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.

It depends on the meaning of “high fidelity”. I interprete that to mean “faithful to the source recording” which means that “more twitchy it can be to the subtlest changes in the audio chain” is NOT high fidelity but “highly finicky”.

I understand that “high fidelity” can mean different things to different folks - a highly euphonic (distorting) tube amp may be marketed as “high fidelity” when it is really adding a great sound of its own circuitry to the recording...far from faithful to the original but a sound that is nevertheless highly desirable to those who enjoy it.

One of the world’s top mastering engineers (Doug Sax) used his brothers proprietary tube designs to master countless pop and rock - giving it just that touch of tube warmth that made his services in highest demand for decades. A high fidelity setup will allow you to hear what the mastering engineer intended.
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
