Cable burn in

I have repeatedly said that I definitely believe that audio electronic components will change in the first hours or even weeks of operation. I can see a definitive case in point where electrolytic capacitors change over time. Initially their capacitance value will change fairly rapidly as the ‘forming’ process stabilises. After this point the minor properties (such as DA, ESR and possibly self-inductance) will continue to show reducing changes over a longer time. It is also likely that there …

BTW your editing of my text lost the fact that the “very much” referred only to the first example, mechanical compliance changes.
