Now rocking one of these in my main system after my little laptop I was using (USB to Emotiva XDA-2) took a dump. I mostly stream Spotify and Tidal, but I also pointed it to my FLAC file collection on my network and it synced right up. Can use whatever interface you want or have including your phone, tablet laptop - MAC, Android or Windows that you already have. Went to the local high end stereo shop to see what my options were for media streamers and this one just made too much sense, especially considering the price point and versatility to use it for other things at some point. Allowed me to also clean up the look of things with my main system by removing the laptop and DAC and insert this little cute box instead. Win win. Sounds fantastic and i am only scratching the surface so far until I get me some hi res files to try with it.
