Nsgarch, you are correct in saying that different frequency voltages changes travel at different speeds in different cable compositions, BUT, the differences are only apparent (even theoretically) at RF levels, i.e. a signal at 10 megahz might be delayed vis a vis a 1khz by some very small amount, but would be inaudible anyway.
Frequency variations and Phase problems due to capacitance and inductance are however more detectable at listening frequecies, but then, again, the difference in lengths of the same cable would have to be large indeed.
'Smearing' if there is such a thing, is not caused by the construction of the cable or materials used, but by the inherent electrical properties of the cable, IMO.
