I would definitely check with your local dealer or even call Aurender. AS of now, only the A10 can fully decode MQA. Their will be an update for the N10 and N100 to add what Aurender calls MQA-Lite.
The W20 is highly rated. But I would do a lot of research before I spent $17K.
One can never really stay totally future proof but it seems you should ask the tough questions to Aurender and your dealer.
I know I would.
Good luck.
