These are all Linux devices.On another note; I noticed that when you order one of these DACS it will ask to specify what is your operation system (windows, Mac and Linux).
I use Mac but in most cases I use streamers from Lumin, Aurender and SOTM so will these three devices be plug and play or a software has to be downloaded >> thanks!
In any case, the request is so they can set the firmware to one appropriate for Windows or Linux to get maximum resolution.
