I use Apple Music into a Chord Mojo 2 DAC/amp into the Meze 109 phones.
The Chord Mojo 2 Specs are: Micro-USB, optical and coaxial, with charging via a separate dedicated Micro-USB input.
Dynamic range 125 dB A wt.
Noise 2.7 uV A wt., no measurable noise floor modulation
Distortion and noise 0.0003% at 2.5 V 300 ohms
Power output 1 % distortion:
90 mW 300 ohms (5.2 V RMS)
600 mW 30 ohms (4.2 V RMS)
0.06 ohms output impedance
118 dB stereo separation 1 kHz 300 ohms 2.5 V

The 109 Pro phone specs are Sensitivity: 112dB SPL at 1KHz, 1mW and Impedance: 40 Ω.

I understand the Crack is out. The S.E.X. Work? My understanding is I can run a line out from the Mojo thereby using it as a DAC into a headphone amp. Thoughts?

Yes, the SEX amp or the Mainline would pair well with those.  Which you choose depends a bit on your budget and your desk space.
