It is very good, so I don't think you will be disappointed. Be sure to flash the latest firmware once you get it though, tutorial and files are found on ASUS' website.
Also, there is a slight imbalance between the left and the right channel on the three first steps on the volume knobs (individual knobs for XLR/RCA and headphone out), but you won't be having it that far down when listening anyways. Don't know if that applies to all units, but it is that way on mine.
