You need hardware to do a full unfold. Roon on its own doesn't get you there. Bluesound will do a full unfold through its analog outputs. As others said, consider ditching Tidal and go with Qobuz. No special hardware needed. Then you can add an external DAC when you're ready to upgrade and not limit yourself.
How can I add MQA decoding with my current setup?
I currently use Peachtree Audio PreDac and to my understanding this unit does not decode MQA. Short of replacing this unit entirely, I’m looking for a solution to add without breaking the bank. I stream audio from my pc using Tidal. Any info would be greatly appreciated. Thank you in advance.
