I too bought Paul's Boutique and it mostly failed double blind testing for me. There were a few times I could tell minor differences, but I'd even struggle to say it was actually an improvement one way or the other. They seemed an odd, at best, candidate for remastering. However remastering is, a lot of times, just an excuse for repackaging to get hardcore fans and collectors to buy more stuff, which they are happy to oblige. Some albums legitimately need to be remastered, most of the Beastie Boys catalog don't and these remasters are proof of that.
