Hi All,

I ran into a Spanish forum some time ago, and found an explanation why cables can not alter sound...

The reasoning behind it is that an electrical signal travels with (let`s say, on average), 80% of the speed of light through a conductor. That means that, unless we're talking about really long cables, a waveform in the audible bandwidth, can not do a "full stroke" within the length of a normal sized interlink or a loudspeaker cable, and therefore can not be altered.

Maybe a rather far-fetched explanation, but it somehow seems feasible to me... Any thoughts?

Thanks,
Peter

Darn! It sounded so GOOD smile.gif

What amazes me is that all the companies that make hi-end loudspeaker-cable, interlinks and power cables actually accomplish this without any design specifications that include the specific audio properties that can be measured (or at least verified in some way) afterwards, let's say in Quality Control.

Do you see the minute differing design specifications published for brands of gasoline? For toasted oat cereal? 87 octane is 87 octane is 16 gauge copper is 16 gauge copper. Just because something can be measured does not mean it is relevant.

...But if the design goal is making a cable that, as close as possible, is capable of transporting an audio signal unmodified (a.k.a. a "better" cable), and there are no known measurements that can actually confirm this behavior, how can a company begin a development process for this?

In other words "Because something can not be measured, it does not mean it is irrelevant" either.
