I know...
The best way I have found of identifying good masters is by year or credits. Usually, the earlier the pressing, the better it will be in terms of dynamic range.
For credits, I look for labels I trust like Audio Fidelity, MFSL, DCC, Chesky, Sheffield Labs, etc...
I also check for the following names:
Steve Hoffman
Alan Yoshida
Roy DuNann
Barry Diament
Kevin Gray
Joe Tarrantino
George Horn
Paul Stubblebine
George Massenburg
Keith O. Johnson
Bob Ludwig
Bob Katz
Larry Walsh
Doug Sax
Ron Furmanek
Bill Inglot
As for the Rolling Stones - Tattoo You...the first pressing black triangle is the best version in terms of dynamics but it needs some serious EQ work as it sounds very thin.
