You could also experiment with feeding the Devialet a clean USB power and ground using for example a Mikrotik 5v USB Injector plus a +5V linear PSU or battery power (e.g. Anker E4/E5 1st generation power bank). I use a dual headed USB cable (Kingrex) for this purpose but if/when people already own a high quality USB cable this could improve SQ as well. These types of Y-cables are also offered by JCat, iFi, YFS, Revelations Audio Lab, Light Harmonic, ... etc. I'm sure the bigger brands will follow later as well.
