Sure, but for headphones the elder Harman reference is smoothed. So you never know if deviations are to be appreciated or should be considered to be flaws. The new Harman, not officially released yet as far as I know, shows more features. It allows to match the detailed headphone's output better.I smooth my measurements less than research/target to see more detail. Going beyond that will give you perceptually false information because our hearing bandwidth enlarges as frequencies go up so a lot of variations are not audible. This is true for both speakers and headphones.
That's very much true. Wasn't it done already, I wonder.You are talking about a research project, not a review.
