cable burn in process

Hi folks, do you also share the same experience regarding cable burn in process? A not yet broken in interconnect (or speaker cable), right out of the box sounds during the first 10-20 hours of listening quite good. We are hearing some or the cable's characteristics and how it would sound when fully broken in. After 10-20 hours the sound gets worse, the cable sounds totally off. After >50 hours (a few weeks of listening) the sound returns to baseline, but with more body, smoother treble and bigger soundstage. This is a phenomenon which I have encountered many times during my cable journey. I believe cables need burn in time, but the sonic changes in this particular order remain one of the mysteries of audio.
