Speaker Cable: Please Try This Experiment ?

[Ropeburn]

Did someone measured cables with difference materials before? Like gold, silver, copper wires because have some have lower impedance.
Can it impact sound? That i want to know.

See that tiny resistance difference between copper and silver? Some 6%.

If you have copper cables of, say, 3m, then replace them with silver ones of 3.5m, you made it worse. Because length is proportional to resistance and way more relevant in practice than the difference between the materials.

Is there a measurable difference? Of course there is. See the above post.

Does it impact sound? Not unless you are running a few hundred meters of this stuff. At "normal" speaker cable runs, i.e. 1-3m, the difference would be a fraction of a decibel.

Take away: just because you can measure a difference does not mean that the difference is audible. I can measure the weight of a single grain of rice, but eating an extra grain of rice isn't going to make you feel more full.

Nice copper and silver have almost the same. Did not know this.

You said "just because you can measure a difference does not mean that the difference is audible". Is this also the other way around then?

If you can hear it you can measure it,

Tungsten would be fun, and completely unmeltable, no matter how low your obstreperous speaker impedance goes. Shame it's so brittle!

The problem is when cables made from the same material can impact sound, you wouldn't know the difference is due to material or not.

Tank gun ammunition manufacturers hate this trick. They want to keep prices down on the metal.

As Keith said (the other Keith), if it's audible, it's measurable. But the question is whether you are doing the correct measurement. As Toole emphasizes over and over, humans hear differently to omnidirectional microphones.

No, it can't. The marginal difference in conductivity (meaning slightly lower resistance) of silver versus copper (gold is actually a slightly poorer conductor than copper) is irrelevant. And if you need something with lower resistance (say, for a very long run of speaker wire) you can do much better by simply increasing the diameter of the wire to get lower resistance. Gold plating is used for contacts to prevent corrosion (although it is poor for applications where the connector will be subjected to a lot of plug/unplug cycles as the plating will wear off).

Just use Copper Tungsten alloy Problem solved!

Every time I have experimented carefully with kit the principle conclusion has always been that nobody has repealed the laws of physics so I am not wasting any more of the time I have left trying anything pointless.
Sorry.

Don't be such a fuddy-duddy! This is all good stuff. HA HA!

Not subtle at all.

Ordinarily I'd complain about how completely nonsensical that AI generated image is, but I suppose that's apropos given the topic.

I remember about 4 decades ago there was a small (?) movement in the UK that claimed tiny solid-copper-conductor speaker wires sounded fabulous. In America where everything is "big as Texas" we knew this was BS. I never heard what happened to that movement. Did it just wither & die off (like the strangled signal to their speakers)?

You might be recalling DNM cables, designed by Denis Morecroft. He made various amplifiers, some of which I were made in Perspex or acrylic boxes.

I’m not sure if the business is still going, but there’s a website here. https://www.dnm.co.uk/index.html

I had some DNM interconnects and soeaker cables for many years from c. 1986 onwards iirc. They seemed to suit the gear I owned at the time, and I sold them for more than I paid many years later - something few wires achieve!

Well... I like to listen to them at right angles to the propagation of the signal.
Those two are a couple of Philistines, they are...
