"All the noise from electrical appliances and shielding (even from neighbors) are dumped into the thin high resistance ground wires of the house. The noise will build up like a traffic jam so that the grounding speed will slow down."

If homes in Sweden are wired with "thin, high resistance ground wires", you are as good as dead should an electrical accident occur. Highly resistive ground paths are used to prevent breaker trips in hospitals and other critical applications where you want to be alerted to a ground fault, but not have the equipment power down as a result.

If the ground path is highly resistive, the path through your body would be the least resistent. Touch anything with a grounded chassis and kiss your keester goodbye...

When I used PS Audio Premier Power Plant together with Virtual Dynamics Genesis power cables, touching the brass clamps surrounding the cable resulted in an electric shock. The Premier Power Plant was dumping noise into the ground which was circulating in my system, I have owned two Premier with the same problem. I have owned three P300 Power Plants without this problem, but they sounded very blurry and slow, they just toned down the brightness to make it more relaxing to listen.

Now I have switched to GroundHanger without any weaknesses. I can touch my system all over the place without any danger of electric shocks like with other power conditioners that operate on AC power.
Instead of toning down the brightness, GroundHanger removes harshness which makes it sound both clearer and silkier. Coconut-Audio tweaks were built for maximum microdetail without coloring the sound. The microdetails are very quick and clean. Midrange is transparent and lifelike. GroundHanger replaced all power conditioners I have owned, and it's very small and portable.

The ground wires in Sweden are about 18 awg. We have compared 1 awg vs 00 awg with very noticeable improvements, and this was with just 30cm long wiring! You would need many tons of copper to do house grounding properly, you would need the walls to be pure copper to maximize area and lower the resistance.

Instead of building a copper house, just move the ground closer to the component instead. This is why GroundHanger hangs directly from the RCA as close as possible to the noise that needs to be grounded.

"The ground wires in Sweden are about 18 awg."

18AWG wire is the minimum you will find on a standard table lamp with a max bulb rating of 60 watts here in the U.S. If what you say is true, I'd be concerned.

"You would need many tons of copper to do house grounding properly, you would need the walls to be pure copper to maximize area and lower the resistance."

WHAT? How much lower do you think the resistance can go? The ground wiring in a home is there as a safety device. It is not there to shield the home from outside interferences. You are truly "coconuts". But that was evident when you asked about spending a couple of days in a cryo chamber, where to find a suit to do so, and how you would be able to consume water while in the chamber.

Your web site, press releases and price-cut/cryo chamber posts have provided some amusing reading, but nothing more. Best of luck in your pursuit of silkiness, microdetail, transparency, bass texture, and finding customers who are willing to pay the price...

Audio components aren't perfect because they generate RFI/EMI into the air. If the metal chassis is closed it reflects back the noise into the motherboard and interferes with the audio signal. There's a lot of noise reflecting back and forth inside the case and in the motherboard. The house ground wiring isn't good enough to remove this noise, you need something more powerful with lower resistance. This is why GroundHanger was born. The scattered RFI inside the chassis will enter the GroundHanger where it's cleaned. This gives a noise free motherboard and clearer audio signal.

Have you measured this noise, or are you merely hypothesizing? For someone with a questionable scientific background you make some pretty hefty claims. And those include your ability to hear differences in glues and 1/100th of a gram of "material".

I have measured this with my ears. 5 years ago I did a lot of experimentation with ERS Paper, see video: http://www.youtube.com/watch?v=deW6WPq-d00

After I covered the inside of the chassis with ERS Paper I got a drier sound, I didn't like it at first so it definitely made a difference, I wanted to remove it but couldn't because I used ERS with adhesive backing in some places. After a while I got used to the sound and it sounded good. The transients were hairier and there was more resolution. To compensate for the warmer/greyer sound I disconnected conductors from Nordost Valhalla cables to make it brighter and edgier, I used only 1 conductor from the Litz wire, it increased microdetail and blackness. But the problem was that multiple colorations were added to the system which I had to compensate for by adding other tweaks, it never stopped and I was never satisfied with the sound.

Now I use stock cables and no tweaks other than Coconut-Audio, and I get better sound than ever. It's perfecty synergized too because there are no colored devices in the system.

I have no time to view another, what I can only expect to be, agonizingly slow and confusing video. Must be nice having golden ears. But no matter how good your hearing is, you will never be able to "measure" anything with your hearing. You can only perceive a change. There is nothing quantifiable about hearing, unless it gets tested by an audiologist. And rest assured that your hearing is not sensitive enough to hear a difference when glue accidentally makes it's way to a cable sheath.
