letliveThey don't really provide specs for the DAC, besides being rated for HPs up to 600Ω, so technically I can't really tell.
In reality though: Very likely yes. Pretty much guaranteed.
A power output of 30mw/channel at 56Ω is already enough to power the 6xx in 99% of all scenarios, except if you listen at extermely loud volumes.
I assume that the amp in this interface is more powerful than that.
