No, the 218 does not pass MQA to SE speakers if you enable any DSP processing, such as room correction. You will see MHR delivered to the speakers from 218, which supposedly reduces jitter over SPDIF or SpeakerLink, but not signaling information for a final unfold.

We also need a firmware update for the 218.
