To All Cable Deniers, 1 Very Simple Question.

@toro3 what you write is no BS, if you'll forgive the pun. May I offer a partial answer to your question of why people on hifi forums don't stick to answering the original poster's question but instead engage in caustic and tangential rants? It may be that grumpy old retired men tend to fight despair over their feelings of irrelevancy that develop after ceasing to work for pay by raging at the dying of the light, as Dylan Thomas did at his father's death. On the other hand, wise old men (who don't drink as much as Dylan Thomas), a group in whose company I hardly belong, more often remain quiet, gathering their limited energy to simply stay focused on matters at hand.

Back in the days a pair of RCA cables came with the cassette player, I borrowed a pair of heavy well made interconnects and the difference between the two was dramatic! So I’ve been a believer for maybe 45 years.  Having said this, I have never experienced such a huge change from power cords.  Yes I can hear a difference between that 18 gauge zip cord and a well made 10-12 gauge cable, but it’s no where near the difference as I hear with the throw away cables that used to come with tape decks, tuners, turn tables etc.

Question' I'm probably repeating someone else, but wouldn't a pure/near pure copper male connector be too soft, bend easily, for that purpose?

@vitussl101 You asked a fundamental question that is worth answering.

Yes, pure copper is too soft so it cannot be used as plugs. About 98% is the max you can go for a plug according to some sources. 

But some plugs have 30% copper. Average is 60% copper is what google says. 

So understanding the role of copper in a cable. And understanding why it cannot remain pure. The question arises, as copper % decreases, what then happens to the sound fidelity?

Do keep in mind, there are 2 ends in every cables, and there are multiple power cables in a system.

To the person(s) asking about why does it matter if there are hundreds of ft of wire are running in the wall. I’ll borrow the words of a man much wiser than I am to answer.

Misconception #3: There is up to a hundred feet of wire in the walls, so the last 6 feet of power cord can’t possibly make any difference.

Answer: “The power cord is not the last 6 feet, it is the first 6 feet from the perspective of the component. As stated in #1 the local current and electromagnetic effects directly affect the sonic performance of the component.”

It usually takes a wise man to point out the obvious. 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.
