FR CURVE WARNINGS
Quick note on FR curves: even the best artificial heads can't consider YOUR concha (mids), seal (bass), direction (highs), ergonomics and your ear or fit for comfort. So take them with a grain of salt. We only use them for comparisons in our different revisions and QC purposes such as testing variances from unit to unit and tracking (L/R variances). It has VERY little to do with the sound.
We use them a lot in development but only test with real ears and lots of them, the best in the biz (my team and you!). My team listens very carefully and we then try to GUESS the FR curve afterwards. Many times we are wrong, but our EARS hear different.
In fact, we had a M-100 that MEASURED way better in testing that "looked" perfectly flat. But it sounded really bad in comparison to our "golden unit". I still have it, I can demo it sometime and show you the FR curve vs final MP units. Sometimes consumers/reviewers look at the FR first to make judgments, you need to AB test and listen THEN draw what you think the curve is by hand. Then you compare it to the machine. Check out even Reviewed.com and InnerFidelity and how high they rank M-100/LP2 by ear.
It is crazy how many times it is off! I need to build a better FR machine someday that considers 20+ ears/head shapes and averages them out for "greatest sound for greatest people".
