Last Fault: A 10017 CLASS A LEFT OFFSET

The error has a distinct code so Devialet Support ought to have a quick answer for you. Is this a stereo amp? Any audible symptoms? Most analog amplifiers have a little DC on the speaker outputs. Maybe a few millivolts. Some designs use a tracking circuit to keep this to zero. Small values here are not dangerous, but your amp is sensing that something is out of range, hence the message.
Good luck getting it sorted
