The one Jetrell Fo so kindly reseeded is the raw wav extract of the DTS discs. Exactly what I was looking for.

As for the quality of the mixes, the 97 mix is just the good old OOT 93 mix with additions (but the added benefit of being in the original separate channels for full 5 channel surround sound). The 2001 version is remixed from the original elements. That particular edit sounds deliberate to me with the first line being lower than in previous mixes. I will have to check out the quality part when I can listen to it with headphones.
