There are many different ways and contexts and purposes listening to music, it has many different roles - but none make me "doubt" my system...
Concentration
I believe to get the best experience with your stereo you have to give your full attention to the music (not the sound.) Reading, doing chores, or writing something (like I’m doing right now) really lessens your enjoyment and can potentially cause you to doubt the quality of your system.
