I think he makes a good contribution to vintage sound. He only knows what he knows, which is far more than I do of course. I read his stuff as just a single source of info on any piece of gear I run up on. Took a while to decipher his style of writing, or rather note taking, which apparently takes to much time for him to edit to text. I hope he keeps it up. His opinion is like sound itself, subjective. Please pass the salt.
