I gave up EQing a while back as I didn't find it neccesary and enjoyed the flavor my various headphones brought. However I thought I'd give it a go again for fun.
I'm listening to my Andromedas out of the ADI-2 DAC Phones Out with the Harmon 2017 EQ presets applied through Equalizer APO... Finding it very enjoyable. The EQ adds nice sub-bass boost and cuts out some unnecessary warmth, also adds more sharpness/accuracy to the stage and added smoothness in the highs.
Cheers.
