The principles of twisted pair, and coax are well researched, as guards against interference, so
preserving the media over the given length. These principles are well practiced by every cable manufacturer.
What we see from this when applied to audio systems is a cable with characteristic impedance, but partnering
equipment not satisfying that impedance, and for good reason, as audio systems are generally not regarded as transmission lines.
Suggested by Cyril Bateman applying to amp speaker cable relationship is an insight that reflections do occur
at the upper limits of our perception.

and the upper limit of our hearing is researched by David Blackmer

So on one hand we borrow a attribute of transmission lines to guard against interference, but the asset of transmission lines applying
at audio frequencies to interconnects, just does not apply.
What is interesting though is applying Zobel networks as Bateman suggests.
