saying that drivers wont change over time is ingoring physics.
The break-in is a moot concept not because materials aren’t subject to the law of physics, but because those laws have nothing to do with the perceived quality of your gear.
Barring damaged units, whatever has been tested here will not be acoustically affected by burn-in periods. Sure, the absolute worst speakers
may use materials whom are prone to lose elasticity over extended periods. For instance, certain kinds of rubber starts to deteriorate even if you’re not using them, but again, we’re not talking about durability and quality control. An aging product
may need repairs or to be entirely replaced, so what?
We’re talking about the audiophile lore about products needing break-in to reach their maximum performances. This is the false belief.
• The kind of change happening to your gear with break-in is inaudible.
• To assume that, even conceding a measurable change, it would be beneficial, is just superstitious nonsense. Especially ridiculous if you care to include thermodynamic in your argument. If products changes after break-in, how come it’s always for the better?
Intuitively break-in make sense to the audio community, many comes from a tinkerers perspective and background, almost all males, the same people who may mod or repair their cars by themselves. And now you’ve found something that actually need
break-in, it makes so much intuitive sense to associate that with all our favourite gear… too bad it’s not that simple.
