Cryongenically treated in-wall AC power wire

A few years back while doing a dedicated room for my audio, I ran across something very interesting. It's not about cryo treated wire, but it is about reducing ground noise. So if that is your ultimate goal ( and cryo is just one way you were trying to achieve that) I urge you to at least check out the video at twisted-power.com.
I learned about this from some manufacturers of precision test equipment for the electronics industry who were exhibiting at CES in the high end audio section. I followed up on it and ended up talking with the developer a number of times. I incorporated the concept in my new room and I now have the quietest system ever. So I do believe it's the real deal and it really is not expensive at all - or difficult.
Oh, and you can use cryo'd wire that you twist according to this technique (well actually there are several specific techniques available to attain the desired effect) if you so desire. 

When connecting the new wire to terminals,  clean the wire and new terminals with a  electrical contact cleaner and if you wish, apply a contact enhancer.  In my experience, Furutech Nano Liquid last the longest of the ones I have tried. 

@craigus, thank you for your post and the very informative link to twisted-power.com. It's always interesting to watch demonstrations made available on websites even if one is aware of the knowledge. I'll keep that website on file for others in the future.
Best regards...

From Whitlock’s paper almarg cites above:

What Does “Ground” Mean

• Also known as “Earth” in the rest of the world

• A FANTASY invented by engineers to simplify their work

• The “uni-potential” fantasy assumes all ground symbols in schematics are at exactly the same voltage

There’s a lot of good information in that article, such as Romex is preferable to conduit for reducing noise, as it keeps the hot and neutral wires in optimal alignment.

 I tried to cryo one of my DIY power cables to see what happens to the sound.
After burning-in, I opted out of cryo treating my reference cables.
It made the sound more lean and dry, less full.
One more note - I found that the longer the power cable is, the more of its "sound" is present in the system. That can be good or bad.
If you have very fast-detailed-silver sounding power cable, 1 meter will influence the sound in that way more than 0.5 m of it.
I would bet that the same applies for the power line in the wall.
I have dedicated power lines in my system (8), and they are on a separate breaker box.
So my apartment has 2 breaker boxes - 1 audio and 1 for everything else.
I kept the wires at minimum required length, which is still several meters.
Each line has electric filter installed before the outlet.

I think the investment in AC pays off in the final sound.
