Do speaker cables need a burn in period?

Even if they're been used before, or cooked prior to shipping, they still need time to "settle" in the new system.

Every cable needs burn in how long depends on the gauge.I just burned in new Furutech speaker cable about 200 hrs to sound its best.Anyone who says its bs never had a real high end system.

Components and cables seem to be affected by a 'breaking in' period.
What seems to be a simply electric path has subtle intricacies that, in the end, affect sound reproduction.
It seems like it would make a great thesis in EE.

For mere listeners, like myself, I just recognize the effect and play music.
When 'it' happens, I am a happy guy.

Absolutely! My QED Signature Spk. wire sounded pretty good from the start but it wasn't till about 150+ hrs. when "it" happened. Glorious sounding cable especially for it's very modest price. 

Yes!
