These cables surely got my attention. As it seems sourced from the German copper minds and made strictly to In akustik specs, Reference selection high end audio cables are something worthy of exploring...
The transmission of acoustic signals is susceptible to any different types of interference: resistance, inductance, capacitance, conductance of the insulation and skin effect have a negative influence on the sound. The conductor material is also very significant. Because every contamination in the conductor material prevents the flow of current, impairing the conductance and increasing the background noise. That's why we use only especially pure, oxygen-free copper (OFC) with a high conductance in our Reference cables.
Cables and connections are extremely sensitive. Physical phenomena that arise during the transmission of signals can only be controlled with technical finesse and the best materials. For this reason all cables are manufactured in a German cable mill and finished by us in Ballrechten-Dottingen in elaborate manual work.
PERFECT SOUND BEGINS IN THE MINE
It starts somewhere in the world in one of the mines in which copper ore is mined. From there the material is delivered to Germany, liquefied in melting pots in copper smelting plants in northern Germany.
In order to create the purest possible, most conductive copper, the valuable raw material must first be placed in an electrolysis bath.
For Referenz Selection, only select, highly pure batches are used. Only after this pure material is found in elaborate processes is the copper drawn to the required diameter in several stages fter that it is stranded with air-filled PE tubes in a German cable plant
How do you tease out the last bit of quality from the components?
"No idea is too crazy for us in this regard. But we have so far always had the best experience with development based on the fundamentals of electrical engineering and physics. We can now make very good predictions of the sound direction in which a cable will go.
The first phase of development involves unfettered drafting, brainstorming and calculating. Ideas are sometimes discarded and reconceived until detailed technical drawings can be created from the designs. For development and implementation, it is very helpful that our company group has its own cable mill at its disposal. In our in-house finishing plant, we can also build and perfect prototypes."

PRODUCTS
We at in-akustik are pioneers in perfect signal transmission, helping to convey the finest nuances that appeal to all senses. We put passion, ambition and love into the development and production of our cables, which are known throughout the world for outstanding quality. The ultimate proof for this is Reference Selection. Dynamics, power and precision cannot be more clearly sensed with any other product range. That's why these cables are only available in select specialized stores.
COPPER
The transmission of acoustic signals is susceptible to any different types of interference: resistance, inductance, capacitance, conductance of the insulation and skin effect have a negative influence on the sound. The conductor material is also very significant. Because every contamination in the conductor material prevents the flow of current, impairing the conductance and increasing the background noise. That's why we use only especially pure, oxygen-free copper (OFC) with a high conductance in our Reference cables.
PE NETWORK JACKET
Every additional material used has negative influences on the signal transmission. Many cables have a subcoating between the coat braid and the wires, made of PVC for instance, which has an unfavorable impact on the electrical parameters. In contrast, the wires of Reference cables are directly braided with a PE network jacket. The cables consist of two materials: copper and polyethylene. The PE network jacket consists of monofilaments that hold the wires together tightly. This reduces micro-vibrations and facilitates the clean conversion of extreme dynamic peaks.
DUO-PE II INSULATION
Theoretically, air is the best insulator, and polyethylene is also excellent in practice. For Reference cables, in-akustik developed insulation consisting of two layers of polyethylene. The first layer is foamed with air. A second, solid PE sheath is applied over that. This DUO-PE II insulation prevents high capacitance and eases the work for the electronics.
MULTICORE
The flow of current causes magnetic fields to be created in the cable, leading to a partial loss of power. High frequencies are slowed down - and time lag is created between low and high sound frequencies. The circular arrangement of several wires around the polyethylene support causes the magnetic fields of plus and minus conductors to overlap and neutralise each other. The high sound frequencies are transported unhindered and synchronous
HIGH SPEED WAVEGUIDE
As the frequency rises, the signal increasingly flows on the conductor surface. The higher the frequency, the lower the effective cross-section, and the greater the resistance. The cable sounds "bass-heavy". The conductors from the Reference loudspeaker cable have a core made of polyethylene. In this way a circular waveguide is formed and the actual cross-section used is the same for all sound frequencies. The result: a omogeneous, balanced loudspeaker cable with a wide-ranging sound spectrum.
CONCENTRIC COPPER
In conventional cables, the individual wires are arranged chaotically in the strands. The signals move in a zigzag fashion. The consequence: individual signals are "in transit" for longer than others; high frequencies lose their dynamic. In concentric copper strands, the wires are arranged in several layers around a polyethylene core in the middle. The signals flow more harmonically, impulses are reproduced exactly and the spatial information is retained.
HIGH POWER MANAGEMENT
The tightly fitted PE network jacket holds the wires close together and reduces micro-vibrations that arise in the cable from the changing magnetic fields caused by the beat of the music. The cable therefore also transmits high levels and extreme dynamic peaks with absolute precision.
HIGH SPEED CONDUCTOR
The new generation of Reference NF cables has finely stranded signal wires, with each individual wire having a lacquer coating. This coating insulates the wires from each other, creating a larger effective conductor surface. It also prevents eddy currents between the wires. A conductor that can also pass on extremely dynamic signal sequences very quickly and precisely.
