Thanks to dimora and turnbowm for introducing technical analysis into this discussion of the benefits of high end power cables. I firmly believe that science should be the primary factor in deciding how lovers of pure sound reproduction should spend their money and set their priorities in making their purchases.
As I mentioned earlier, "I am very skeptical about the actual benefits of the host of fancy expensive power and speaker cords out there. The first thing I notice about the ads and write ups for these devices is the lack of any hard technical performance data - such as improvements in distortion, frequency response, damping factor and noise levels."
In terms of power cables,
dimora
correctly pointed out that the house wiring leading to the actual power cable could entirely negate any benefits of an elaborate cable shielding or configuration. In this situation, a power conditioner, coupled with quality standard cable would make a more sensible spending choice.

could find no valid justification for large expenditures on power cables, other than assuring that the current carrying capacity was generous and the quality of the contacts robust.
My “Handbook of Instructions” for my Marantz Model Fifteen vintage power amplifier, makes no mention of replacing the “stock” power cords of this dual unit - and again recommends using ordinary 18 gauge lamp cord for speaker connections up to 30 feet and heavier gauges for longer distances. A unit of this outstanding quality, would surely have suggested using upgraded cables - if “perfectionist” audio designers Sid Smith and Dick Sequerra had any concerns about compromising its performance in any way!
I am again questioning the rationale - other than pure subjective judgement - of expenditures that could be better diverted to more quality electronics or mechanical components in the system. In that case, technical or scientific data could be fully employed to guide purchasing decisions - rather than vague claims by the cable manufacturers to justify their outrageous prices!
