How do you know which is 'better' though. The bi-wire or the single

I'm aware of that. I was assuming that, if there is a change, then it's a
change which brings a technical improvement, in the same way that having
lower resistance cables brings an improvement in technical terms.

There is a very definite interaction between speaker impedance ( which varies
over the audio band ) and cable resistance that affects the frequency response.
The effect is quite small but readily measurable.

The effect is *always* reduced ( i.e. made better ) by using a larger gauge of
wire. The effect of bi-wiring in comparison isn't so straightforward but will
always be inferior to using those same 2 wires in parallel.
