So many reasons to remaster with many not being worth the time to chase down but many are well worth it. Depends on who is doing the remastering and why. Some of the older recordings are damaged to some degree and need remastering to rebuild what was there. Some were terribly mastered to begin with and maybe it is not totally correct to remaster it so it sounds better but I certainly appreciate that and some are butchered to sound like what they believe the masses are looking for, those I try to stay clear of. One begins to know who to chase down and look for their remastering.
