@bagwell359 and @rev6, the graphs I posted are the raw uncompensated responses, they don't show how we 'hear' these headphones but instead show how they measure on the miniDSP EARS rig. I personally don't trust the HPN and HEQ compensation curves supplied with this rig but if you'd like me to upload the compensated measurements then let me know and I will (see post #20,902 for example, where I already posted compensated measurements of my HD600). However, it won't change the result that shows my HD650 has more upper midrange and less treble than my HD600, this difference will remain no matter what compensation curve is applied.
When I measure headphones on the miniDSP EARS rig I prefer just to stick to the raw uncompensated measurement and use my HD600 measurement as my mental baseline of 'flat', and then look at how the other headphones deviate from the raw measurement of my HD600. However, I appreciate this won't make sense to readers who aren't familiar with the miniDSP EARS rig and/or aren't used to seeing raw uncompensated measurements.
