Hi Jim,
The one thought I would offer is that the inductance of the particular speaker cable is likely to assume increased significance when used with an electrostatic speaker than when used with other kinds of speakers.
The reason is that the impedance of electrostatics typically descends to very low values in the upper treble region, specifically to 0.8 ohms at 20 kHz in the case of your speakers. And the impedance presented by the inductance of a cable will increase in direct proportion to frequency, and thereby become particularly significant in relation to that very low speaker impedance at high frequencies. The result being that if cable inductance is other than lowish upper octave extension will tend to be limited to a greater degree in the case of electrostatics, relative to what would occur if the same cable were used with a dynamic speaker, or with a non-electrostatic planar speaker such as the Magnepans. Especially if the length of the cable is longish, as the inductance of a given cable type will be directly proportional to length.
Of course, all of that says little or nothing about what kind of cable is likely to be subjectively preferable, as that will depend on many variables, including the output impedance and other characteristics of the amplifier that is being used, the sonic characteristics of the particular speaker as set up in the particular room, the recordings that are listened to, the upper frequency extension of the listener's hearing, listener preference, etc.
Best regards,
