Hi, unfortunately the U2 and UAE23 doesn't seem to work with many Android devices. It might work if you use the USB recorder Pro application. Only the Tiny/Android models works easily with (some) Android phones with native music players.

I've been quite interested lately on your Sabre DAC's. More particularly, the asynchronous version. I also have a 2013 Nexus 7 (rooted, with Cyanogenmod 11 on it), with which I intend to use a DAC. The question I have is: does the asynchronous version of your DAC has the same compatibility on Android devices as the other Sabre's?
