Far be it for me to side with everyone else.

Some people find no physical basis for it, others do. Some use simple
electrical engineering explanations for what appears to be a complex
process, especially given the sophisticated hearing/interpretation
mechanisms that humans have. Some use what appears to be fantasy to
explain how it works.

The fact of the matter is that electrical conduction in a wire is
pretty straightforward and well understood at audio frequencies..
Hearing and room acoustics are certainly more complex but that has
nothing to do with typical good-quality speaker cables.


Most scientists I know talk in terms of 'suggests', 'indicates', and
'theory', rather than black and white certainties, and this makes me
want to try many things for myself.


Physicists create theories to describe the real world and correct them
when measurements indicate that the results are not compatible with
careful unbiased measurements. Electrical engineers create models
based on physical theories and change the models if they are not
compatible with careful unbiased measurements. However, you would be
hard pressed to find any significant issues regarding modern
electrical theory or related shortcomings with respect to speaker
cables. You are certainly free to propose modifications to existing
electrical theory with respect to speaker cables but to have
credibility you will need careful unbiased measurements.


the problem is, there are no careful, unbiased measurements, because there is
nothing to measure. The things that affect an AC signal traveling over a
distance on wi overall DC resistance, capacitive reactance, inductive
reactance (which are components of impedance), are simply not significant at
audio frequencies. Speaker runs would have to be hundreds of feet before any
of these had even the slightest effect on an audio signal and even then, it
would be merely a slight attenuation of the very highest frequencies.
