Snake Oil: A Short History
In audio, snake oil means fake science or fake technologyanything that's claimed to improve the sound of a system but that looks like an obvious rip-off. For some people, expensive speaker cables and interconnects are snake oil. A few objectivists consider AC power treatments snake oil: most modern audio components, after all, can correct for AC line-voltage flaws and reject "ripple" in a power supply's output. A handful of hard-core objectivists maintain that every new digital technology since the advent of the Compact Disc is snake oil.
