I've been using it for a while with iTunes, and it's an amazing little plugin. It's pretty much just an equalizer but it works worlds better than ones built in with other media players. I wasn't expecting it to make that much of a difference but it really does. You jsut have to try it out to understand.

It's presets are well done, but I'm not sure if it's better than DFX (configured properly)....but at least it doesn't pop up the meter window every time I start it, it just starts minimized. +1
