What a great show off of "off topic". (long)

Hi.

First off, I already stated we cannot measure relevantly what we hear.

YOU still pursue this measurement issue. Yet you still fail to answer my counter question: "do YOU have the ability to measure it" -anything relevant to what we hear given your statement to me: "you may be unable to understand what or how to measure, that is your limitation, not mine".

Where is your answer as you already said you know how ??????

Failed to answer this your own issue, you diverted to something else not touched in my post instead - magnetic & electric fields.

What correct breakdown of what? I reiterate this is only an attempt of QUALITATIVE analysis based on wave progation velocity &
insulation dieelctric. You jumped in with your so called "half of the physics" - magnetic & electric fields.

Yet you failed to correlate how E & H affect or NOT affect the sonics of wires & cables. A totally moot diversion from the sonic issue.

Back to your moot argument on coaxial cable issue.
"The ONLY transmission line which has the ability to transfer a signal at the FREE SPACE velocity of the dielectric is a coaxial line"

What is a "free space velocity of the dielectric"? Where can I find your back-up explanation "that if a coax is made with vacuum as the dielectric" in your above statement ????????
How can you expect anybody to understand what you meant w/o your
back-up explanation?

First off, a coax always comes with a dielectric. Your "IF a coax is made with vacuum" does not exist & your reasoning is moot.

I already stated clearly an ideal wire is a bare wire & there will be very little propagation delay in free air. In vacuum, the wave will travel in light speed along that wire. The idea is exactly the same as you justed posted.

However, your statement: "if a COAX is made with vacuum as the dielectric, the prop velocity of that coax will be the speed of light" is very questionable.

What is a coax? It comes with an overal surrounding shield ideally equi-distant to the centre conductor from all side. This is a capactor by itself due to its construction, regardless the dielectric is a realworld material or a theoretical vacuum as you suggested.

Its capacitance is given by the formula: c=7.36x(e) divided by Log10 D/d where e is the dielectric constant & D is the outside diameter of the coaxial cable (includes the shield) & d is the diameter of the centre conductor. Unit is pF/ft

With capactance involved, how can you expect light speed transfer of a signal along a coax even with theoretically vacuum as dielectric?

Then you diverted even out of wack on speaker cable vs speaker energy storage. What's that to do with ICs the original poster inquired?

Let me quote a statement from the published paper:
"The shape, diameter & spacing of the conductors and shields determine the capacity between them. Coaxial cables are a special application version of a single shielded conductor and may be treated in the SAME way."

I would not lightly dispute what is written in your textbooks. I only question how you apply it to the cable sonics we are talking about.

A bunch of formulae would not necesssarily help in situation like this where the original poster was seeking for simple answers.
