I'm just curious if the Fireface UCX has enough power to drive 600 OHM headphones to sufficient volume levels for mixing or if I'd need an extra headphone amp for this?  (and yes I know headphones are not ideal for mixing, but I'm in a place with some pretty thin walls right now and don't really have the luxury of using good monitors).

I have some budget constraints at the moment, and while a Babyface should cover most of my needs this instant, it won't drive my headphones.  If I end up needing a separate amp one way and not another it might make sense to stretch a little further and just go for the Fireface UCX, which does offer a few things I wish the Babyface had while also being something I could grow into as my needs expand. 

Appreciate the advice!
