Just a little FYI ... I just received a Khardas ToneBoard & wanted to let others know that it works with a Nvidia Shield 
Hi ! i have a
nvidia shield 1st generation (i see
p2571 on the bottom of the unit). I cannot even complete the installation process.
It does not accept my gmail credentials ... very very weird ...
I bought it years ago and never opened. Do you have the same model number ? is on the bottom difficult to read ...
I was using a HDMI audio extractor to get 2 channel audio to drive a stereo ... haven't yet made any comparisons between the two.
Has anyone else used a DAC with their Shield?
not yet with the shield ... but with another Himedia android tv box i was able to use a usb to spdif converter (Gustard U12) and then to feed a dac and the resulting sound was quite good.
The dac was an apogee rosetta 200 with an internal reclocking system i think.
I do not know if it is possible but i would try the usb to spdif conversion route ... i have also a Melodious unit to try out but i cannot even finish the installation process
