It’s quite simple. I am asserting that interference on speaker wire running from an amplifier to a passive speaker doesn’t matter. Saying otherwise was invented

It’s quite simple. I am asserting that interference on speaker wire running from an amplifier to a passive speaker doesn’t matter. Saying otherwise was invented by snake oil peddlers and you are doing harm with your akshually act.

RFI on a speaker wire going back to the amplifier is a big problem. As evidenced by all those sources. Buying more expensive cables isn't generally the cure and is snake oil. Indeed, shielding itself can add enough capacitive loading to actually reduce speaker high frequency response. But having to put in an RF choke on speaker wire to prevent RFI from having negative audible effects is common. And using a little bit of care to keep as much of the cables paired as possible, keeping runs as short as reasonably possible, and making reasonably good terminations is good insurance against it being a problem for you. I've given plenty of high quality evidence, while you've given a long video of someone making a measurement that is meaningless to what I'm asserting.

  You have provided no evidence someone can walk into a store and buy an amp, speakers, and speaker wire and suffer any problems due to RF interference.

    > You have provided no evidence someone can walk into a store and buy an amp, speakers, and speaker wire and suffer any problems due to RF interference. The ARRL wouldn't have to help neighbors of amateurs put chokes on speaker wires if this couldn't happen. Most of us have the experience of having a cellphone close to speaker wiring and hearing LOUD buzzes and clicks. It was a bigger problem in the AMPS days (with higher output power), and more often the interference gets into the amplifier by signal lines than it does by getting in through power lines and speaker wires, but it can certainly go in the output (or power) as well. Have you never experienced this? I still remember the first time I experienced this. I was 12, returning from a road trip with my (older) sister and her significant other's family, where we had handheld CBs. The hifi inside the house was demodulating and amplifying our CB signals; they could be clearly heard when we used the CB from the driveway. 5 meters of speaker cable was a good antenna for a 10 meter wavelength RF signal; a poorly filtered amplifier stage was demodulating and amplifying the signal.
