One thing not mentioned.... the source of the audio. What is the quality of the source audio. Are you using the best possible practices in converting audio to mp3? Are you using the best quality original source to convert to mp3????? Or is it an mp3 of an mp3 or a resample from who knows what.
You can have the best spec'd sound system in town but if you are pumping crap quality audio into it no amount of EQ, compression or black-box enhancer voodoo will really help, you can paint crap gold, but it's still crap.
