I just received this and I'm very impressed with the 5.1 multi-channel mix. It's totally immersive and very natural-sounding, with vocals in the front and instrumentals nicely distributed among all channels.  According to another reviewer, it's the same mix that was used on the 2001 DVD-audio disc, which is currently going for over $200. I can confirm that the copyright date listed on this disc is 2001, which would indicate that Warner did in fact use the same mix.
