The Physics of Electricity


Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?

Almarg, I know you have answered these same type questions with the same answer many times. Keep it up! Maybe cut and paste. Although no one seems to be paying attention it makes the most sense to me.

Thanks,

I don't think the OP of this thread is necessarily a troll. They did buy cables, and may be looking for something as to what they should hear, and why. Understanding it isn't easy unless you understand some electronic technology. The science and theory is complicated for most.
Llanger, I'm afraid this is not the right website for this question. You'll just have to leg it to your nearest physics department if you want an answer.

Here, there are too many people making real money selling these cables. You know how people get when you mess with their meal ticket.

I've even managed to receive lectures on quantum mechanics here, even as the "lecturers" admitted that it was not their field.

I don't know a single physicist that spends money on magic cables. There must be some somewhere...

The astonishing thing is that if cables made the difference claimed by the $1000 magic wire crowd, it makes you wonder what they are doing wasting their time with audio, they should be rewiring hospitals and nuclear power plants, it seems.
Mostly everything I hear can be measured. I think we need to try to come up with a way of interpreting these measurements, or new ways of measuring, but that is easier said than done.

Sometimes these cables can measure differently in and out of systems.

A cable carrying a lower level signal will usually be easier to identify the difference. Also, a longer length may show more of an audible difference.

Those throw away cables that come with some equipment usually deserve that description.

I've had cables that were over a hundred dollars that made noise just moving them. I'm guessing music vibrated those wires, and added some bad audible characteristics. Some throw away cables did it so bad, I did through those away for sure.

Anyone who has heard those early commonly used speaker cables that were 22 to 24 gauge wire can see why there are good and bad cables, that can make a difference. If you could get a 20 to 30 foot length of this stuff, Try it. You may be surprised how bad something can be, even if cables now sound the same to you. Cheap 12 gauge sounds so much better, it's unreal. So that shows it does exist.

Glass Audio, or Audio Express I believe, was the one who measured new cables (some years back) for a big box stores in house brand, and they had a lot of distortion. They looked good though, and I wouldn't want them in my system, even though they looked nice.

Now comes the 100 dollar, vs. 1000 cables. I'm usually satisfied with cables that cost a lot less than thousands. This is where I find than something else in the system will give you more in return. Or buy a second system for a bedroom, or somewhere else in your home.
Trebejo, Jim Thiel had a degree in physics, and though I can't say for sure that he actually spent money on magic cables, he did have some prefered cables that he would diplomatically recommend for use with his speakers.
