A quote from a Qobuz HiRes v Tidal MQA discussion:
Quote
When Mike Jbara, CEO of MQA Ltd., visited Toronto in late June, I asked him if MQA streams and their FLAC counterparts usually come from the same source, with MQA processing being added for Tidal’s Masters versions. “Yes,” he replied.
So no embedded MQA on Qobuz.
