I bought this collector's edition set thinking that they were also remastered. They sound exactly like the CD I bought originally in 1993. The collection is nice, but it's unfortunate that they didn't go over and beyond to remaster the sound. I own their OK Computer Collector Edition as well and realized that all of these collector editions are not remastered. Radiohead has such beautiful sound and were not given the same treatment as the Beatles 2009 remaster albums. I won't be surprised to see these collector editions have another reissue with remaster sound.
