David Salz of WireWorld demonstrated his Cable Polygraph at the Rocky Mountain AudioShow. Here are excerpts from the report:
He (David Salz) then proceeded to play paired comparisons of a direct connection vs. a particular cable, some of them from competitors. Even with the modest system and less than ideal listening conditions, the colorations imposed by each cable were immediately obvious. Although no cable is perfectly transparent, Wireworld’s cables, particularly their upper-end models, sounded quite close to the direct connection. Moreover, some of the non-Wireworld cables were revealed to be grossly colored.
Although veteran reviewer Robert Harley heard obvious colorations, the reader comments cable atheists were quite sharp: “…it’s hard to fathom how they’ve convinced themselves that an (albeit) very short bit of wire (call it what you will) and 2 RCA plugs isn’t an interconnect and that the wire used plus the connectors themselves have no net effect…”
Wow, now that’s a rebuttal to puzzle the experts – a cable denier saying the test is invalid because a very short wire surely has an effect. The remaining comments were also indicative that the readers were mentally distressed to think that cables have different sound.
