Trialling Roon - how to optimise SQ

The kind people at Roon have allowed me an extra month’s trial as I have recently acquired a Linn Majik DSM. Roon Core operates from my iMac ,which is not ideal I know but it works for the trialling purposes. The Mac is hardwired to a router → NAS drive → DSM. The signal path is usually shown simply as Majik DSM → Source Flac 44.1 KHz i6 bit 2Ch → Linn Streaming. What I would like to know is how best to optimise the SQ using the Roon settings and / or any Linn settings. If anyone else use a Linn streamer perhaps they could give me some tips - thanks.
