[PROBLEM] Digione Signature stuttering

[Cyberguy]

Hi

I have been a long time user of moOde to great satisfaction,
thanks to Tim for that.
  
In December I bought a Digione Signature and a RPI 3+B,
but for several reasons, I havn't got i set up before a few days
ago with moOde 5.2 from image on new Sandisk UHS card.

Now I am struggling with stuttering every 15-30 sec. and it
is a pain listening to. My music is on the same NAS via NFS, as
I always have been using, and everything else is the same,
except the Pi and Digione. I have all set up as it should be
and nothing is indicating any faults.  Today I even made a
new install with latest moOde 5.2
Before that I completely rearranged my home-network/router
and reconfigured my NAS to no avail. 

The Pi 3B is powered via the Digione S as recommended. A
LPS 2,5A 5V for the dirty side and an 1A 5V Supercap-system 
on the clean side.

Before that I had a RPI 2 + Digi+ with just the LPS 2,5A

I think there is something when listening to radio too, but
not as much, and I havn't investigated much.

Does anyone have a clue what to look for ?

Thanks
