From Tom Fine: "...Why do most test pressings that I've heard sound better
than a bought-in-store version of the LP?
Did the plants do something special for the test pressing..."
Somebody needed to sign off on every test pressing before commencing
manufacturing so the replicators had a huge incentive to make sure they were
My experience has been that the very best pressings were the major label DJ
copies. These were often better than test pressings due to an even higher
grade of vinyl. The first manufacturing run was generally comparable to the
test pressing however reorder runs were frequently done as quickly and
cheaply as possible.
