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.

However a system’s degree of fidelity can be quantified in how faithful it is to the actual recording it is presented
Who's on first? 

The instant the sound wave hits the microphone diaphragm, absolute HiFidelity is gone.

Alan Turing [of The Imitation Game] devised a test for computers: the machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human.

There isn't a studio in the world where the sound is the same on both sides of the glass. By the time it gets to the consumer, it is all Lo-Fi by Turing Test standards.

The true test of any playback system is does it involve the listener in the music of their choosing. That is all that matters. Arguing about relative merits with the ill-educated is pointless.

I was a recording and electronic design engineer and invented the Vocal Splicer. I quit recording in the late 80's with the rise of drum machines and computers. I had a business installing recording studios and manufacturing electronics for the recording industry. We also modified recording electronics. Later I worked for a recording console manufacture as head of Analog R&D.

I'm pretty certain that a great many audiophile products could be shown to have no or even negative effects in terms of absolute amplitude and phase coherence. Those that do affect phase and amplitude may improve some systems, have no effect in others and be down right negative in still others. It astounds me that there is so little proof and so much hyperbole.

As far as understanding LRC and "minimize any artefact from bits of wire", yes I understand LRC. And yes, it is possible to design to minimize wire effects. However, that may be counter productive. If I design an amplifier or loudspeaker that sounds better and better with every better and better designed cable, I'd say mission accomplished. An amplifier or loudspeaker that showed no improvement with better cable, I'd class as mediocre. When I say better cables I mean better in terms of design to maintain phase and amplitude so that the signal is the same on both ends with a wide range of driver and load topologies.

You clearly didn’t read what I said. I said faithful to the recorded music and NOT to the singers voice or sound BEFORE it reaches the studio microphone and is modified by said microphone. Nobody but nobody expects recorded music to reproduce the live event perfectly.

Sorry but you aren’t making any sense and your reading comprehension is poor. An appropriate plain cable or wire is not going to change amplitude or phase in any meaningful way. You have lost all credibility despite an appeal to your expertise as a designer.

”Involving the listener” is a meaningless concept and a bunch of hand waving - it can’t be measured and it most certainly isn’t high fidelity or faithfulness to the recording.
