The problem with audiophiles is they have a propensity to believe the absurd. For example:

Clean power is, of course, important, but this is taking the proverbial. Any decent power supply should have proper regulation and ripple elimination on the DC output side anyway, so in high end equipment, these cannot possibly make any difference. Audiophiles will swear otherwise, of course, but a properly controlled double-blind test would almost certainly prove them wrong.
