Yeah, I wish there was some sort of standardized indication as to the source of the vinyl pressing. Like the one used in CD: DDD, ADD, AAD.
I automatically assume that any modern vinyl release of new material will have a digital master and digital mixing. So, I really don't care about them. But, on vinyl reissues of albums originally recorded during the analog age, I want to know that the reissue was not recorded from a digital file.
