Do speaker cables need a burn in period?


I have heard some say that speaker cables do need a 'burn in', and some say that its totally BS.
What say you?

I have a feeling that andy2 would disagree. He might say there are way too many of them.
no difference for breakin or direction.
variable AC exhibits skin effect and parrallel capactive coupling in all speaker wires proportional to frequency carried. 0-20khz is no problem.
only when you go a few 100khz do standing and reflected waves impact a

While resistivity of a wire can impede the flow of current and make heat, the inductance of a wire/transmission line can also impede the flow of current but this impedance does not create heat since the energy is ’lost’ in creating a magnetic field rather than exciting electrons in the material. This impedance is called Reactive impedance in AC Circuits. We used the word ’lost’ however the power is not truly lost, it is used to create the magnetic field and it returns when the magnetic field collapses.

2.) Skin Effect:
In AC power electrons like to flow on the outside of a wire. This is because the changing of current back and forth causes eddy currents that result in current crowding toward the surface.

Skin Depth

Skin depth is a fixed number for given frequency, resistivity and permittivity. The higher the frequency of AC power in system, the more current is compressed on the outside of the wire, so a wire that is used at 60 Hz at a given voltage will not be ok at 200 MHz. Engineers must always have the skin effect in mind when designing circuits. See the wikipedia site for the formula used to calculate the skin depth.
Above: engineers overcome skin effect by by using insulated stranded wire. If you make the individual strands equal to one skin depth, most of the current flows in the entire cross section and you use all of the copper. The downside is your wire must have a larger diameter as you need all the extra space for insulation. As the wire strands get smaller in diameter, and the insulation stays the same thickness, the ration of copper area to insulation can become less than one, then you will have more insulation than copper in the winding or cable.

 current traveling on the outside of each strand. This gives more surface area as a whole and allows for a large amount of current to travel through.

I have nothing against lawyers.  Only the ones I know of.

So I am not the only one to doubt Einstein as the biggest science star that we made him into?

Don't put words in my mouth. I think Einstein deserves to be the big science super star ⭐️ he is simply for turning Newtonian physics on its head. He gets a pass on any mistakes he might have made.
