Why do you think Bi-Wiring improves the sound ?

Let's face no one knows why bi-wiring improves sound quality. Not one single credible explanation offered so far. 

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.

On the other hand many believe it doesn't - including those manufacturers who on principle don't even feel it relevant enough to allow their users the opportunity to try it out.

Some might even be of the opinion that bi-wiring actually makes the sound worse.

Cable manufacturers and dealers on the other hand....

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

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

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 ....

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.
