In a blind test, audiophiles couldn't tell the difference between audio signals sent through copper wire, a banana, or wet mud — 'The mud should sound perfectly awful, but it doesn't,' notes the experiment creator

A blind test conducted by a moderator on diyAudio revealed that listeners struggled to differentiate between audio signals transmitted through copper wire, a banana, or wet mud. Results showed that participants could not reliably identify which wiring setup was used for the audio tracks. The experiment aimed to test whether materials like bananas and mud, despite being poor conductors, could introduce noticeable changes to the audio signal. The findings suggested that listeners could not detect any significant alterations introduced by different materials, highlighting the surprising similarity in sound quality across various unconventional conductors.
