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.

I agree with @whart on the old JVC vinyl. Looking forward to my Marvin Gaye pressed on the latest vinyl formulation from MOFI. Hopefully it won’t disappoint.

Regarding QRP, there vinyl formulation (may ?) be quiet, their pressing quality leaves much to be desired, especially after the big press releases vs. the end product. SQ is mostly very good but overall, I’d say it’s a big disappointment.

Thinking about this brought back memories of years ago... I either started a thread or just posted about an idea for an across the board high quality vinyl formulation that every manufacturer would have to use. The premise being...that for the end user, we'd have the best vinyl available at all times. The only difference between record labels would be the recording quality. This fund would go toward one goal only...to have and invest in the absolute best vinyl formulation possible.

A fund could be started by the record labels with what they'd normally spend on vinyl. Then maybe, the end user would, pay a slight premium or be on a subscription service basis for vinyl purchases w/ some of those proceeds going into the fund for quality vinyl formulation. I'm just throwing out ideas here folks. But I think if there was a uniform quality vinyl formulation that was required for all records made, we'd be in better shape.
