An audio CD can be done in a way that your wav will not represent the full data on the disc. If you want an exact copy, you need to do a disc image with preserve empty space or something similar. The CD can contain both audio tracks and data tracks. Some audio tracks can be hidden from normal play and a ripper might miss those too. So if you really want to save an exact copy of the CD, you will have to find something better than wav to save the data. There are a few programs that can do an image to ISO format, that might be what you want. I guess it's a bit harder to find a player that can handle the audio tracks from an ISO though. (Memory is a bit vague on formats and names but this is the general idea.)
