Hi all, I just purchased a set of low priced Logitech x-240 speakers + sub for my computer. I'm wondering what you guys think is the best volume level configuration to get the richest sound out of these speakers. I can adjust the volume directly on the speakers themselves, the volume in iTunes, and the volume in Windows. Is there a rule of thumb, like to turn one system down and the other up? I once heard turning the volume up in iTunes was the best idea because it is the first decoding point. What would you recommend?
