Do speaker cables need a burn in period?

Obviously if the cables aren’t in the right direction you probably won’t hear any differences after breaking them in. The advantage of burn-in will be masked by the distortion. Ditto power cords. This is not rocket science, folks. 🚀 

Yup.  That's one of the wildest claims I've heard this side of gk.

Cargo cultist alert!! 🚨 By the way, god gave you two ears for a reason.

I was actually referring to the "I think we are adults here" comment (should have quoted), but this works too.

Melanesian misanthrope alert!

I had some KK silver KCAG interconnects that sounded a little harsh so I cooked them for 24 hours but no change. I then cooked them for a solid week. Wallah, the harshness was gone. Now what happened? 1. I might have cleaned the contacts by moving them. 2. Some static may have bled out. 3. The power grid may have been cleaner. 4. I might have been in a cheerier mood or by waiting and being more optimistic.
