Do speaker cables need a burn in period?

Whoa there people. I, for one, believe in burn in but not the outrageous pricing of cables. There is a lot of gray area here so generalizations should be greeted with about a pound of salt, when they occur. 

There's lots of overlap in these discussions that seems to be glossed over or neglected for the sake of a point. 

I've mentioned this before, but it bears repeating. My current speaker cables are designed by a former Belden engineer, required break in, and were very reasonable in cost.

There. I've covered three areas of contention with an acceptable solution.

I believe Blue Jeans cables use Belden.  I bought a set of QED for not a lot more money than Blue Jeans cable but easily better considerably.

I have no problem with Belden. As long as it has Teflon or air dielectric, is cryod and is controlled for directionality. 

I believe Blue Jeans cables use Belden.

Correct.

I bought a set of QED for not a lot more money than Blue Jeans cable but easily better considerably.

So you had Belden cables and thought QED sounded better?

It sure would be interesting to see if those impressions held up if you didn’t know which cables you were listening to.  I'd also wonder about your explanation for why one would sound "better" than the other.

I was subjectively "sure" my new music server sounded distinctly brighter and different from my old one. But in a blind test I could not tell one from another.

Same as when I blind tested some expensive AC cables against a cheap one. The expensive cable at one point seemed to alter the sound of my system. As soon as I didn’t actually know which cable was being used, the "obvious differences" between it and a $15 ac cable disappeared.

Blind testing can be sobering, and educational, that way ;-)

You didn’t really answer my other questions, though.

IMO Teflon was and remains overrated. I perceive that I hear a hint of a “sheen” (no, not Charlie) from cables made with Teflon dielectric. One of those irritant-over-the-long-haul things (not unlike Charlie). My preference is for cotton or foamed PE, regardless of direction.
