Power Off, Safety Question


For many years when changing cables/ICs between components
I have followed manufacturer manual advice and turned main
power switch on units off. No mention was made about also unpluging units so I just turn them off, but left them plugged into power source. Is there any reason why units
should be turned off "and" unplugged or is this overkill
and unnecessary?

A related question when changing cables between two components does entire system have to be turned off or just
the two components getting the cable change?

I confess little electrical design knowledge but would appreciate members thoughts on this.

I agree with Grumpybb and would add that when you power down you should turn off your pwr amp off first and then everything else. If your pre has a mute switch use it as well. Reverse everything when you pwr up again.Good listening!
