Do speaker cables need a burn in period?

What is "data dogma"? I don't recall Feynman pointing to that as the cause of the Challenger wreck. The data was, in fact, abundantly clear. Challenger and Columbia were the results of very poor management decisions, pure and simple, and anybody familiar with the investigations would know that. Columbia shouldn't have stunned anybody given that it came back from the maiden flight beat to hell by garbage falling off the tank. 
Maybe you'd care to point to an actual example where the real numbers and engineering led to a false conclusion. Data doesn't produce dogma unless idiots look at it and presume it to mean things they don't understand. That's how you get theories on wire directionally and cable burn in. 

Feynman’s contribution to the Challenger Disaster Final Report was disallowed until the very end when it was put into the Appendix as a sop. He was kind of a loose cannon. Not unlike some folks here. I’m not going to point fingers. 👉 👉

I think data is only part of the equation. If anything, data
probably comes last. If you want to build anything, first you
need a vision, some intuition, and some sound underlying reasons.
Then you build a prototype. Then you measure and collect data.
If it were data, Einstein would not have come up with his general
relativity. In fact, people were not able to prove his theory
back then because nobody was able to measure time and space.

To demand data or all else is like abdicating your mind. The
world is too complicated for data sometimes. You have to rely
on your tuitions a lot of time.

As going to the moon, I think data probably comes way after
a bunch of people getting together brainstorming throught the night.
Can you imagine one guy stood up and said "I ain't going in that rocket
cause there is no data telling me it won't blow up."
I am sure another guy would say, "But George, we ain't got a
rocket yet so somebody has to go first".

Audio is by and large a subjective hobby. If you want a hobby based on measurements go build houses or race cars. 🏎 

What!?!?!? No... Data comes FIRST. No technical challenge ever solved got solved without first defining the problem in technical terms using data.
