Hi Lee,
Certainly there is point in using 818v3, 808v6 or 218 with Non-Se speakers.
These items will receive the MQA file and render it to the best that these speakers can receive (96/24) MHR, an improvement over simply upsampling the CD part of the MQA file.
They will do the job better than simply using the tidal app to decode and taking digital direct from a PC.
This wouldn't change with a firmware update for non-se speakers. I'm not expecting any 'MQA' firmware to be released for them.
Depends how the AC200 is used, it would still provide additional inputs over those in a 218, so AC200 > 218 > DSPSE speakers would work fine.
