Do speaker cables need a burn in period?

I own a little pile of Morrow cables and never use their burn-in service as I'm always curious about what the differences might be relative to "virgin" cables...so I use my own system to season the cables. My experience doing this doesn't always square with the documentation supplied with the cables, as the differences aren't quite as dramatic as claimed by Morrow...in any case they don't immediately suck and then magically become fabulous, although they do seem to improve a bit. I generally forget about it anyway, and simply enjoy the music...which doesn't seem to be ruined by new cables...amazingly!

I think we are adults here ...

You’re still new here, so you can easily be forgiven for this notion.

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.
