Thanks.
I suspect what I'm hearing is because of the remastered version. Dynamic range probably compressed all to heck. I'm not into vinyl but I will look up the dynamic range of available CDs and see what I can find.
However, several versions of U2's Achtung Baby sound similar too me. Muddy might not even be the right word; just overuse of bass in the production....and I like bass. That album has nothing in common with Siamese Dream but is from the same time period.
