The thread below about the distortion in iTunes brought up an old question I always wanted to ask but never did.

What's the purpose of the preset equalizer setting in iTunes? Don't you think the recording studios use much better equipment and have already applied the correct equalizer curve for each CD?

Are you saying that each recording studio should come to my hours/car/boat and set up my equipment to match theirs?
COOL!!
