The best way that I was able to discover to connect Ultra HD streaming to an existing high fidelity stereo system is to use a Roku Ultra with the HDMI connected to a small screen to select the song but to achieve a digital output to connect to the DAC of the stereo, the HDMI output from the Roku Ultra has to be connected to an audio extractor, which add an extra level at which fidelity is lost. The ideal solution is to bring back the audio output, either coaxial or optical, from the Roku Ultra. The output should be able to handle Ultra HD streaming (192K). There should be a significant market for this capability, and I for one would buy another Roku Ultra just to have this feature.
