The concept of the Sternklang cable is "maximizing the rate of energy metabolism" or "minimizing the load on the cable conductor (cable wire)".
We believe that the sound quality of audio cable is determined by the balance between the "vibration characteristics" of the conductor and the "load" that is applied the surface of the conductor per unit area .
The "load" is generated by the mass of the insulator and the tightening pressure from the insulator on the conductor.
There are three roles of the insulator, to insulate, to stop the resonance of the conductor, and not to transmit external vibration to the conductor.
The amount of load required to stop the resonance of a conductor is proportional to the multiplication of the "elastic modulus" and "mass" of the conductor.
The "elastic modulus" is determined by the "material and cross-sectional shape" of the conductor.
From our experience, we have drawn the following conclusions.
Conductors that require a only "littel" load to stop resonance have a lively sound. And the attenuation of high frequency signals with small amplitude (rich in spatial informations) is reduced.
In addition, the idea of "an insulator that does not transmit external vibration to a conductor" actually produces the opposite effect. The cable made with this idea actually imprisons the energy of external vibration into the cable and chokes the music.
Therefore, our cable eliminates the idea of "an insulator that does not transmit external vibration to a conductor".
The conductor of the Ephemera series is a copper foil with a thickness of 0.035 mm and a width of 7 mm. Compared to round wires with the same cross-sectional area, it has eight times the surface area and extremely small elasticity. Therefore, the load to per unit area required to stop the resonance of the conductor is 1/8 or less of the round wire.
The Sarume series introduced the concept of Ephemera into a coaxial geometry that is resistant to disturbance noise, and challenged the limit of “energy metabolic rate" as a cable that uses a round strand. An alloy of silver and gold with low elasticity is used for the conductor.
It seems to us that a wire of audio cable is not a solid body but a living organism in which numerous cells breathe. Each cell has it’s own vibration damping function and they all cooperate with each other. So numerous cells should not be suffocated with insulators.
Your audio system, which you are familiar with, will do its best with the Sternklang cables. That is our wish.
