Multiple copies of the same album on vinyl?

Guilty! I have many multiples of some of my favorites. Some examples are: New Riders of the Purple Sage "Panama Red", "NRPS", Allmans "Eat a Peach", Grateful Dead "American Beauty", "Workingman's Dead", "Blues For Allah", and more classical album duplicates than I can count.

I own most of the 180 gram offerings of old R&B reissued by Four Men with Beards as well as MFSL and others.

Fortunately, I also have every album I ever bought (beginning in 1967), so there are lots of duplicates. At the risk of starting a firefight, the reissues, IMHO, are rarely sonically superior.

Yep. I have only three dozen in that category, but that is down by a remarkable fifty just because they were destroyed. Not 'went bad' as you say kindly, but were ruined. Even my wife agrees that it happens enough to buy the cheapest insurance you will ever see.
