You know, i wanted to get that one, posted here on the forums but i was discouraged to pick it up, on Headfi i was told i should get this one instead:

Sound out of the line output was so good, crisp, but the headphone out had a constant hum, almost like a ground loop, so in the end i returned it.
Not necessary, but it would be nice to have!
