Auralic Aries to Roon

The Aries requires a separate Roon core server.  This is where connections to outside music, and your library happen. It is also where any DSP gets applied and what will talk to your phone/tablets. With multiple output devices, the Roon core would need enough CPU power to run them all, which is why it's not always incorporated in end-point devices.

My computer is the Roon core and iPhone the controller. The core just won't recognise the Aries. It recognises my phone and a borrowed Zen Stream .

Of course, one alternative if close enough is to use a USB connection between the PC and Aries.  Suggest a USB isolator if you do this though.

Not possible -  PC in the office Aries in the media room.
