The Ministreamer is just available as an internal board. It is good up to 96/24 only.
For higher bit rate use I would recommend the Kingrex UC192 which works up to 192/24 and comes with software drivers for PC computers. It does not need drivers for recent Mac computers.
It is in a small external chassis, complete with wall wart power supply, USB cable, driver disc, and instructions. It has USB in and coax digital out, and more. It works very well with any Vision or Fet Valve DACs.
USB 3? Digital is moving nearly too fast for me to keep up with.
