I'm not directly tied in with the metal community, but let me tell you a story.
I am not generally known as a "metal" engineer, but some metal clients have sought me out for my approach to sound. A band from Germany called "Necrophagist" on Relapse records came to me because they knew I wouldn't smash a record unless someone asked me to. (Which is the approach of many of our fellow Gearslutz guys so I'm not pretending I'm unique).
Anyway, the story is the band and the label were all going for "good sound with a reasonable compromise". They preferred to have some sound quality and it came out anywhere from 2 to 4 dB lower than the current loudest metal CDs (that is a lot, but the loudness race has taken us to a dead end, with undefined transients, actual loss of loudness and clarity, lumpy bass, small image...). So if you came to me you wouldn't get the hottest CD on the planet, but if it's a good mix, it can become a great master.
For this to happen, the band, the label and the engineer(s) must be on the same page, and the rewards (better sound on the radio) can be enormous. You also have to deal with that penis-envy that comes from "my disc only goes up to 10" if you forget to turn up the volume control!
