High current power cables

@kijanki that is a good point. I am normally dealing on much smaller scales, so don't naturally think of these things. From a pure extracted parasitics view, spacing out the conductors will cause the inductance to go up which will soften power peaks. That may be beneficial for noise. Having an air dielectric will slightly reduce capacitance, but for a power cable, that would be a detriment. The claimed benefit appears to be around reduced dielectric absorption which would be an irrelevant parameter for a power cable, or speaker cable.  Back of envelope suggests it would be irrelevant for any cable in audio due to the comparatively low source or load impedances. It has criticality in some electronics, where very high impedances are used.

Now @clearthink , in another thread I said I was not an acoustics expert, which I am not, but I said my physics are above average. Significantly above average would be more correct.

Now I will ask kindly that you stop the drive by insults that are humorous, but also annoying and distracting to the thread.

I am quite certain I grasp the "facts" to a far greater degree than you, and if you would like to challenge your physics knowledge to mine, I am up for it. Formulas at 20 paces?

I want to ensure that members distinguish me and my posts from the condescending unhelpful posts of another member just above who has a handle rather similar to mine.

I think what has happened here is that I have what Americans call "hurt your feelings" but you need to learn, accept, and understand that "feelings" are not really the issue here if you want to converse in the language of science we use data, facts, and statistics to support a position a simple "that's not true" or "I know better" or "it's not supported" is not a proper, effective, meaningful or convincing response. 

I suggest, recommend, and encourage you to continue your Merit Badges and education and as I may have previously mentioned an internship might also be helpful to you.
