I never turn my hi fi stuff off (except valve stuff). Found out long ago while working for major computer companies that failures generally arose after switch off, switch on. I know others will disagree but this is experience of hundreds of thousands of electronic components, worst being routers.
I do switch everything off if I’m going away for weeks at a time.
One company went to the extreme of using “burnt in” chips........they failed in just the same way.
Components due age and fail prematurely but I guess it’s swings and roundabouts.
