Well, here i am a year later. Picked up the 2001 release recently and i'm very pleased with it. Still not perfect though. I've noticed a couple of subtle wobbly warbles. Most of them are on the first 5 seconds or so of tracks, which would indicate master tape problems perhaps, that cannot be rectified anymore. Some i've noticed are :

16 : The fremen (5 seconds in,it wobbles very briefly)
21 : Reunion with Gurney (6/7 seconds it wobbles briefly)
13 : First Attack (I simply cannot tell with this track. To me,it sounds like it is dragging in places like a heat warped tape. Again, it may just be the actual style. Maybe just a warbly sound to it. In my opinion, there is "some" warp effect there. Anyway, it's a track i dont rate that highly anyway. There are other superb tracks)

But certainly none of the horrors that people speak of on this 1997 release. I'm glad i did'nt get that one.
