HEDD Audio HEDDphone D1 - Frequency Response Measurements & Discussion Thread

Listener has written that the treble of the D1 Is not his favorite (“slightly dry treble”). I finally have The D1 on the way from Headphones.com (waited close to 3 months). Don’t know how to EQ. Could Listener or someone else show me a picture of how to fix this with EQ, for instance with a equalizer on the Foobar player (sliders) or the on the Qudelix. Maybe even how to add a little more bass if I choose.
