Break-in time unfortunately is a necessary evil. A freshly built amplifier will sound quite differently say.. 3 or 4 weeks later. It is centered around chemical changes that happen when power is applied to a given circuit or system to include interconnects, speaker wire etc.
Generally speaking audiophiles that recognize and hear the "break-in" effect are not imagining it - it really does happen. This is why manufacturers may have a break-in shelf for components or sub-assemblies or whole finished products that just have time put on them to try to shorten the break-in time experienced by the customer when he or she receives it in their home.
If you cannot hear the effects of break-in, it usually means that some component in your system is masking the improvement in purity.
The sonic explanation of break-in is the slow but sure improvement in apparent detail and focus of the projected sound stage due to the reduction in timing errors.
