Thanks for the reply. What was the "advantage" of high capacitive
cables?

In general, a cable which exhibits high capacitance will also exhibit
low inductance. Low inductance is *theoretically* desirable in a
speaker cable, as it reduces the cable reactance at high frequencies.
In practice, even driving a 3-ohm load over thirty feet of cable with
Naim NACA5 (probably the *highest* inductance cable commonly
available) will result in a treble droop of less than 1dB at 20kHz.

**Except that, with some speakers (notably electrostatics), low
inductance
cables may well be desirable. Here is the impedance curve of just such a
speaker:

In this situation, NAIM cables (unless the speaker is to used with a NAIM
amplifier) would be the very worst choice imaginable. Standard Figure 8
(Zip
cable) would be a slightly less worse choice. High power coax, or Goertz
MI-1 would be the best choices.

However, while that is *theoretically* true, even in this particularly
extreme case (and assuming the amplifier itself has no problem), I
would be surprised if there was any *audible* difference with the
usual 10-15 feet of cable.

**You DID mention 30 feet (let's get with the programme, Stewart: It's
almost 10 Metres, not 30 feet). My comments were couched, with that length
under consideration.
