On the subject of reissue/remaster, I have found that the best reissue/remaster copies sound phenomenal when the right people did the mastering, and the pressing and vinyl quality are first rate. You have to research to find who did it and who pressed it. I have also been very disappointed with some reissues, particularly those that are sourced from digital files. The Pink Floyd reissues, on Pink Floyd Records, are fine examples of excellent mastering and pressing. Impex does a phenomenal job, I highly recommend the Jennifer Warnes latest reissue of Famous Blue Raincoat and produced by Impex. It's stunning! The list goes on, but I believe that you get the idea. Originals, as others have said, can be a crap shoot. Unfortunately that is indeed the case with originals, just as it is with reissue/remasters.
