Please help.The difference in sound quality between WAV. and the original disc?

Hi i`ve recently ripped music into my media player with a brand new external cd drive wich rips at 48x.I have then burnt my tunes and performed a sound test,the original disc`s vocals sounded a little more louder where as the burnt disc`s vocals sounded a little less loud but all in all WAV. is the closiest format in sound quality to an original disc.But my question is that is there no way i could ever get a disc to sound like the original disc itself to the exact.I am a very critical listener but i`m very happy with WAV. but when i played it on big sound sytem with an output of 2310 watts it still sounds great but when i play the original disc i can still tell the diference even though it`s barely noticable.I distinguished the difference in the vocal sound by that the original does sound just that little bit louder.Am i being just too critical perhaps but i so badly want my music to be like an actual original.Is maybe because the sound technicians in the studio know all the right ways
