good discussion on power cords

"First of all, power cords do not transmit audio signal - unlike speaker cables that transmitting audio signal."
"The power cord soul purpose is to transfer the power from the wall outlet to the equipment".
"How is the last few feet of cable can really make a difference?"
A few quotes from the video that are completely misleading.

The late Charles Hanson once said that an amp is basically a modulator of the power supply.

He also has another video that says expensive speaker cables do not make any difference

but I think we can state pretty unequivocally that the goal of the power supply is to isolate the output (audio) from the input as best as possible.

I would disagree with that statement.  There is really no "isolation".  They are all related.

Technically the diodes in the power supply perform a modulation function on the incoming AC which is why you get DC.

I think that is called "rectificatioin", not "modulation".  

With regard to the "Audioholics" vid, I actually agree with most of what he said on his other videos, but he probably is wrong with respect to power cable.  

^^^ Well it seems like you're disagreeing with Charles Hanson who is actually a real designer ... sigh ... face palm ...

Your description of rectification and modulate makes me laugh so hard.  I suppose until you understand the difference between "rectification" and "modulation", there is not need to argue with you since it would be a waste of time.  

^^^ OK, whatever, so you're a pretty good at copy and paste.
