I was buying a receiver and speakers in 2020 and when it came time to pick out speaker wire, the salesperson walked over to where the wire was and began the pitch...

Salesperson: so when the frequencies are higher the electrons end up traveling only on the outer layer of the wire instead of in the middle...

Me: yeah, skin effect, I did electrical engineering

Salesperson: ah, so I guess you know you don't need this then (pointing to gimmicky monster speaker cable that had a single strand of wire in a spiral around the main bundle with a clear jacket so you can see it)

Me: correct (grabs the cheapest 16awg)
