I've also found a correlation, although compared to the number of albums on the database I only have a small sample.Nothing in any of the posts proves anything. Contrived "tests" and unverified hearsay is all they are. The DR meter is just math that compares peak to RMS and is no doubt flawed and abused but it is based on reasonable mathmatical assumptions and I find strong correlation between the DR values and percieved loudness. Preference of course is another matter. In an era of ever louder and more compressed music the DR values do provide some useful information especially with the online database. Knowing that a tool is limited and imperfect does not mean it is useless.
Obviously as a guide to vinyl DR it's useless but no-one is disputing that,
