i use real player now but the EQ is 3 band - very slack. i was thinking about winamp but have been unimpressed with it in the past. i mainly listen to music , but do watch some movies on occasion.

i use zune. zune, itunes, and windows media player are the only ones i have any experience with, but zune is definitely my favorite out of the three. my friend just recommended one to me, i can't remember the name but he loves it, it can play virtually any format of media thats out there. i'll have to ask him what it is and get back to you.

I haven't run into a media file that GOM Player can't play.  I'm not sure of the audio quality on it though.
