Summary

Story summary

A blind test conducted by Michael, an audio engineer, on diyAudio.com showed listeners could not distinguish sound quality between copper cables and unconventional conductors such as volcanic mud and unripe bananas.
Despite significant differences in resistance, frequency response measurements were nearly identical.
The findings indicate conductor material does not significantly impact audio quality and challenge premium-cable pricing.
The online reaction included humorous responses from audiophiles.
