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.

IME, no component is perfect. Just like music, you put together a system based on personal preferences. You just need to make sure there is enough ‘synergy’ among the components to enjoy music cause that’s all it matters at the end of the day.

And cables do matter!
The varying degree can range down to 0. The less it matters, the fewer who should care. Some will care no matter what because individual perception itself is a HUGE factor always! Maybe the biggest!
