Power Cord Length

just a guess here but it seems to make sence...if there is any sence to be made spending big $$ on power cords. In an article i read about using the house electric service to run computer network signals they indicated that they put that signal into the higher frequency range since the noise on the system resides in the lower frequency. My guess is that some of the high end cords are acting as high pass filters to some degree so that the noise is removed before it gets to the amp. A longer cable may increase the efficiency of the filtering?

it seems to do with attenuation of high frequencies energy, as the noise amplitude in those Mhz range gets weaker when distance travel gets longer.

5ft is optimum for good signal flow and filtering.

Could you please explain what you mean by "signal flow?" Other than a cable that is of high resistance because of insufficient gauge, what would constitute bad "signal flow" in a power cable?
