Behringer SRC2496 as a HP amp?

[BmWr75]

I have one of these units that was modded by AudioSmile to improve the DAC capabilities.  Don't know if these mods affect the HP output, but I've been using it as a HP amp with Beyerdynamic DT770/600s and DT880/600s and it sounds pretty decent.  Anyone else have experience with the SRC2496 as a HP amp?

Am listening to my new AKG K702s with this amp/DAC.  They sound amazing together.  The bass on these open phones is excellent.  The detail is spectacular.
