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.

If the audio chain consisted of one box connected to the master feed via lossless transfer on the input and your brain connected directly to the output via cyber/lossless transfer then perhaps you would have a bit of a point.  As it is, everything matters and does alter the sound to varying degrees on all equipment.

If “Everything matters and does alter the sound to varying degrees” wasnt such a gross generalization you might have a bit of a point.


Sure Shadorne, so happy you are fortunate enough to have gear that you just plop down and enjoy without a care in the world!  Sometimes a judicious amount of ignorance goes a long way to happiness:). Enjoy
+1, @dave_b.

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!
