There is a gotcha...

Currently, you can set the MS200 and MS600 (not sure about the AC200) to either pass-through (bit-perfect; essential for MQA) or up-sample (for RBCD). I would suggest that a firmware update would be needed for these devices to *recognize* (but not decode) MQA and not up-sample it, but continue to up-sample RBCD.
