Cryongenically treated in-wall AC power wire


I have a high end sound system and am building a new house.  I would like to have a dedicated electrical line installed for my system, to run from the electrical outlets in my music room to the breaker box.  The builder asked me how long I wanted the wire to be, which runs from the outlets to the breaker box.  I have no idea.  I could place it as close as several feet or much longer.  The wire is $20/foot.  So, here are my questions:

1.  If you want to install a dedicated electrical line for your sound system how close should the electrical outlets be to the breaker box, or does it make a difference?  In other words, is there a minimum length of cryogenically treated wire that I will want in the wall stretching from the outlets to the fuse box?

2.  I assume that using cryogenically treated wire and electrical outlets will reduce noise.  Does anyone have any experience with cryogenically treated wire?

A separate electrical meter and utility line feeding it from the street, running to its own breaker box and the dedicated wiring fed from there. Full isolation from the electrical system powering the rest of the house.

Local zoning will often prohibit such an arrangement, because it could allow a multi-family home (or home with a separate business) in what might be a neighborhood limited by zoning to single-family homes. In any event - even where it would be permitted - the grounding system would almost certainly need to be common between the two systems in order to comply with NEC.

Again, the solution to the perceived problem of "noisy grounds" on an audio system is not to pursue multiple grounds, but to ensure that all the grounds are clean. And the neutrals. And the hot connections. Noise can be introduced anywhere in an electric system, not just the ground.

The link that almarg previously provided is an authoritative resource that slays many grounding myths. Here’s one of them:

" Its connection to earth is not what makes ’safety ground’ safe ... its the connection to neutral. "

That’s worth pondering as you consider that NEC requires neutral and ground to be bonded together at the service panel.






For my 2c's on a very complicated subject is this;

1. Run the best ac cable you can afford. (10 gauge)
2. Run at least 3 dedicated lines
3. Space each line at least 1"+ from each other.
4. Use the best outlets you can afford. (Furutech GTX Nano etc)

All of this is the backbone to your present system and all future equipment changes will benefit.

Ozzy, what components would you connect to each of the 3 dedicated lines?  If you have a power conditioner does it make any difference?

gapperis123,

I have my digital, analog and subwoofers on the separate dedicated lines. At the wall, I installed quad boxes (Oyaide) with dual Furutech GTX nano outlets in each quad.

I have a CPT 1800 balanced power on the analog. I have a CPT 300 on the digital. And the subs (JL F-113’s) on the third dedicated line.

The sub line was also routed to the back of my room so additional subs are plugged into that quad outlets.
Any extra unused outlets have multiple SR MC-05’s plugged into them. A total of about 20.

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.
