Hi:
If the length of coax is less than about 1/10 of a wavelength then
you can approximate it with lumped elements, so the Zo is not that
important.
The impedance of coax is NOT a constant, so when used for audio you
need to look at more parameters than just the nominal impedance.

Some more thoughts on impedance.
?
I had a discussion with some EE
professors about coax cable, impedance, loss, loss due to the
"wrong impedance" and one suggested this article:
?
I doubted the claimed loss due to
mismatch, until I worked out the Telegraphers Equation for
myself.
