The 210 is telling the DSP speakers over comms that IT has Decoded and Authenticated the MQA file.
So the DSP know that this is an Authentic and unaltered MQA and state as such on their display.

Because the Bluesound isn't a Meridian product, it can't communicate over comms with the DSP.
They do receive a file which looks like a decoded MQA so they render it.
However they're not sure that the file is Unaltered or Authentic, so don't flag it as an 'MQA' but 'OFS'
