When you say "cover"...are you referring to the album jacket? If the jacket is all white (no graphics), then you may have purchased a test pressing. Ideally...that's a good thing. It may have been a pressing made before the thousands of copies were pressed (for internal MFSL use). If that's the case it *should* technically sound better...assuming they didn't listen to the pressing, think it sucked, and decide to completely remaster the album and re-press it. :-)
