I am attempting to rip my audio cd's so that they can be played from my hard drive. After ripping a particular track and playing the .wav using Win Media Player 9 and using the S/PDIF coaxial output from my ASUS p4p800s directly in to the digital input of my Marantz SR-7200 receiver, there is a distinct lack of quality (especially in the bottom end) compared to playing the same track directly from my Loewe Xemix dvd player using fibre optic. Given the fact that it is only a digital signal would it still be of better quality coming from say an Audigy 2 sound card which has digital outputs? Or is it there a better .wav player that I could use?
