The first, self-titled album was reissued and remastered a number of times, including by some of the 'audiophile' labels you mention. See, http://www.discogs.com/Boston-Boston/master/59355
However, the original album was mastered by Wally T, who was a formidable mastering engineer, so I wouldn't disregard an original pressing. I suspect those are easy to find in the bins, condition may be another matter. Good luck.
