I am sure that EVERYONE agrees that Loudspeakers change (hopefully improve) with initial use. The compliant surround softens up with flexing, so that the dynamic characteristics of the unit change. There is similar logical reason to accept that phono pickups "break in".
It's a fact that large electrolytic capacitors (used in power supplies) "form" their dielectric during initial use. Whether or not the resulting change of capacitance has any significant effect on the DC, and any audible effect on the amplifier output is debatable. Film capacitors? Wires? To believe they need breakin a bit of faith is required.
When it comes to inanimate objects like metallic speaker cones and granite equipment racks a whole lot of faith is required. How about the air in the listening room, through which the sound travels? Does it need breakin?
My point is that everyone's opinion begins with belief (for the obvious speakers) and goes down the list of less and less technically-logical situations to some point where you say "that's ridiculous". We may have different opinions about where that cutoff point is.
Who is right? Both of us of course. This is a free country and you may practice whatever religion you like.
