, should illustrate why the myth of "miles and miles" of power lines is just that, a myth born out of ignorance of the actual situation, and the oft repeated mistatements of some who have a hard time actually thinking about AC power issues, and what is going on."
Respectfully, it does not illustrate why one should spend hundreds orf dollars (or ebven over a thousand) on a power cable when one can simply install a good line (ie. 10 gauge) from the mains to a dedicated outlet --make it isolated ground. Total cost about $100 plus electrician. And it can feed your whole system
The lossses attributable to the last 3 feet are negligible anyway.

Even with four #10 gauge dedicated circuits for my system, power cords make non-trivial differences. Unfortunately each device likes different cords. The good news for me is that the most expensive (> $1000) cords that I have tried sound worse to me than the more moderate priced cords (say $300 - $600) in my current system.

Your response completely ignores the aspect of the power cord either radiating, or picking signals from other power cords or any of the other cables, including video or digigtal feeds.
This was touched upon in the referenced URL's. It might help to actually read them.

  I am not ignoring that. You did yourself in your post. Read it again. You are arguing that the typical argument about long lines of cable before your expensive power cable is absurd, and then at no point do you say that the reason the expensive cable sounds better is because of RFI. Rather, you explain that there are losses between the mains and your outlet.
  Perhaps a fair point if you have a poor installation. But an expensive power cable is an asburd solution.
  OK, now you raise the issue of RFI. Frankly, I have yet to read a single white paper describing how a particular power cable filters RFI that makes sense to me (sorry, I had read yours, as well as Caelin's, etc.). My experience is that with an adequate installation all well designed (not too hard) power cables sound the same. Please respect that.

    My previously posted and referenced URLs commented on a great deal, of which radiated noise, RFi, EMI, etc were covered. Only in the test of the last post, this one:
    http://www.audioasylum.com/audio/cables/messages/82423.html
    do I only talk about the line losses ONLY.
    If the supplied post URLs do not make sense to you, then either I have failed at my laymen's explanations, or you are not geting it despite the layman's explanations.
    I can respect someone's experiences, but that would have to include on your part having tried numerous power cords under varied conditions, etc., and having experienced a dedicated run on the same system, vs. the additional use of high perforance power cords, as well as having heard numerous power cords on other ssytems under diferent conditions.
    Perhaps your mains are relatively clean, and you have really nice cable layout in back of your equipment. Regardless, your conclusions probably only hold for your system, and not necessarily for others.
    I have done the above with all types of audio cables and with power cords. Each system reacts differently, and some equipment seems relatively immune to power cord/mains issues, and each component reacts differently to different cords.
    As for an "adequate installation" of the mains, this is the exception rather than the rule, and basing your statements on some utopian ideal is not very realistic.

    You're absolutely right. There's a load of garbage spoken about mains. See my reply to Jon a few inches up the screen!
