This is an open question. I hope to see both sides of the equation.

I mainly mean electronic devices, especially amplifier automatic overload protection. But not only!

My problem is that an uncomfortable balance often exists between such measures and sound quality. To be of any value, the popular measures all interfere with sound quality at high sound level, unless they are quite complicated. As in: A fuse (in the signal line) is OUT - far too slow, and becoming a variable resistor anywhere near its blow stage if to be of any value.

I am trying to consider the domestic scene: Equipment usually fairly stationary, cabled up and then left alone, also cables laid so as to be out of the way of the family dog/cat, the family domestic aid, the family themselves. To what extent is it the designer's duty to cater for sloppy home endeavours (e.g. fiddling with loudspeaker cabling while the amp is on)?

It is not like the situation with our cars - their purpose is to be 'around' us in open traffic, where other fools abound in often life-threatening ways. Also the scene changes for the public address operator. That is another story. But for the normal home owner, be he wealthy, lazy, ordinary, whatever.

What sayeth thee please?
