I speculate this is due to both low capacitance, and reduced skin
effect.

Unfortunately, these were very expensive cables. Do any reasonable
cables
have similar characteristics?


Inductive & capacitive effect of speaker cable (in uncoiled, reasonable
lengths anyway) at audio frequencies is just about zero.

Mick,
What is the skin depth for copper, at 10 kHz ?
What is the depth for the current density to drop by a factor of 0.7?
