It's more akin to my HTPC with Skylake processor that I built in this room for home-theater multichannel purposes (Dec 2015) feeding my Onkyo HDMI receiver.<br /><br />Remember, this little computer is basically being run as a headless machine for ethernet streaming, output as USB to the DAC. Much less CPU processing than your Broadwell NUC.
