But seriously, if you really don't have time to listen to your rig, get an iPod and listen during your workout. I have a friend who is a lifelong bodybuilder and previously he was a Jr. audiophile. He now has 3 busy children and a busy work life. He now listens to his iPod during workouts and has a couple of iPod dock systems spread throughout the house. I'll bet he doesn't listen to his big rig 1-2 hours a month now.
Enjoy,
