^^ well the BEST option is to use DFX (these are amplifying s/ware of 3M<B to 4MB in size, really small for a d/load) that can be used with many Media players like Winamp, Div X, Windows Media player, Jukebox, Jriver etc etc....
And, i can bet that these DFX plugins DO make a HELL of a difference to ur audio listening experience.. jus google it..
Cheers n e-peace....
