At audio frequencies, you will *never* measure artifacts in cables
above -140dB referred to a 10 vrms signal, and usually much lower than
that, right at the -160dB or so limit of the measuring gear.
While there may be no _audio_ research going on in this area, there is
other continuing research on insulation properties at low
frequencies.
At very low voltages, with frequencies just above the
audio range, this is certainly active work.
Can you provide a little more detail on what research you are talking about?
There are also known effects at 60hz, which is in the audio
range.
Again, what effects are you talking about?
So, there are effects at very low voltages at reasonably low
frequencies and there are effects at higher voltages at audio
frequencies - I find it hard to simply assume that in the middle
of that curve there are absolutely no effects. I will certainly
grant that it might as easily not be the explanation for anything,
but there is reason to suspect...
What are those reasons?
As I started out, this may not be directly applicable, but there are
clear issues here that are not QED.
What are those clear issues that have to do with delivering audio
signals to speakers, or from one output to another input?
I think it is unwise to
characterize all of materials science as old/completed science.
Now you are making a straw man.
For speaker cables and interconnect cables, there is no new discovery,
or research to be done, in the last several decades, as far as I know.
I'm
willing to let the continuing efforts see if they show promise and
not just assume they won't.
