Yes, Michael told me the same thing. That they burn in each unit and then hand tune them. This was very much the case when they were in Pacific Microsonics where each Model 2 was subjected to this, taking multiple days to get them out. Worse yet, it involved Keith Johnson's ears which made it awfully hard to sell the hardware business after we acquired the company.
Amir do you have anything to do with Pacific Microsonics, like support and such? I looked into it briefly in the past and saw there was someone posting on Gear Slutz that they were the support company for it. I asked Alon Wolf about using it at Munich and he said it remained the best digital he has ever heard.
