The Roon architecture of Core, Control and Output components can be distributed or all on the one box. Roon themselves state that the best results in audio quality can be obtained by a distributed setup, but recognise that the convenience and flexibility of a one-box solution are also valued along with sound quality.
If the one-box solution of Innous delivers sufficient SQ to please its customers, then it will have succeeded in balancing convenience and flexibility along with SQ
Just noted that on Antipodes devices the same is possible. Antipodes also claim that the SQ is noticeably superior under the one box scenario in some setups. YMMV.
