It's Simple


Cables have properties Inductance L, Resistance R and Capacitance C.
Ditto loudspeaker, connectors, electronics in and out. 

LRC are used to create filters aka Tone Controls.
Filters cause amplitude and phase changes.

Cascading LRC creates a very complex filter.

Another's opinion on a particular cable may not be valid unless they have a very similar system.

Stop it, that's just silly ....

Only the R (resistance) matters at audio frequencies (20 hz - 20 kHz). Thinner wire has more R - thicker wire has less R.  The L (inductance) and C (capacitance) of typical speaker wire are of too low a value to affect a music signal. Physics 101! The "golden ears" crowd will claim otherwise. Yet no one has been able to identity and prove the existence of Factor X . Which would account for the claimed difference in sound Q of wire A compared to wire B. All claimed differences are strictly ANECDOTAL!
