To All Cable Deniers, 1 Very Simple Question.

There are people coming into cable threads and saying all cables sound identical. So I have 1 question for y'all.

Today, it is about power cords.

The end-plug, the metal part, the one you plug into the wall outlet. Without knowing the % of copper in the plug of your basic cable, can you absolutely certain say it sounds identical to a plug with 98% copper?

How about 60% copper plug vs 98% copper? Identical?

40% copper, Identical?

20% copper, Identical?

0% copper, Identical?

To wrap up, the question is very simple. If the copper % is different, would the 2 plugs still sound the same?

A bonus question, if a plug is 60% gold, will it sound identical vs a 98% copper?
