An Unusual Speaker Cable With Very Low in Inductance
« on: November 22, 2018, 10:23:45 PM »
An unusual speaker "cable" using parallel smaller wires, with minimum expensive.

My system sounded optimum using 10 parallel 18 gauge solid wires in each speaker "leg",
for five feet long. Your mileage will vary depending upon your amplifier output impedance (Z)
and speaker Z. I used door bell twin conductor wire (in a jacket) from ACE Hardware,
and only paid $.17/foot.

The inductance, resistance, and capacitance is extremely low. Nordost has designed
a similar cable except using flat conductors mounted on a plastic substrate. Cost is
much much higher if one wishes to use pure copper.

Caveat: The ten wires should not be tightly bundled touching each other, as the inductance will
increase. The other caveat is that the "+" and "-" speaker wires should be separated and inch or
two for minimum capacitance. (That is nearly always a good thing.)

Steve,
Are you using the same wire on your new icís?

The ic wires are 6N pure copper and stranded. The test speaker wires are just typical
solid doorbell wire from ACE hardware. Completely different wires.

Steve,
Just wondering....so does that mean that the purity of the copper wire is much more critical for icís (and maybe digital cables) rather than speaker cables?
Thanks,

The smaller the analog signal, the more critical the wire, plugs, and termination quality due to a smaller signal.
 
As a quick example for the public, say we have a musical signal from a turn table, 3 millivolts (0,003 volts). If we have garbage that is 30 uv (microvolts) in amplitude due to rectification effects, termination quality changes, noise etc.,
the 30 uv is only 40db down from 3 millivolts, and it is amplified like the musical signal. Even 3 uv is only 60db down
from 3 millivolts.

Now take a 20 volt signal, that 20 uv of garbage is 120 db down from 20 volts.

A 2 volt signal "in" an ic with 20 uv of garbage would be 100db down from 2 volts. The garbage could also
be much higher.

These are examples that could happen.
