The Physics of Electricity


Can anyone explain clearly in either common parlance or technical terms the difference between a $1,000.00 cable and/or speaker wire versus a $20.00 (or so) one? What does wire "do" in an expensive cable/wire that an inexpensive cable/wire does not? Does it conduct more or "better" electricity?

"takers"?

Sure, what do I get?....and it has to come with real whipped cream...none of that edible oil product in a spray bomb eh....and maybe one of those fancy cherries on top would be nice.
OK admittedly not my best work but I've had a hard week and given the circumstances that is all I can muster right now. 

So stop being such a tease and just float me one till, say, Thursday....and you can hold the cherry but the whipped creme would be nice.
Given how that the term determined is used, as in...

determined by the dielectric or insulation material

...and the definition of determined as used implies...

ascertain or establish exactly, typically as a result of research or calculation


Mr Geoff has a point....and a good one....not to say there isn't some affect, which there is, but definitely not ascertained or established exactly....or wholly.

Just sayin’ eh.
But wouldn’t that nano-tech surface treatment require exactly the same electrical parameters as the base carrier to work well ? Otherwise something as elementary as an impedance mismatch would produce reflections that could really complicate an already complisticated situation.

So the idea is have a conductor surface as smooth as a still pond at nightfall that could, say, yield a staggeringly good reflection and not a jumbled chaotic mess akin to noise ....fascinating stuff indeed. The potential if that could be achieved is simply bogglistical eh.
...technology that optimally aligns the crystals while reducing the number of crystal-grain boundaries resulting in a tremendously efficient conductor.


Straight OCC’s benefits are its larger “fibrous” crystals in which one dimension is longer than the other two so as to create as few crystal junctions as possible.


Gee, someone with a lot of solid engineering expertise went through a lot of high priced trouble to reduce the effect of crystal-grain boundaries. So if more is better, or in this case, less is better, would be kinda interesting to speculate what kind of benefit could occur if there were no "crystals" or "crystal junctions" at all eh. But that is the stuff of science fiction ain’t it, though it would make for a very fascinating thought experiment.
We have enabled listeners all over the world to get closer to their favorite music by making it sound as crystal-clear as possible.


Don’t want to seem like I’m nit-picking or anything but wouldn’t simply clear be mo bettah than crystal-clear....like just cut out the middle man ditch the crystal and go directly to clear. Kinda makes sense eh, or am I missing something ?

And then there are the phase shift issues that are at the heart of the manner in which damping functions. Jeez they could gone whole hog on the ultimate and simply invented a mechanical diode or something that has no phase shift ( cause that is the ultimate ...no out of phase decay... )....and fixed it real good. And yeah a mechanical diode is apparently impossible but we are just dreaming and being a bit silly here, aren’t we ?
Well, it depends who you ask. If you look up Dr Wiki he says the following....which given the currency that defines Dr Wiki's world is pretty well just the bog standard interpretation ( which mostly seem to be variations of you're messing with my magnetic field dude..).

https://en.wikipedia.org/wiki/Microphonics

But if one were to present that to the experts in certain patent offices they will say that the effect doesn't exist and all talk about it is just plain hooey.

So pray tell, what are your views on the subject ?
Sorry but a bit more confused than normal....the original post spoke of external vibrations not vibrations in cables.

So maybe defining the terms more strictly might be good eh.
