Carbon fibre is quite resistive. Its conductivity is well below that of metals and this is causing rather worrying problems. Aircraft get struck by lightning not infrequently. The lightning attaches to the fuselage, passes through it and then leaves from some other pointy bit. The aluminium is a good enough conductor to handle the current. Maybe an antenna gets vapourised and a radio cops it, but they have duplicates. These currents would blast carbon fibre composites apart with the power dissipated. The latest composite aircraft need special metal lightning paths in order to be as safe as olde worlde aluminium ones.

Maybe they meant carbon nanotubes?

But, anyway, loss isn't really a problem with audio cabling of domestic lengths. Frequency response, distortion, time delay, power handling, bandwidth, dynamic range and any other objective parameters aren't problems either.

The 'problems' are described in terms of: 'air', 'soundstaging', 'pace', 'rhythm', 'granularity', 'openness', 'texture' and any number of indefinable characteristics. Education might be the answer, but as they say, you can lead a horse to water...

I've seen explanations where the mechanism is said to be the collection of unwanted radio signals. These thoughts have merit but miss the target by suggesting mystic cables as the solution. Anyone with RF pick up effects needs a properly designed amplifier, not wiring made from recycled bullets previously used to shoot werewolves.

A moving-coil pick up is one case where the effective source impedance is low enough to make the lower resistivity of silver attractive.
