Perspective.
it is all about perspective. We all know that an analogue music signal is alternating current but in the spectrum of used electronic frequencies it is practically DC. This allows us to use Ohms Law and other simple equations derived for the use in direct current circuits to calculate wattage and current with minimal error.
It is important because many of the (scientific) effects used by cable manufacturers to promote their products are only really important at frequencies orders of magnitude higher than audio.
RF issues, surface effect, grain structure etc are all real but of minimal effect at audio frequencies, for example, RFI interference has such a tiny effect on interconnects that companies like Nordost, XLO and DNM routinely make and sell cables that are entirely unshielded.
In reality cables can and are designed differently but unless they are deliberately engineered to sound different by measurably altering their electrical characteristics they will sound pretty much the same.
Subjectivists will tell you to trust your ears as differences between cables are easy to hear, and yes, most of us have heard these differences. However these are sighted tests only, when such tests are carried out blind, the differences effectively disappear.
There is plenty of evidence of this if you care to look and very little to show that the differences can be reliably heard. Subjectivists will point out that such test conditions are compromised, different system, different room, stress on the listener etc, etc, such that the differences become harder to hear.
That is the argument, you decide for yourself which side you are on.
re your point about subjective observation..that we can hear a difference between cables/interconnects? You then ask us to accept your premise that on blind testing? That no difference could be heard? Sorry I don't accept your premise..Ps you present your premise as if it's a fact? It isn't! Then ask to make up our own minds? Based on what? Spurious facts? When I write my drivel I always try to say 'in my opinion' Or 'in my view' makes me sound less full of bluster! Less 'know all' I'm am subjective..i listen with my ears..in my view people with high quality equipment who use cheap cables /interconnects are foolish...
As this is hardly the first cable thread on this forum, I had rather assumed that contributers had a rudumentary understanding of the subject, Ie understood the differences between sighted and unsighted tests. Clearly not so, so my apologies.
There is plenty of evidence that supports my 'premise', so much so that that I took it for granted that most hi-fi enthusiasts would be aware of it, clearly an error on my part.
I did not qualify this 'premise' for the simple reason that it is not an opinion, but a fact supported by a quite substantial body of experimental evidence. There is no comparable data that shows that listeners can reliably tell the difference between competent interconnects, or for that matter speaker or power cables.
As a starting point for learning about this subject I suggest the following thread which gives several examples of blind testing of cables (and other components). There are plenty of further references to be found within the thread.
