I think for the OP the intersection of synergy with current DAC, simplicity, flexibility and future upgrade paths lies with the upper tier options from Innuos.
Having the new Innuos streaming software, easy CD ripping, album management, server integration and sound quality is pretty solid. You can add Roon down the road if desired? I tried Roon but found it did not solve any problem I had. The cool magazine browser like functionality is fun though. I decided to stay with my Linn Akurate system.
