If you actually do the calculations to determine the "characteristic
impedance" of a transmission line in the audio frequency range, you
might be more than a little surprised. The line doesn't have one; it is
frequency dependent, unlike the situation at "RF".

That's because audio frequencies have very long wavelengths.

Only when the cable length approaches the signal wavelength does a
characteristic
impedance become a relevant issue.


Has anybody done an appropriate ABX double-blind test on the effect of
hi-zoop speaker cables on lamps ?

Do the words spring out of one's book with more depth, is the room bright,
less glary ? Is the spectral balance more even (none of those stressful
ultra-violet undertones ) ????
