Do speaker cables need a burn in period?

Nothing stinks like 🐈💩.

I can't scientifically prove what I hear is real. On the other hand I can't unhear what I have experienced. The Kimber ICs I have are very fast and detailed. When I put them in my system my body would jump at start of "Hey You" by BTO. The Tara's not so. 

Stop the presses!! Audioquest explains cable burn in. And guess what? It’s not really rocket science. 🚀

“A highly misunderstood area of cable performance is the subject of cable run-in, sometimes (inaccurately) referred to as “break-in.” “Break-in” properly applies to one-way mechanical phenomena, such as a motor or a loudspeaker surround. Cables and capacitors do not “break-in”, rather their “dielectric forms,” meaning that it takes time for the dielectric material to adapt to a charged state.

This process is quite audible and explains the signi cant improvement heard in electronics, loudspeakers and cables as signal is applied over a period of time. It has long been noted that cables (and all audio com- ponents) sound better after having been left turned-on for a number of days. It has also been noted that once turned off, the component or cable slowly returns to its original uncharged state. For many music lov- ers, this means that they are almost never hearing their cables in their optimum state.”

Why is this not scientific proof.
