I searched far longer than I should have for that web page where the guy tricked all the audiophiles with his cheap cables. No luck. However, I came across a great, in-depth article from a guy who made speaker cables from coat hangers and tricked a bunch of audiophiles… but included the science to back it up. A great read if you’re a gear nerd, like myself:

Are audiophiles treated poorly in prison? Are they segregated for their own safety? Perhaps they should be! 🤪
