I'm also interested in the Holo Audio Red for my second system. I'm planning to use it with Denafrips Pontus II DAC. The fact that the Red has an IS2 output is a big plus in my book. However, based on my understanding, the Red cannot be used as a streamer AND a DDC simultaneously. To use it as a DDC, it must be connected (USB in) to another streamer or Roon core.
Can someone validate if my understanding is correct?
