The pic didn't show up. It doesn't matter though.

For speaker wires, the only things that matter are distributed R, L, C, and length.

The effective dielectric constant, characteristic impedance, and propagation velocity can be derived from the first 4.

It is trivial to duplicate any cable out there using off the shelf materials. How it looks is of no concern. (well, let's neglect the eye candy thing).

And very few engineers out there can appreciate or understand what is actually happening when a cable is connecting a very low impedance amplifier to a variable impedance load using a wire of impedance significantly higher than the nominal of the speaker.
