I got the sound to work..... USB settings in piCorePlayer needed adjustment.
it's a different sound to moOde (which is an MPD player), less sibilant but a bit rounded off, not as punchy, or as clear a window into the recording as MoOde.
I read that piCorePlayer/LMS was more about the overall feel of the track, its a pleasant listen, but for me MoOde just leaves it standing, for detail and dynamics.
There are a few more settings I want to experiment with, before making a final decision.
If MoOde had a Qobuz plugin I wouldn't have been looking elsewhere, I like its simple no nonsense and easy to navigate GUI and it sounds fantastic.
I could end up trying to use MoOde again as the player for LMS.
