How much does vinyl formulation have an influence on overall sound?

Another point is how many plays they will tolerate without significant deterioration. I do treat then with LAST so I may never know.
Interesting to compare original US Bitches Brew by Miles Davis and first release Japanese. Japanese vinyl is definitely quieter and EQ is better overall, at least for my taste, but Miles's trumpet has a little more power and presence in the US version. I listen to them both.
