Actually, transmission line performance can vary greatly with conductor
resistance.  At low frequencies, (low is relative to the transmission
line) most of the conduction is bulk instead of surface, but concuctor
resistance still matters.  The resistance of the conductor affects
such things as signal degradation and propagation velocity, which will
in turn affect dispersion.  Admittedly, between DC and 20 kHz, there is
little difference, but some audiophiles will claim to be able to
hear it.  If there is interest, or I have time, I'll work through
the equations and post results.
