Do speaker cables need a burn in period?

I have an experience I want to share with you guys. Yes it also takes time to break in a new cable. When it is broken in then don't feel safe like that when you buy second hand. I have bought second hand speakers and cables around the country (Denmark). Listen to it before paying and later transport. In winther time and if the speakers and cables are exposed to cold weather something happend to them. I have a van where the storage room has no heat. Typical transport time below zero can be from 1 to 4 hours. The gear that has been exposed to these temperatures do change their sound characteristics. Speakers that sounded good suddently sounds terrible and need to break in again. The same goes for cables. Happy listening - to music out there :-)

Cables should always wear their winter jackets when going out in the cold.

In a court case that would consider what is being claimed here  circumstantial evidence would be admissible from experts not from every Joe that claims he hears a difference. For every Joe you get who claims he hears a difference there is a Joe who claims he doesn't. Good luck finding enough experts on wire, i.e. scientists without a vested interest, independent experts not cable manufacturing shills, to support the notion wire changes over time due to the amount of energy passed from an audio signal. Cable manufactures can make their case to support their marketing claims using their experts but that's not the same thing and wouldn't prove anything. It is enough to keep them from being sued for some of the outlandish claims made since it's understood to be subjective opinion not an objective fact. 

I have not seen these outlandish claims cable manufacturers make. What are you guys talking about?  Can someone do me a solid and post some of them. I want to viddy them with my own eyes 👀 Share! Share!

I think the nonbelievers are overlooking the circumstantial evidence of the vast numbers of listeners that can tell a difference and the cable manufacturers that spend untold thousands of careful listening hours to perfect their products while listening to burn in.. In a court of law would this prove burn in is not a fallacy but true? Known science would be taken into consideration.

>>>>>I hate to judge too quickly but my sense is that naysayers aren’t really interested in evidence. Whoa! Did I just say that?! 😳
