Can anyone here of the tech savvy people tell where the problem lies - that a 861v4 can not be updated to be MQA compatible. One by card modules and firmware update and upgrade-capable, so future-proof premium product.

If an Explorer 2 is MQA capable through a firmware update - then why can't the v4 be enabled for MQA through a firmware update, or at least with a new card a 861v4?

Pure 2-channel operation could not be the reason, in the position DSP stereo we have indeed set up on only two speakers. A device in this price range, with these prepared expandability was supposed to be ready for a homemade MQA update. Or am I completely wrong?
