@Delroth: No, I'm afraid I don't have any programming skills. I'm much more an audio guy than a computer guy.
@tueidj: I assume what you're saying applies equally to both Gamecube and Wii. If that's the case, I did try recording from my Wii with Shiren the Wanderer, a game that uses 48 kHz SAD files for its BGM. The real Wii produces frequencies no higher than 18 kHz, the upper two kHz being analog distortion I assume. Anything higher than that is just random noise (which is still pretty visible on the spectogram; the Wii, or my Wii at least, has a noise floor of about -60 dB and then I had to boost the recording by almost 12 dB to get it to the same volume as the original file, so that's what all the blue fuzziness is above the music):

The real Wii recording and the original file sound minimally different, but the Dolphin LLE recompiler recording has a notable treble reduction. I can post my three files if anyone is interested. If you know what the rip from the disc sounds like, I've found this treble loss with Dolphin is pretty immediately noticeable on Kirby Air Ride especially. I can record with another game if you want, but I've seen the same thing happens with the Wii system menu music: clearly ~32 kHz on the real Wii, sound up to the Nyquist frequency with Dolphin.
Also, like haddockd mentioned before, I too get occasional faint pops/clicks. However, with Dolphin 3.5-322 the clicks are not present (I only know this because revision 247's audio in this game is screwed up pretty bad and 322 fixed it so I kept it around). If I did have any programming knowledge this would be just the kind of thing I'd commit a lot of time and effort to, but alas. For what it's worth, I'm willing to test out any patches anyone might attempt.
