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.

Wow another cable troll. Congrats on your first thread. Trolling sure is simple.

In the end it boils down to the choice of components. 

Are the components high fidelity or not?

Are the components designed to give accurate high fidelity that is independent of the cables used and their length or not?

A setup that sounds different with every slightly different piece of wire is obviously NOT high fidelity - the sound is all over the place and totally dependent on extraneous factors which can never be properly controlled or determined.
