Supremus - Q. What are the benefits of bi-wiring using Supremus speaker cable?
Answer:
We have yet to introduce a bi-wire version of Supremus, but doubling up two
single wires would have the effect of doubling capacitance and halving
inductance and resistance. It won’t affect the dissipation factor,
because that is a unit-less ratio determined by the dielectric material,
which remains the same. This amount of extra capacitance will have no
effect on the sound, as the most important aspect of cable capacitance
is the dielectric material. Low loss dielectrics with low dissipation
factor tend to provide reduced capacitance, so this is why low
capacitance is thought to be important. Halving the resistance will be
the single largest improvement because it brings the speaker terminals
electrically twice as close to the amplifier, reducing the affect of non
linear-loss across the cable. Reduced inductance can only result in
better transient performance and reduced distortion. You can find out
more about this in the attached Supremus report:
