I haven't been a big Flaming Lips fan -- previously heard only Yoshimi -- but I picked up a copy of this album on release week and quite like it. I'll have to consider picking up Soft Bulletin on 5.1 DVD-A.
The sonics aren't as bad as Vapor Trails (for example), but I did notice the heavy compression and lack of dynamics. Clipping didn't seem to be too obvious, although I think I did notice some. Unfortunately, this seems to be yet another example of the poor mastering jobs that are now commonplace.
