when I was on diyaudio.com years ago, there was a heated debate of "directional cables". so a bet was born: we made four cables, one with Romex wires (the kind of regular electricity wires you use to send electricity to sockets in your house), a Radioshock speaker wire (<$5 a pair), a non-directional high-end speaker wire (>$1000), and a directional high-end speaker wire. the pack was completely sealed so no one could tell what each was.
the package was sent to four diyaudio memebers who claimed to be able to tell cables apart, especially directional cables.
of the four, two openly admitted of not able to tell the cables apart, one admitted that he was guessing, and the last person took the cables and we never heard from him again.
over the long history of audio, there have been multiple challenges to cable makers to participate in a double blind listening test to show that their cables make a audible difference. so far, no cable manufacturer has participated, in spite of significant financial rewards if they win.
Bob Carver did a test in the 1980s (you can google "great amplifier challenge"), where he mimiced the sound of high-end amplifiers with his own designs, and no audio critics from two high-end audio journals could tell those amplifiers apart. |
