They can't be Roon endpoints since they don't have an Ethernet connection, butt they might act as very good buffer between a device acting as both a Roon server and endpoint that is connected to your DAC over USB, such as a PC, NUC, or Nucleus.
I'm considering selling my streamer and connecting my NUC running ROCK to a Gaia and then using I2S to my DAC (Terminator).
