<div>Maybe, it's a stupid thought, but...:
could it be that a device relies on beeing galvanical separated
from other devices. I this case the common supply might clash with
the devices concept.<br></div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">This reminds me of a somewhat similar issue I had many years ago: </div><div dir="auto"><br></div><div dir="auto">I wanted a Korg MS-20 and a Korg KR-55 to share one external power puck.
