Exactly! If a designer has made a circuit using components that will 'change' - then the manufacturer will ship accordingly - and not leave anything to chance.
If a designer has used circuits and components that they know won't change then it will ALSO be 'right' - 'out of the box.'
(I'm referring here to the 'changes' implied by those suggesting the 'dramatic' changes that happen with 'break-in' - as if the manufacturers were selling half-baked bread - I am NOT referring to component changes that probably do occur over years of use that may or may NOT have any noticeable differences in sound anyhow)
In any and every case, a skilled dessigner will KNOW what's 'up ahead.'
