Why cables matter video by loudspeaker guru, Danny Richie

Spock said:
No. In my opinion it depends on the geometry of the cable and how the shield is apllied.
Paul (from PS Audio) says why (and from my experience his totally right)

Every cable should be shielded!

Sorry, have to disagree, cables are very much system/environment dependent, also curious why PSaudio are not using their own cables anymore if Paul knows how to make them.

That´s ok. We disagree.
But Paul is not the only one saying what he says about shielding.

Jorge Knirsch is a great brazilian audiophile, engineer, with lots of written texts about audio, especially on electric current and cables https://www.byknirsch.com.br/index.shtml

He says here https://www.byknirsch.com.br/artigos-12-06-audionews98.shtml

"...esta childagem deverá ficar afastada do cabo de tal modo a não alterar os próprios sinais transmitidos. Assim, em cabos digitais, como também em cabos de interconexão e em cabos de HDMI, a childagem é muito relevante, contanto que bem realizada."
 
So I wasted some time and watched the video. While Danny Richie did demonstrate that he some understanding (at an amateur level) of how an antenna works. He also demonstrated that he has little understanding of how AC cables, interconnects or speaker cables work.

Now it is possible for speaker cables to act as interference antennas. But it's rather rare. First you need an interference signal, than you need a speaker cable that's the correct length for that frequency interference and finally you need an amplifier that's susceptible to that frequency interference.

But he was correct that twisted or braided speaker cables are less susceptible to interference than spaced pairs like zip-cord.
