I haven't looked at the cap figures, though, and it may be that Mogami is much higher.
I haven't either -- but capacitance is an obvious first port of call. There are numerous other factors that affect cable 'sound' though, including the nature and diameter of the dialectrics between the core and screens. And then there is the issue of RFI and how the cable deals with that... and how the equipment it is connected to deals with it.
There is so much RF flying around these days, and a surprising amount of equipment really doesn't deal with it very well. I am quite convinced that this plays a big part in the impresion that different cables sound different -- even over short lengths (which could suffer RFI issues even if the capacitance/dielectric issues can be discounted).
However, gaining access to a suitable faraday cage to test the hypothesis isn't easy...
