Do speaker cables need a burn in period?

I still get a chuckle out of this.  Worth a read:

Not very surprising as Monster Cable is crap. In fact, I’m surprised the Reynolds wrap was not judged better than Monster Cable. Now, if he had evaluated Reynolds wrap vs high end cable and got the same results, that would be news!

This is the biggest list of snake-oil, pseudoscience i have ever seen on this site.  

1. Send them off to cryo lab. While many high end cables are cryod by the manufacturer, Cryoing twice is better. Once you get them back from the cryo lab give them about a week to recover from thermal shock before critical eval.

What happens when these cables return to normal temp?  can you document ANY physical change in the wire and how it could impact how the AC current benefits from it and PROVIDE it!

2. Establish correct direction.

How would one do this with audio AC which is completely random AND moves in both directions on the wire continuously!  

3. Burn in using burn in track or burn in device.

Ridiculous, there is no scientific proof that cables have a break in, if you DO have measurable, documented proof please share it with us.

4. Suspend cables from ceiling using fishing line and eye hooks to escape vibration and static electric fields.

My favorite suggestion!!!  Its right up there with Machina Dyanamica's Intellegent Box, not to mention the Teleportation Tweek!

5. Apply the contact enhancer of your choice to all electrical contacts.

Why?  cables  come with gold connectors for a reason!

Oh ooh, @azbrd where have you been hiding?
Geoff, I think I need a refresher, skeptic or pseudo skeptic?

To one of your points, I did a very small amount of sleuthing and could not find much reported about a positive effect/correlation between cryogenic treatment of copper and electrical resistivity (of course all audiophiles with worthy systems and good ears can hear the difference). There is quite a bit about the effect on ferrous metals used in the cutting industry, and I did read one source that cited a “reduction in grain size” - maybe I need to look further

@azbrd   Have you ever installed new cables in a system and listened over a few weeks as the sound opens up with more dynamic swing?  Regarding not using any type of contact enhancer, you might reference the Perfect Path Technologies "Total Contact" contact enhancer.  I haven't used it but the vast testimonials of those who have point to its efficacy.
