Streaming hirez from Qobuz
Streaming Hirez from a server
Or buy an MQA capable dac, as Mytek, Meridian…is you want to stream specially MQA in fully mode.
As I understand it, Audirvana supports Tidal MQA, but if you want full support you will need to change the DAC for one that supports MQA. Personally I would ditch Tidal and switch to a Qobuz service which will give you lossless hires streams.
