Do speaker cables need a burn in period?

@geoffkait 

Here you go again, changing the subject without providing ANY proof of your statements?   We are ALL waiting for your explanation on how wire directionality works in a AC circuit???

Come on, step up and share with us your vast scientific knowledge!

Engineering fact and law reverts to Scientific theory.. in the moment you have unknowns and are in the act of exploring.

Laws and facts are for punishing the outlier for being different than the clan.
It’s all theory in the given exploration... as the record is subject to change in the face of said exploration.

If it’s all facts and laws then the future will be exactly the same as the past. Science guides gently with aim and direction, it does not force and exhibit tyranny and dictatorial rule, like the laws and facts of engineering. If it does (exhibit forced prior conditionals)...it means no one will be alive or change or grow and we’ll all be mindless dead automatons. Humanity as a corralled and controlled commodity.

Is that what you are looking for?

Importantly... the very heart of science, what it is, how it works, what embodies it’s very meaning and flow --- is the outlier.

No outliers.... no science, no change, no life. All you’d be left with.... is a boxed dead commodity.


I think you misunderstand how science works.

@teo_audio  Well, if that were the case i would had trouble staying employed for the last 40 years.  

So reading your response you are trying to say that in some cases 
AC current does NOT behave in the way science & engineers understand it? 

Your statement sounds like the definition of Pseudoscience which consists of statements, beliefs, or practices that are claimed to be both scientific and factual, but are incompatible with the scientific method.

Az, it’s OK that you were lying about being an engineer. I totally understand why you would do that.  You must be the oldest Subway employee on the planet.

I can see the argument for "directionality" if the condition is not symmetric.
Let's say if one end of the cable is subjected to one condition, and the other
end is subjected to different condition, then it's possible that the cable
could be conditioned differently if you reverse the direction. For example,
if one end is constantly biased to one voltage, and another end is biased
to another voltage, then there is a possibility that the argument for "direction" has some merrits. No if the current is DC then of course you have directionality, no question about it. But music signal is AC so that is the tricky part to argue if you are the proponent of "directionality".
But if the current is truely AC, then the current is always symmetric.
But is the currrent always AC? Could there be a small DC offset current?

For example, you have an amp driving a speaker, one terminal of the cable is being biased by the amp output transistors and the other terminal of the cable is connected to the speakers. If the output transistors are DC coupled, then you have a servo on the amp output to adjust for the DC offset, but this servo circuit does have a small (maybe even very small)DC offset so there will be  a small net DC current flowing from the amp to the speaker. So in this case,  it's not symmetric and the "directionality" argument might make sense.

In the case of interconnect, you have a preamp driving the amp input. In
this case, DC offset is not as important because you don't have anything
driving the speakers. I am not a preamp or amp designer so I don't know
how the detail of the preamp output design or the amp input design, but
there is a strong possibility that the interconnect terminals on both ends
are not being subjected to the same condition, so therefore there is an
argument for "directionality" even if the current is always AC (for example
the preamp output is capacitively "coupled" to the cable but the amp
input is biased to some voltage). So in this case, you have a symmetric
AC current, but non-symmetric bias condition on the terminals of the interconnect.

For the proponents of "directionality", the difficult part is that you have to
make a case how a symmetric AC current has anything to do with "directionality".

For the opponent of "directionality", you have to explain how different
bias condition on the terminals of the cable does not affect the cable
if you reverse the cable direction.

I am not a proponent or opponent of "directionality" but I present some
possibilities for the "directionality" argument.
