Technical and scientific discussion of amps, cables and other topics.

This is all about rare events.

What is the likelihood of a power fault? Just sitting there, a component that is made well seems like it should be safe. However, what if there was a mixup between the design departments of the marketing and OEM companies that led to a 2-watt resistor being installed where the dissipation was over 2 watts, and the circuit board was slowly being cooked? (Don't laugh, this example is based on a true story.)

What is the likelihood of a guest spilling a drink into the amp during a party?

What is the likelihood of a thunder storm causing a lightning strike on or near your house? A house I lived in for 9 years was struck the year after I left: it was under a power line with a grounded top conductor, and at the bottom of a hill, so I thought it was safer than other houses around it.

My point is that you cannot dismiss this safety concern because the events that would make it an actual hazard seem to be improbable. You cannot calculate the probabilities.
