Why do you think Bi-Wiring improves the sound ?

Bi-wire is great but sonically by amping with the right amps is always better.

Considering that the feedback changes the effect of this resistor and makes it approach 0 ....

Hint, is the emitter resistor in the feedback or not?

Irrelevant in the models which show that changing 1 parameter affects response.

Historically this was never provided for bi-wiring, it was provided for Bi-Amping to reduce IM distortion and/or tailor amps to frequency range.

Some consumers (and importantly also reviewers) seem to believe that it does, and prefer to buy loudspeakers which provide this option. Some manufacturers may therefore feel compelled to provide this option due entirely to these marketing pressures and little else.

Hmm, nobody took a note of the posted link in this thread. That explains why bi-wire works and the science behind it. With measurements, graphs and all.
Rather clever test track and method they have composed to use to be able to measure and show the effect of Intermodulation in a same cables single (wires) configuration and in bi-wire configuration. 

It is making a scientific proven difference but if it is detected by ear or not. That are determined by several OTHER factors. So audiophiles that are able to hear the benefits have some of the other factors aligned (room, speakers, gear and so on).


Used test method:

Notes

The test tone CD was played using an all in one CD player/amplifier set at half volume into a pair of floor-standing speakers. The current probe measurements were analysed using TrueRTA via a Tascam US144 USB audio interface. The single wired measurements were taken with two runs of speaker cable wired in parallel (speaker shorting pieces in place) and the bi-wired measurements were taken using the same arrangement with the shorting pieces removed. In this way both measurements used the same cross-sectional area of cable to eliminate any effect of lower resistance on our measurements.

I will paste the link again for this thread so it is easier to find than go back and try to figure out which one it is:

There is a couple of analogies that are used in the explanation. That is needed for me anyway to be able to grasp the complex working of it. That may need to be re read and let sink in.

So we see that there is much more than some false logic that will cloud our thinking and make the individual more comfortable to put for example this specific effect aside. When it is not properly understood or known.
