How important is the recording side to you?
With your headphones being on the mid-high impedance side, the greater flexibility and higher output levels achieved by combining a $100 interface like the Minifuse with a $100-ish headphone amp (Schiit Magni Heresy, JDS Labs Atom Amp) as an "afterburner" may be worth it, there's really no interface with that amount of output. As good as the M2 is, the headphone out tops out at about 3 Vrms, which should generally get the job done but in a production environment you tend to need some more gain than in playback (as a rule of thumb, I would should for maybe 6 dB more output than playback baseline, which would generally be ~2 Vrms for your kind of cans, so ~4 Vrms).
For another all-in-one solution, the Audient iD4 / iD14 MkII interfaces would provide more than enough output, just as long as your computer sports a Type C USB connection.
While the trusty CS4272 sports a more modest DAC dynamic range than the more modern options, it is still good enough when combined with an analog output level control, it's not like you need more than 108 dB(A) worth of instantaneous dynamic range very often anyway. As a rule of thumb, you want the noise floor in headphones to be <20 dB SPL, so you could have the volume adjusted to be hitting 120 dB SPL peaks here (which is more than generous and about 8 Vrms into HD600s) and would still be fine. If you have a fancy DAC, you can merely do away with some complexity in the analog stage as well as pot channel tracking issues.
