1. Dust (of any kind - on any of my electronic equipment, namely computer and sound system)
3. When someone touches and moves any of my speakers... I have spent enough time with a ruler string to get my speakers EXACTLY where I want them for someone to just move them like that.
4. People who NEED to touch my drivers. Why must they even touch them? Does that make them feel complete? BAH!!
5. People who think I am wierd for listening to music in stereo when I have an "8.1" ch reciever (6.1 + 2xFront FX chans).
6. People who "adjust" my stereo... (need I say more?)
7. People who eat during a movie I play with my system (I don't mind if it's at their place - just not at mine.)
I have many, MANY more; but you all get the picture.
