This can also be true for other electronics or components that are connected together in the system.

“Break-in” is more related to the optimization of the individual components or circuit parts that comprise the entirety of the finished product. Depending on the type of parts implemented this can yield a significant change as the process takes place. Often there is a larger percieved or audible change in the first 50-100 hours with more subtle differences beyond. The type of internal parts like capacitors, metalurgy or in the case of speakers the driver design and materials can all influence the time necessary for optimization.

That aligns with my experience.
