From the article:
Do cables affect frequency response? Yes. That too is visible and measurable. In particular, the Shunyata deviates in a positive way. And this cable does so in all cases. Your author believes that it has been proven that a cable has an influence. In our tests it is about values of sometimes 0.5 dBu. That is audible. Is it worth a serious investment? We’ll leave that up to you.
the differences will be notably more huge, if one does transient and complex transients stacked and their harmonics, as a fundamental test.
As LITERALLY, that is how the ear hears and works. the other 90% of the signal used in the test, is meaningless, as the ear never uses and never hears it.
This is about how engineering and tests relates directly to how we hear. So get it right.
