Hoffman's rep is built on his mastering skills. Nothing to do with pressing LPs. Most of his LPs are pressed by Kevin Gray. I imagine most of what he knows, or doesn't know, is from watching Gray at work.
Kevin
Screw his "rep". If he makes parts for lps, I'd expect him to know how they are used if only to make his own work better. I'm a "producer" but I know how ALL this shit works.
At least I don't make shit up to provide answers I don't know. Geez!
