well they did remaster some old tracks for the 1992-2002 anthology.
I also think STITI sounds quite good, although a bit quiet and a bit noisy in places. I also noticed when looking in an audio editor that strangely the left channel seems to be quite a bit louder and more limited than the right. Check out the wave of Confusion the Waitress on the lower left:

BF was a lot more "in your face" and quite loud. For OWB on the other hand they seem to have really tried to keep the dynamics and even on the dance tracks there's none of the usual "square block of sound" if you look at the waveforms (see Crocodile top right)
