I think I have an answer by elimination. Both using core audio.
I used the Mac Book Pro on my Devialet 250 via USB and exactly the same problem.
Then swapped the USB connection to my 2012 Mac Mini (which usually drives the Devialet via AIR/Audirvana) - absolutely fine.
The difference?
Mac Mini 10.11.6 El Capitain
Mac Book Pro 10.13.6 High Sierra
So something weird on the OS side.....
Any ideas how to fix this?
