Turning Off your Devialet

[Axel]

Surely in this day and age we can expect our electronics to last a very long time, no matter whether they are left on or not?
I have never had a bit of kit die on me. Some held for over 25 year and still work when I plug them back in.

Same here.  Never had any equipment die on me in the last 45 years of HiFi.
As for the longevity of Devialet gear: we'll have to wait and see!
