As for Doug Sax, the studio world is in another galaxy. Doug probably uses near field monitoring and ESLs are just too big for that environment. I would bet that he never even tried them. Doug does not do recording. He is a mastering engineer (and trumpet player) He takes the tapes and mixes them down to 2 channels. IMHO the best job he ever did was Tower of Power Direct. Great record. I think he did most if not all of the Sheffield Lab records.
Interesting comment about Mr Pearson. So much for audio philosophy.
