It all depends on how bad the original mixes were. The remixes of the early Zappa catalog are tremendous. Same for the early Zeppelin records and the early Pink Floyd records prior to Dark Side. By Dark Side they had gotten the Hang of it and were making great mixes mostly because their equipment was much better. There are still several ways to mix an Album depending on what format you want to sound best. An LP mix will not sound as good as it could in High Res digital.
