I have had problems with MQA clipping during playing MQA files.
It sometime drops down to CD quality and after a while its back as MQA again.
When playing in cd or hifiquality it is working perfect.
I am using a pc as a core with Windows 10 and have upgraded to latest firmware from ROON.
From PC i use Project Strean box S2 Ultra and after that to Project Pre Box S2 Digital.
