I have installed product, restarted twice, and it does nothing to the audio in iTunes as the below reviewer stated. Not only do the presets not affect iTunes audio, they also do not move the sliders in the application, and even manually moving the sliders does nothing. After problems resulting from the OSS 3D plugin forced me to remove it in iTunes 6 i was hoping this major update would allow me to start using it again, but it looks like i'm back to being sorely disappointed
