the comparison of results from the various cables that were tested. This is quite trivial of course, the characteristics, e.g. Z as function of frequency, are different from one cable to the next. But isn't that the very point, a straightfoward demonstration of the consequences of the varying cable characteristics with a fairly simple test setup?
A perfect cable wouldn't affect the signal in any way other than perhaps a prefectly resistive component that would attenuate all frequences equally.
The point I'm making is easily demonstrated by extending your example by introducing a second cable. Suppose it has 0.05 Ohms at 10 kHz, same as the first cable, but 0.2 Ohms at 30 kHz, twice as much as the first cable. Do the math and we get a different *net* result, trivial!
Now as to the question of whether it is correct to say that a cable "adds" distortion I really can't say but it seems to me that the question is basically pedantic if not purely semantic. The signal is distorted by both cables, and the way it is distorted by the first cable is different than the way it is distorted by the second... "distorts", "is distorted", "adds distortion" ... just another PH BS word dance it seems to me!
Everything matters, don't forget to tweak your placebos!
