Glad you "adire" me. - taking the simplified way.

Hi.

AA is not a scientific/technical institute. It's only a techno chit-chat space despite PHP being more technically oriented as many our readers want to learn yet not technically knowlegeable enough.

That's why I always take the simple way to try to provide easier comprehension for our less technical readers. This complicated subject is a good example whereby I employed the published data of insulation dielectrics commonly used to build wires & cables,in order to provide a simplified perspective how the cable sonics may be affected.

Of course, there are technically better or more thorough way to doing so which I never dispute. But I am NOT "incorrect" as you keep on pushing it. For AA readers, I believe my simplified way should be adequate.

We all know inductance, capacitance & resistance (L, C, & R) are the fundamental properties of any AC circuits, which surely include audio interconnects. But instead of putting these complex factors to make it more complicated for our readers, technically enough or not,
to understand the sonic issue of a wire or cable, I only use "half the physics" - skip them & use insulation dielectrics, which are also valid properties of a insulated wire or cable to give another view angle for our readers.

Mind you, you are pretty academic. You apply formaulae yet you don't seem to explain why & how you use them.

Let me go back to your assumption that a coaxial cable with theoretically vacuum as dielectric, will provide light speed transfer of the signal. I doubt very much despite whatever formaulae
you put forth to me.

You still fail to explain why & how these formaulae you suggested work to support your assumption.

Let me reiterate my point: a coax is by itself a capacitor, with its centre conductor as one pole & the outside shielding as the other pole of the cap when AC or DC pass through it. Its capacitance can be expressed as the formula I already stated in my past post.

Being a capacitor, it got complex impedance, with resistive, capacitive & inductive, variable at selected frequencies. Energy loss on the signal transfer is inevitable.

So how can the wave still travel at light speed as if it is a perfect zero-loss media even your assumption of vacuum dielectric stands.

This is only logics, I don't care what formulae you use.

PS: "capacity" in my quote means capacity of the wire or cable
is the overall capacity as used as used as a current carrier.
