What Exactly Does "Burn In" do for Electronics?


I understand the break in of an internal combustion engine and such, but was wondering what exactly "burn in" of electrical equipment benefits musicality, especially with solid state equipment? Tubes (valves) I can see where they work better with age, to a point, but not quite sure why usage would improve cables, for instance. Thanks in advance for your insight.

From a teleological point of view, it makes great sense for our auditory system to be good at classifying sounds while ignoring minor differences. You needed to know if a predator or something to eat is is nearby. It wouldn't have served our survival well if we attended to small differences in sound. Audiophilia is but a recent pin point on the evolutionary scale.

My early research was concerned with testing theories of binaural hearing, so I've done lots of forced-choice listening under lab conditions. We can tricked into attending to small details, but we aren't all that consistent in doing so, and variability among listeners usually swamps those differences.

Count me with the skeptics, although I'd swear I can hear break in of disc players.
