Hi,

I've just put up a new webpage that provides some measurements on the
properties of a variety of loudspeaker cables. The page is at

http://www.audiomisc.co.uk/HFN/Cables3/TakeTheLead.html

It is an expanded version of the article published in 'Hi Fi News' a few
months ago.

Slainte,

Jim

No conclusions section there, but maybe as follows?

1. If you open circuit the cable at the loudspeaker end, it is better
if the cable is somewhat lossy, as this will prevent the quarter wave
Mod Z dropping to too low (potentially damaging) a value.

2. Provided you have a speaker on the far end, none of the cables
result in a particularly problematic load at RF. The minimum impedance
variations tend to come from the cables with lower characteristic
impedance (closest conductor spacing).

3. The Isolda behaves very differently to the rest, and provided it is
used as recommended, presents the most consistent and friendly load of
any.

I could do with some more info on the Isolda cable - what the inductor
is all about and how come the impedance drops so low without it.
