Um, the Pro-ject PreBox is a full Decoder and Renderer, no?
@Lonek When the first MQA decode occurs in Roon, the MQA Authentication takes place there too. If the light on the PreBox represents Authentication, then I would expect it to go out. Is there any other text on the PreBox? Elsewhere it has been posted that the PreBox shows “MQB” when receiving a decoded and renderable MQA stream. If so, then it’s rendering.
