I have never found a reliable guide. The best thing is to follow recording and mastering engineers. When you find someone who is good or you like (such as Doug Sax, Chuck Ainlay, Al Schmitt, Jack Renner, Michael Bishop, etc.) Then look them up on artists direct and find out what they worked on. Generally the good guys get more say in how it sounds....i.e. they get more respect from producers who leave them more freedom. (A producer will often push around a lesser known engineer to produce a hot CD = compressed and bad sounding CD)
Good luck!
