audiophiliosis
A disease of the mind resulting in one believing that the only good audio system is one that costs over US$20,000 and that stray magnetic fields in components through the audio path will distort the purity of the audio image righteously placed with loving care by holy Audio Engineers in the studio for your listening pleasure.
Man, my friend paid $175 for this stone that's supposed to clear up magnetic flux and improve sonic purity; he put it on his amplifier. Now it looks like a rock on his amp and I can't hear any difference when we listen to Megadeth. That dude has serious audiophiliosis.
