Why can I not get rid of MQA out to my DS1000 Streamer / DAC.
What is your concern? If you just don’t like MQA, the best solution is to downgrade your TIDAL account to their HiFi plan, which has no MQA (also will save you some money). Or, you could switch to Qobuz.
Here, Core is just authenticating the MQA stream and then passing it on to the DAC with zero additional processing.
