Do speaker cables need a burn in period?

Cable burn in service "for free".  Oh wait it doesn't exist.  Its interesting how one is willing to disprove oneself.  

Nice try.

Free burn in on all cables on their custom cable burn in unit (and they are not $7,000 cables):    https://www.avantiaudio.com/cable-conditioning.html

Cable loaner program (prices start at $700). Cables are burned-in before shipping:    https://www.taralabs.com/cable-loaners

Only charges $10 using off the shelf device (one built for MFG would be much less):   https://completecableconcepts.com/collections/cable-conditioning

That was just a quick search. It is a marketing decision, and it could be done very cheaply in production.

Economics in Eight Words: There ain't no such thing as free lunch.

I think we are adults here, and obviously there is a cost to everything, but the question is and that is being discussed, is what is the real cost to a MFR, and is it justified for a reasonably priced cable. I have shown that with minimal equipment, a burn-in cost of a few dollars per cable is reasonable at fairly low volumes, and hence could easily be incorporated into product price of a cable in the mid-hundreds, not mid-thousands.
