Tom, I have seen some Eagles CDs in stores with "digitally remastered" stickers on the front. I don't recall the remastering jobs being advertised heavily like we see with a lot of big-name artists. I've also run across European imports of Eagles albums that have been remastered. Unfortunately, I don't know if
Desperado has been remastered, but it probably has. For the scoop on the sound quality of different versions, I'd do a search on
www.stevehoffman.tv and then post a question, if necessary. This is the sort of question that the knowledgable folks there will be all over.
