The current MS600 will not handle MQA, nor will the MS200. Your best bet is to wait until the new products are announced. It is known with some degree of certainty that there will be a replacement for the MS200 that will be MQA compatible and my guess is that there will also be a replacement for the MS600 in due course. I have no idea on timing.

Hector, it's sunny outside. Time to take Golden Ears for a walk and get rid of some of that "bah, humbug".
