Hello Gaetano,
Sorry to hear you are having difficulties with a JPS product. We try to please everyone but as you know it is a difficult task.
We have nothing to hide. The UK version of that AC cord does not have a network in the wall plug. The very low quantities required for that country does not allow us to manufacture a custom UK version of that cord, so we do our best with what is available. We did however have a nice heavy gold plate UK wall plug made for it. Had you contacted JPS prior to your purchase we could have told you that these cords are not interchangeable.
Two possibilities are to return the cord in whatever condition it is in for a full refund from Audio Salon, or to use it with your choice of euro plug. It will still be quite effective for your digital front end, just as effective as the UK version if you use a nice Euro plug.
Exhibiting the inside of cables on a website... for you and I being curious engineers it may be ok, but 99.9% of our customers know little about the manufacture of wire and cable, so it would be of little use to them and therefore would not help us to promote JPS. What I do in cable design is a very specialized field of engineering which I had to learn myself during the last 20 years, much understanding of materials and how they relate to sound reproduction had to be learned. The subtle details within the cable and conductors would not be understood nor heard by a picture or specifications- that is my job and is what people ultimately pay for- To listen.
Thank you, Gaetano!
Enjoy the weekend... Joe
In a third email Joe said to me:
Hi Gaetano,
The schuko version is a moulded plug with a network built-in, as is the US version.
Take care... Joe
Dear Joe........sorry........but you look like Berlusconi.
In Italy we had: Leonardo,Galileo,Brunelleschi,Michelangelo and more others.
Now we have:Carlo Rubbia,Rita Levi di Montalcini and others.
But we have Berlusconi,too.
When he answers to the questions,he tells what he wants but nothing about the real questions,such as you have done with me.
You could be a great italian politics or a fine philosopher in the world.
You tell me that "The very low quantities required for that country does not allow us to manufacture a custom UK version of that cord, so we do our best with what is available".
And again:"The schuko version is a moulded plug with a network built-in, as is the US version."
So the UK version isn't a real JPS digital AC!!!!!!
i'm impressed........why on your web site there is written nothing about this?
About this:"Exhibiting the inside of cables on a website... for you and I being curious engineers it may be ok, but 99.9% of our customers know little about the manufacture of wire and cable, so it would be of little use to them and therefore would not help us to promote JPS".
We want to know,for example, if the dielectric is air,teflon,PTFE, or PVC.
We pay much money for your cables and i think that we have the right to know the material......not the secret,the snake oil,of course.
I know that in some cables you use the PVC insulation(Digital AC,Analog AC).
These cables have recieved enthusiastic reviews and they sound very good.
Don't you think that saying that the dielectric is PVC you could subvert the theory that PVC is a cancer for the hi end cables?
An example taken from TNT-audio:
"An aspect that could be relevant is the propagation velocity of the signal through the cable.
This is a physical characteristic of the cable which depends on its electrical parameters. Roughly speaking, it depends on the square root of the inverse of K, the dielectric constant of the insulation of the cable. To name a few examples, PVC insulation has a high dielectricity, hence it causes the velocity propagation to be lower (since it depends on the inverse of K). PE is better than PVC while PTFE/Teflon is better than PE.
This parameter can BE precisely measured in terms of % over the speed of light c. A propagation velocity of 80% c (velocity factor, actually) means the signal transits at 80% of the speed of light (300,000 km/sec). This characteristic varies greatly from one cable to another. For example, PVC allows the signal to travel at 50% of the speed of light, PE at 65.9%, PP at 69%, PTFE (Teflon) at 70% and PE foam at 80%.
The real problem with PVC isn't the delay it adds to the signal. Actually its dielectric constant slightly varies with frequency and hence varies propagation speed. This could be a problem."
However, many cable makers(such as Cardas,Kimber,Audioquest,Shunyata etc etc) put on their web site the tipology of the construction of their cables, photos and dielectric material.....and the cable theory.
Sorry again Joe,
I know that you have a Nissan GT-R......a beautiful expensive car.........a question........and if under the label Nissan there was a film of polyolefin and under this film there was written Volkswagen Golf, and the men who works for Nissan have tried to delete the Volkswagen lebel, what you'd think?
