I'll tell you what's written about the remastering in the CD booklets. I got all of the CDs with the box. Didn't buy them separately. Very little is said about years but here are the p (sound copyright sign) dates. Legend has written on it, p rermegacorp 1998, Unrest; 1999, In Praise Of Learning; 2000 and Western Culture; 2001. Desperate Straits says p rermegacorp 2004.
Legend (The Original Mix) - "for this reissue thanks to Steve Feigenbaum and Bill Sharp"
Unrest (Remastered) "remastered and prepared for this release by Matt Murman at SAE"
In Praise Of Learning (Original Mix) "remastered and prepared for this release by Matt Murman at SAE"
Western Culture (There is no information about this one in the sleeve so I assume that there were no poor remasters of it in the past or this is the first time it's been on CD.
Desperate Straits - "this reissue from the original tapes, carefully remastered by Bob Drake 2004"
I think these are the remasters/mixes to get. I know that Legend in particular had a dodgy mix on the previous CD (not released by RER) and I assume In Praise Of Learning did as well because it's the only other one that specifies original mix on the side of the CD case.
I've listened to them a lot and it seems as though Rer didn't succumb to the loudness war at all. You really have to turn your volume up on these CDs. It's fantastic, so dynamic.
Hope this helps
