Roon Nucleus has no DAC, it is just a server. It has a USB output to hook up a USB DAC. I bought one recently and as a plug and play server I like it but not what you are looking for.
check out the new Bel Canto e.One Stream. It is a music streamer that’s MQA compliant and has a built in 24/192 kHz DAC. It also lets you add a Stand alone DAC using various digital outputs. It has native Tidal support and also is Roon compatible. So out of the box it does Tidal MQA using its own app, and expands to enable Roon and third party DAC solutions if you so choose. Only thing it can’t do without a third party DAC is DSD.
