As far as I know, PSA does not really support MQA file rendering now in its current line up. Given the trajectory of the format in the marketplace, I suspect its the end of the road for MQA support at PS Audio.
The Bridge II allowed for the full monty of “Origami”, but the AirLens only does the first unfold; which means it’s all about the DAC after that. Again, AFAIK, the DS MK II does not do any further MQA processing/unfolding.
More discussion here:
Hopefully others more “in the know” will chime in.
Cheers.
