I'm not one to try on different speaker cables searching
for the right one, because there are math-based reasons
why this is futile.
However, a CD player contains so many different
components and varying circuits in both the digital and
analog sections, that it would be unreasonable to
suppose that there would NOT be differences in the
analog signal that comes out of them.
You have hit the nail squarely on the head. Double-blind
listening tests for cables merely confirm what physics
tells us MUST be the outcome of such tests. Therefore
both the math and the listening tests back each other up
by finding that that there is no reason why two
interconnects or two speaker cables SHOULD sound any
different, and the DBTs show that no differences exist.
The same thing applies to complex electronics.
In more complex active electronic components such as
amplifiers, preamps, DACs CD players, phono stages, etc.,
there is no electronic theory that predicts how these
devices should sound beyond a certain point (obviously an
amplifier of amplifier stage with 5% THD is going to
sound different from one which has less than 1%, and that
is predictable and demonstrable).
The reason why there is no *electronic theory* that predicts audibility is
because audibility is not based on electronics.
Audibility is based on the study of human beings and in some cases where
relevant, other mammals.
The study of audibility usually comes under a well-known area of scientific
study called Psychoacoustics. Note that this is hard science and not social
studies. The classic work in this field is Zwicker and Fastl's
"Psychoacoustics, Facts and Models", 1991, 1999. The models of audiblity
described in this work have translated into the development of perceptual
coders.
