I am using it from July last year. While the headphone out is decent, the lineout audio seems like a bit low. I get a better output when I stream the same song using my Yamaha Wifi player. The advantage is that this can be used as a headphone dac as well as a desktop dac. The downside is it has got only USB input. In my case its fine because I am using it primarily with my computer+Roon or Foobar, Plexamp.
