A question of power


I have never used power conditioning as have never felt the need to. But as I move up the fod chain of equipment (still not very high) I am thinking about what unregulated power does to equipment.

In testing for the power at my home, I exceed 120 v quite regularly! I know most people have a problem with sag, so this is where my question is focused... does an overage (say, up to 131 v, which is the highest reading I have over the one day I tried it) do bad things? To the sound, to the life of the equipment, whatever? Might it even improve the sound or is that wishful thinking? Incidentally, the lowest reading I got yesterday was 127 v.
