”By human hands for human ears” This is our motto. Within it lay the Sonus Concordia philosophy.
Sonus is Latin for sound and Concordia was the ancient Roman goddess of harmony and unison.
We don’t design cables in a computer and think within ”the box”, because then our cables would be the same as everybody else’s.
We have 25 years of knowledge of how different materials and geometries interact and how it translates into a musical experience. We don’t worry about problems that don’t really matter for the musical performance, Rather, we build cables that sound good, organic and non fatiguing, with air, details, dynamics and every nuance of music in a passionate presentation.

There are many ways to achieve good sound. Cables matters and they can surely make or break a system.
Our goal is to make cables that don’t rob music of its essence.

The way we see it, a component cannot add anything to a music signal, just take away something. This is not entirely truth though. All kinds of distortion adds something, and static as well as charging and discharging dielectrics add something to the signal. It also robs something from the music signal.

Some materials are more prone to these negative effects, especially many types of plastics. Different types of plastic, Teflon and PE for example are surely better than say PVC. Therefore we use them instead, where we must. For all signals we use cotton as dielectric and isolation. Cotton is unique in its low dielectric constant. The dielectric constant is the capability of a material to absorb and discharge energy, low numbers are good, high numbers absorb more energy and release it more slow, which in a music signal is bad.
The dielectric constant is measured on a scale where vacuum is 0, AIR 1, PTFEE, Teflon and PE are 2,3 and PVC 4-8, cotton however is just 1,3!! This means, almost as good as air.
Another good properity of cotton is its ability to absorb vibration and reduce resonance.
The problem is that cotton absorbs moisture and therefore must be contained in some sort of barrier against the different humidity of surrounding air.
We use a high grade Polyolefin for this task. It’s gas tight, it’s flexible and not very expensive. It also has a low dielectric constant level.

Another important design feature is the solid core principle. In our study, solid core designs offer better sound than multi strand. Why is that?
One theory is the so called diode effect. Small charges between the strands when electrons change strand and skips over to a nearby strand resulting in a small discharge that interrupts the music signal and adds a sort of distortion. Some say that this effect is too small for the human ear to detect. If so, why do so many people prefer solid core?
We believe that a human can hear it but different individuals are more sensitive to this effect. The diode effect seems to enhance high frequencies and add a sense of detail. The downside, however, is that it also makes music more fatiguing in the long run. It sounds different to different individuals and some even like it.

A signal that travels along a piece of wire actually moves forth and back along with the music signal. It’s a chaos of different waves in all frequencies while the other lead is the ground plane, the solid reference for the music signal. These two are equally important factors for the sonic results. We use different geometrical designs to master the reactive forces of inductance, capacitance and resistance, thereby increasing the sonic performance. The different gauge of wire used is another step to control skin effect and resonance.
It also helps to avoid the EMI and eddy currents due to the proximity effect.

A shield is a double sided sword, There are some benefits and in some applications it is necessary.
What is wrong with a shield, you might ask?
Well for one thing it ads a lot to capacity and that’s not a desirable effect when it comes to signals. The internal noise and electromagnetic fields within the cable are influenced and the sound becomes restrained.
For very weak signals like in a turntable setup, we think that shielding makes more sense, or actually is necessary.
When there is no problem however, a shield is like eating aspirin for prevention, just in case you might risk getting a headache.

Ok so the way to good sounding cables are:
Solid core in a good dielectric, preferably air arranged in a geometry that allows for a compromise between the reactive forces in the most beneficial way. Easy as 3.14159265359 right!
