This is a great album, obviously, but I have a few things to add about the mastering. I've read all the reviews of the Sanctuary import version, and a lot of the same problems are here, as well. The first four tracks are fully remastered on this Shout! version, but the entire Karn Evil 9 suite sounds like it was taken directly from vinyl! I can hear all the same imperfections I remember hearing on vinyl growing up. It sounds like they used the wrong tapes for Karn Evil 9, because that suite is NOT remastered. The difference is very obvious!!!
