Audiophile nonsense is one of those hard-to-parody things, like religious fundamentalism: Poe's Law states that no straight-faced parody of fundamentalism can reliably be distinguished from the stuff real fundamentalists actually say.
(For comparison, consider ILikeJam's page of real audiophile products.)
Nobody's dying young because of audiophile flim-flam (well, not unless they leave their amplifier plugged in while they replace the tubes...), nobody's spending money they can ill afford to lose (well, OK, maybe some of the crazier ones), nobody's being led into criminal activity. Audiophile nuttitude is just people getting together to fool each other and themselves. Sometimes a lot of money changes hands, but it's all entirely voluntary and essentially harmless.
