Here's a quote from the PS Audio website:
"The Power Plant concept acknowledges that we cannot control the quality of the homes incoming AC power, nor can we fully repair its problems. Instead we simply ignore the problems, start over and generate new AC, thus eliminating the problem entirely. There is no connection between the input and the output of a Power Plant."
So it would be double-speak to suggest that an upgraded power cord would have any effect on the output when also claiming that there is no connenction between the input and output.
