Audible Differences in Copper vs. Silver Cables? - Page 14

In the electrical domain, the audio signal exists as nothing more than voltage and current versus time. So you have a time domain and a frequency domain. In order for a cable to make any actual audible difference, it must alter the signal in the time to main and/or the frequency domain. And we can measure any alterations in each of these domains to levels orders of magnitude lower than our ability to perceive. And it has been shown over and over again that unless a cable is broken, or incompetently designed, it will not alter the signal sufficiently in either domain as to be audible.

To put it bluntly, getting an audio signal from point A to point B without any audible degradation has been a "solved problem" for probably close to a century.

And the copper/silver/whatever debates are particularly absurd. All a wire brings to the table is its conductivity, which on the applications side of things manifests as simple resistance. And a given amount of resistance is a given amount of resistance regardless if it's from a copper wire or a silver wire. There is no otherworldly property that distinguishes the two.

First of all, I was not staying that there is definitely a difference between copper and silver. I was merely saying that TheoS53's tests (while interesting) don't demonstrate there is no difference. 

 

Second, I myself am agnostic about it. I know that I got much better sound from stock cable after upgrading, but this is likely due to "good copper" versus "bad copper." 

 

But in the end, no amount of theorizing will settle the issue, because there are always potentially things we are failing to measure. You'd have to perform a blind test a statistically significant number of times to come to any meaningful conclusions.

Ok, I too didn't state it as a fact that there is a difference. I specifically said that, according to the results I got, it seems that that might be a difference..but thats a the difference between finding proof, and having results that suggest something

Fair enough. Sorry if I was too argumentative. :)

Fair enough.

Not sure what that means.

Not without some Nobel Prize-winning paradigm shift in our understanding.

And there's also difference testing, in which signal A (which could be passing through a copper cable) is subtracted from signal B (which could be passing through a silver cable) and has the advantage of being able to use actual music as the "test signal." If the residual isn't audible, then there's no audible difference between the two. Pretty simple.

If you wanted to show that there is an actual audible difference. Otherwise, a null result is just a null result.
