I believe that Toslink missing is specifically on purpose. Having a MQA Toslink interface on the cheap is not what M wants.

I've watched the YouTube video with Richard head of engineering explaining the DSP SE and EBA... I believe that those DSP are a great part of the MQA standard ... Time alignment is in the speaker I thought was due to their new view on the DSP speaker side for the greatest part.

And Richard telling that bass time alignment problem not affecting small speakers like the DSP3200 was an eye opening. I know why I love monitor size speakers.
