Actually my Q1 is related to Q2. In Q1, since dielectrics are said to be not perfectly linear and can distort the signal (eventually sound I assume), I don’t know if the thickness of the dielectrics play a part in the degree of this nonlinearity (or sound distortion)?Yes, it plays a part in how much the nonlinearity can affect the signal. The thinner the dielectric, the less effect any nonlinear polarization of the dielectric can have on the signal.
In the A2, it seems that because of increased (due to thinner dielectric) or decreased (thicker dielectric) capacitance, it brings different degree of distortion.
But the volume of the dielectric diminishes to a degree greater than the electric field increases which means that unless there is some highly unusual distortion behavior, the thinner dielectric will result in less distortion of the signal.
How about the thickness if the same dielectric is used for both the cables (thicker dielectric & thinner dielectric)?
That would be even more advantageous than a better but thicker insulation versus a worse but thinner dielectric.
In my last post, comparing Teflon to Teflon for both the thick and thin dielectric, the thick Teflon increased capacitance by a factor of 1.85 times what it would be with no dielectric and the thin Teflon increased capacitance by a factor of 1.25 times what it would be with no dielectric.
(p.s. sorry for the not-so-well organised questions)
No problem. We'll get it sorted out. :)

[ But the volume of the dielectric diminishes to a degree greater than the electric field increases which means that unless there is some highly unusual distortion behavior, the thinner dielectric will result in less distortion of the signal. ]We don't know for sure about that last part, at least in the other posts, you were careful to point this out. Let's not let this become a 'fact' by mere repetition.

What is it, Jon? Did you only read the first and last part of the sentence and skip over the middle portion or is it a vocabulary problem?
What does the word "unless" mean to you?

You mean like loudspeaker manufacturers routinely smoothing their impedance plots in order to hide severe resonant peaks?
