You shouldn't have an issue using our products with the new Tidal Master service. We've been keeping a close eye on Tidal and the new MQA format that they're offering through their HiFi membership; basically, when using Tidal through it's desktop application, the application itself will decode the MQA file to a 24/96 file that can be read by any DAC connected to your computer, whether it is MQA-certified or not. This basically means that any of our USB/optical DACs (such as the D1, D2, D3, A2+, HD6, etc.) will work great with the MQA files streamed through Tidal Masters through the desktop app.
