Power cords

Is there any truth to the following which, as you can tell from the quotation marks, is not my brainchild (my brain is childless...). I picked it up from the site of a well respected amplifier manufacturer and trust I am not committing some sort of legal or moral transgression by reproducing it here:
"When you plug your power cord into the wall outlet you are in 'SERIES' with all the wire on the other side of the wall all the way back to the power source. The small length of power cord from the wall to the amp is insignificant compared to the miles of wire it is connected to. As long as the power cord can deliver the current and voltage required to drive the amplifier to full power it is as good as it can get."

Would like to think power cable is part of you power supply CKT. The resistance, capacitiance, inductance, and RF shielding on the input side of your transformer may play a subtle role of affecting the regulated voltage in your amp or DAC. And the result is it sounds different for different cable/amp&DAC combo.

Can't figure out a simple equation or ... for a useful engineering prediction. If somebody knows, please post.
