For loudspeakers wires, we can conclude that using an expensive metal like silver is just stupid, as we can have the same properties changing the geometry of a coper wire. (flat wires, etc.) And it is the same with isolator material.

The only interesting thing at the end will be the response curve. Yes, the wires can change VERY slightly the response curve of ours systems, but it is a better way to change this response curves, more economical and where we can manage it the way we want. It is the amplifier's or the loudspeaker's side.
We have to remember that, with wires, we are talking of changes less than 1/10 db between 0 to 100 000 hz, here, while our Speakers and listening rooms are not linear in a scale of 10dbs and much more.
And we have to remember too that 1db was set this scale to be near the littlest difference in level a human ear can notice.
We knows too that air temperature and humidity changes will have more noticeable acoustic effects than cables properties.

Buying a XXX$ cable is just insane. Better put those $ in better speakers and amplifiers and acoustic treatment of our listening rooms.

Dear Eperado,
Not necessarily so. Each material gives us a sound effects.
But Basic must copper and Silve is less .It is art . Bests

in a flute or trumpet's body yes - in wire/cable that's a very dubious proposition

one could adjust geometry between Ag and Cu wires for near identical LCR, even proximity/skin effect could be made very close

if you matched these parameters to ~1% over the audio frequency range and the cable effects were responsible for less than 1 dB response variation with a given loudspeaker you are at least a order of magnitude below demonstrated audibility of frequency response threshold

Depending of his color weight and price, if you like.
Don't forget that it is important to fire-up your system for the first time, before the burn in ceremonial, by a full moon night. A lot of people are not anough aware of this.

Actually I was very successful for DIY RCA connection .
Can I change the sound custom .
I Will inform you later . Bests

Did not electromagnetic fields respond to the same laws than the light, just wave lenghts, between 375 – 750 THz ?
If yes, how to call the equivalent of photons in the 20-20 000 hz range ?

I did not understand your response.

There are machines which bring electrons very close to light speed, but they do so in within a tube which has a vacuum.

Within a wire, these speeds cannot be approached.

It is not helpful to talk about photons in the 20-20kHz range, as their individual energies are so low and most of them will be virtual photons too. At low frequencies (=low energy per particle) the wave model is the appropriate thing to use (or the quasi-static lumped circuit approximation - we call it electronics). Photons start being useful somewhere around terahertz to far infra-red.

Are you (Esperado) confusing photons and electrons?

OK lets get this straight:

Brown is best for Country,
Red is for Rock,
Orange is for Silly Children's songs,
Yellow is best for Jazz,
Green is best for Folk,
Blue is for the "Blues,"
Violet is for Techno,
Gray is for Marches,
White is for Classical,
Black is for Gospel.

Of course, it was a question. Not about the electrons but about the quantum theory for electromagnetic fields.
I have no idea of what can be the equivalent for Photons/Bosons for waves between 20-20 000Hz. I know, it is a strange question. But i believe in some kind of unicity in the nature's laws..
