I would recommend a miniDSP SHD Studio which operators entirely in the digital domain and has an excellent selection of inputs and outputs for high-fidelity digital signal transmission.
Then you can take advantage of Dirac or other DSP and routing features while matching it with whatever other gear you want.
We carry miniDSP specifically for the SHD and SHD Studio products to support more complicated setups with Dirac. Learning REW is unnecessary for Dirac, but is still a good skill to have and can be helpful for things like subwoofer integration which 2-channel Dirac can't entirely address on its own.
