Sorry, but I don't see the point in not using terminology correctly.
I was trying to be flexible on the “linear” terminology and avoid both confusion and debate at the same time, which I realise is next to impossible to conciliate.
When you say:

Impedance is only linear for d.c. Once you start to vary the voltage, you are in a "complex" world.
First, the impedance is not only linear but constant for DC. Second, your definition seems to say that complex does mean linear. I have many textbooks sitting on my shelves with chapter such as “linear circuit analysis”, “linear vibrations” etc. and they all involve complex numbers, amplitudes and phases. I’m not suggesting one definition should be held as absolute and do not care much about terminology, but if we use non-linear for complex, then what are we going to use to describe the true non-linear systems (material non-linearities etc...)?

Simplifying assumptions can be useful in generating understanding or analogy but I don't see the point here. Music is not sound at one frequency.
The point was really not to simplify the whole issue, but your post (#9) left me wondering if there was not something beyond my current understanding of what is measurable and I simply wanted to validate it. From our exchange I now see what you meant and can only agree.

The whole debate is due to people either over simplifying or rejecting good science rather than digging in and understanding all of the variables and how they interact.
Well said!

"Some" claim burn in helps cables sound better. Some says this is a joke. Maybe... to a degree it is plausible? And I say this only by relating it to this analogy:

You buy a new home... you walk in and look around and you see it's condition. As you live in it and months goes by it seems you notice some kind of flaw in the home as each day passes by, a chip in the paint or dent in the wall or squeeky door. After years of years with this home you see all of it's minor characteristics that you simply did not notice at first.

Could this not be the same with audio?... You demo a system and you hear it's sound but as you listen more and more to that same system every day you start to notice finer details, certain characteristics that defines its sound.

Could this be the same?
Catching up here... I like the analogy. According to its "logic," heating up the house hot enough and long long enough (burn-in) will make all of its flaws magically go away. Coool! Don't think any place I have ever lived has worked like that. Time and temperature always made the flaws get worse, not better. By what logic would we assume that the basic fuel for entropy would make anything - any cable - act more orderly? I can think of no analogy or logic or law or perspective or paradigm that illustrates or explains or supports such a view.
