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?

@mambacfa - Do you have a link to the paper? I can only find it for purchase. I did find another from later in the same year by the same author about time-domain effects of rca ICs, but no listening tests in that one.

@samureyex "The power cord is indeed the first 6 feet. People that don’t understand why this is, maybe grab the closest person next to you to ask for an explanation."

Can I grab You to ask explanation on why swapping first and last resistors in the AC power network should have any effect?

I don’t have much to add to the discussion on if or why, but I thought it might be helpful to point out that the last (or first) six feet connecting your equipment to your wall is braided cable (by code) for flexibility while the wire in your wall is solid core. The braided cable has different properties regarding inductance, capacitance and impedance (though that difference must be very small indeed) and all wires act as an antenna of sorts, both broadcasting and receiving.

Does this make an audible difference? While I have found that they do, the affect (to my ears in my system) was not nearly as substantial as other cables. And I didn’t find any difference in modestly priced cables to stock. Worth the spend? To some yes. To many, I would say no.
