Yes, it should be just fine!
I’m not always the best at reading amp output specs either, and they often only give them for one ohm rating which can be frustrating because then your left to do the conversion math yourself. And until you’ve actually listened to the headphones yourself, the power output ratings don’t necessarily help either. Sometimes those numbers are fudged, or have little actual bearing on your real world experience.
But a quick glance at Lexicon’s product sheet for that interface shows that they’re confident the amp will power “any headphones,” and that’s not a claim they’d probably make lightly without severe internet recourse, hahaha.
Plus, most audio interfaces these days include capable headphone amps. It’s not that expensive at all for them to include the required components in spite of companies wanting you to think that it is so you spend thousands on headphone gear. :)
