I get a slight distorted sound on Media Player in a particular track, and various points, high notes, etc
I immediately play it on iTunes and dont notice any problem. I reppeated this a few times.
So you would probably say well then use iTunes. But I think the actual playback volume, in general, is louder in Media Player.
One other thing, its easy in iTunes to go to Visualizationa and Equalizer, theres buttons for them, but with Media Player I have to go to menus.
Your observations please, in case I missed something!
