You FINALLY have everything just right & the first song you play(one you've heard a hundred times) sounds so bad that you spend several hours trying to track down the problem only to realize that horrible sound is an instrument in the recording that you've never heard before.
You know you're an audiophile if--
You just got a pair of speakers you can barely move yourself (inverse proportionality with age probably too)
The first house you bought cost less than your current stereo investment (ditto)
You have boxes of cables with which you don't know what to do
