Audio quality and Vista

That is, should I simply rip a track from CD on each OS, save it as a .wav and use that for comparison purposes? Should I play a track in real-time from the CD and record it with an Open Source application, save it as a lossless .wav and use that for comparing 'fidelity' of the OSs, or ? I don't think ripping is the problem, as far as I could judge there are no indications that XP or Vista differs in this matter. If I understand correctly there are some flaws in XP design. This has a negative influence on sound quality (the Kmixer stuff). The audio part of Vista is redisiged and is supposed to be without the flaws of XP so the claim is that it sounds better. So this is about playing music on both OS. I don't think it will makes a difference if one uses a CD or a WAV as long as it is a uncompressed source, so we have the best possible quality input source. So the question is how to capture the output of both configurations in such a way that - it is certain that nothing but nothing in the sound system of both OS is bypassed - it can be distributed as a file - the capture method don't have an influence ont the result. In principe the signal right before it enters the soundcard is ideal (I2S?) but don't ask me how to do it or how to listen to it. An AD converter might be an option but then the quality of the soundcard will have an influence and also the quality of the AD-converter.
