Break-in is something real and I have never understood why some would argue different. I have tinnitus and am very sensitive to upper mids and highs. My ears are set off with the wrong combo wether a stereo or live music. My ears and tinnitus react differently with the same recording at the same volume as cables change with burn in. This is an objective reality based on experience. This is a physical not physiological phenomenon. Any bit of glare or edge in the critical upper mids and highs sets my ears to ringing and is just uncomfortable for me to listen to for long periods of time.
The same wire that forces me to turn the system off can with burn-in cause me to turn up the volume and enjoy for long periods of time.
Yes, some break-in is for the worse and the end result was not as good as the beginning or mid point. I found that to be true for some Vishay Z Foil resistors recently.
I have also experienced that moving cables in and out of a system, bending, turning etc...requires some time for re-settling in. I found this particularly true for solid core power cables.
