I have only one LP on Dynaflex, it is pretty thin. They make out in the blurb that it's a huge leap forward in SQ but needless to say it isn't because how could it be?
How do you compare though without owning two different copies?
The only LP I ever bought twice was '461 Ocean Boulevard'. Replaced a CBS 'Nice Price' version with an NM original pressing gatefold. The original pressing sounds quite a lot better.
