Sennheiser HD 600 on a MOTU M2 headphone output
Loud enough for everyday listening, with little spare for peaks. The M2 reaches about 107.3 dB on the HD 600. Those are the published figures.

The MOTU M2 will play the Sennheiser HD 600 loudly enough for most days. What you do not have is a comfortable reserve when the music suddenly gets much louder.
The HD 600 is 300 Ω. Reaching a 110 dB peak — a loud moment in film or classical, not a casual average — takes about 4.47 V from the source. The M2 gets to 107.3 dB on this load.
On compressed pop you will not notice. On classical or a film mix the volume control will sit high. Buy a headphone amp if you want those peaks clean. Do not buy one because someone said every 300 Ω headphone is impossible from an interface — that is not what this pair does.
