How does cable construction affect sonic character?

As someone said, it's a religion. It can't be proven but believers have faith. 

Interesting video. 

A good sommelier can determine by taste which particular area a wine comes from, which grape, even which particular vineyard and which year. It comes from experience and his/her hyper-sensitive taste buds and smell. Can a laboratory instrument capable of chemical measurements do the same? I doubt it.

I think our listening skills are like that. Some of us are more sensitive to sounds than others. I think listening over a long period of time, and listening to lots of different systems and components brings experience to be able to discern like a good sommelier does. Once you have it, it’s very easy to hear very subtle differences.

Its only miraculous if you deny that an application of well understood mathmatical principles is responsible for achieving what believers applaud.

This is possibly not something those who have been reading audio reviews (perhaps for decades) have been taught to believe.

Cable construction, specifically spacing between connectors, can affect the capacitance and inductance, which, if large enough, have measurable effects on frequency response at the speaker. The science guys do not say all cables sound the same. They say that cables that measure the same sound the same.  “Cable believers” as many refer to them, believe that cables that measure the same can sound different. Take your choice. It’s your money and ears.
