Heard back from iFi - unfortunately MQA does not unfold through Toslink or Coaxial. Apparently the "MQA Renderer", which is engine these smaller/mobile DACs use to unfold MQA, only works through USB. So that's why all the AQ, Pro-ject, and iFi DACs that do MQA can only do it through USB connection.
So back to other idea - anyone have a Toslink-to-USB Converter?
