Here are measurements from 3 separate units of Mage Audio modded DT770s taken using the minidsp EARS. The plush earpads of the DT770 make positioning moderately difficult, but these are pretty consistent measurements across multiple units. Having a wide variety of modding resources available to compensate for stock unit variations and channel imbalances helps a lot.
Here is the Right channel of the stock DT770 Pro 80 Ohm for reference:

The Black Mage is a custom tuned Beyerdynamic DT770 Studio 80 Ohm (Pro 80 Ohm) headphone. The modifications implemented in the Black Mage are the result of creative experimentation, meticulous design work, and hundreds of hours of listening and comparing to many high fidelity headphones.
Externally, the Black Mage is front dampened with a multilayered acoustic filter that attenuates unwanted rises in the upper middle and lower treble to create a more natural sonic character. Internally, it is treated to increase ear cup rigidity and to reduce unwanted resonance. These modifications produce a natural, musical sound signature, a holographic soundstage and excellent instrument separation and imaging.
