Are cables BS?

"It is truly sad that audiophiles seem to be 100% lost on shielding. And I mean LOST. First big thing, audio signals both speaker and interconnect are LOW FREQUENCY mostly MAGNETIC property signals. Not ELECTRIC fields. Sure, ALL electromagnetic waves are “both” B and E fields but the vector magnitudes of the two fields differ, and substantially. And, this ALTERS how they interact/cancel. Our best friend at audio is to know that B-field magnetic waves decay at a ratio of 1/x^3. So MOVE your cables apart, and especially cables with large CURRENTS (speaker cables) that will have magnetic properties extending well outside the cable. The interconnect have the SAME FREQUENCIES but far less CURRENT so the fields are far, far smaller…but they are STILL magnetic in nature! What about all the FOILS and BRAIDS on interconnect cables? These are for ELECTRIC fields such as EMI and RFI well above 1 MHz. YES, ONE MEGAHERTZ. Audio cables better have near ZERO EMI/RFI to be shielded from EGRESS (inside the cable to outside) and ONLY need ingress (outside the cable in) for terrestrial EMI/RFI. Better yet, the input needs a low pass filter to ground above 1 MHz. Digital cables CAN spew EMI / RFI so shields are needed. But were talking AUDIO for right now. Speaker cable aren’t shielded because they are a “different” kind of signals. They are the same 20-20KHz magnetic field vectors as interconnect cable. The speaker cable signal is just far, far stronger GAUSS density relative to any terrestrial EMI/RFI NOISE. Low impedance speaker cables swamp out the interconnects radiated magnetic fields and ignore EMI/RFI pathetic B-fields for the same reason. The magnetic in nature signal is too big to be bothered by them. DISTANCE or low permeability metals (stuff a magnetic sticks to) is needed for B-fields. A faraday cage is an example where it routes magnetic fields AROUND what is INSIDE as the cage is a lower permeable path to magnetic flux lines than the air is. We could stick cables into magnetic conduit, too. This will route the flux lines around what is inside the conduit. It has to be stuff magnets stick too, not what is called electricals conduit that is more a fire block or E-fields short to ground. Going up and up in frequency, we now need to TRANSITION to a material that is a low permeability to ELECTRIC fields, or is CONDUCTIVE to “E”lectricity. This is braids and foils, typically. And yes, the metallic conduit we use, too."
