Interesting info from Danny at SD, regarding recording levels, via email:
Me: With the Kashmir’s low noise floor and high dynamic range, it seems to me that I ought to record at quite low levels, then normalize in post.
Danny: I would recommend the opposite. Record at the levels that don't engage the limiter, but are otherwise as high as possible. When these levels are brought down in post, noise floor, if any, is also reduced.
He suggested running a safety on the iso's at about 10db down.
