Oh, I just looked up the specs of the capacitance range on a cheap
AN8008 multimeter I have - On the 9.999nF range the resolution of
0.001nF, 5% +/-20 counts. That should be able to measure around what you
need, assuming cables are within the ~100pF/m range.
You are more than welcome to borrow that if you want, or pop over and
try to measure a few cables.
Can try it tonight and report back...

To do this he wants to make a comparison of the electrical properties of different brands of audio cables. His hypothesis is that there is no difference between 'audiophile' cables vs cheapies.
