High End Audio Cables

The RCA and XLR outputs on hi-fi components transmit very weak signals and are therefore highly sensitive to a cable’s electrical properties—particularly its capacitance. High cable capacitance acts like a low-pass filter: it attenuates high frequencies and causes phase shifts that degrade the musical reproduction. Micro AIR technology consistently reduces capacitance, thereby preserving the integrity of the audio signal—for unadulterated reproduction across the entire frequency spectrum, from powerful bass to the finest high-frequency details. Another critical factor is signal noise within the conductor structure. Uncontrolled contact points between the individual wires can generate micro-distortions that manifest sonically as an unpleasant “hissing” sound during S-sounds, among other things. The specially developed Guided Copper construction of the NF-404 specifically addresses this problem: The individual conductors are precisely separated and insulated from one another by PE wires. This ensures a defined structure and a consistent, low-loss signal flow. The symmetrical architecture of the NF-404 Micro AIR also offers high immunity to electromagnetic interference. In environments with numerous potential sources of interference, such as switching power supplies, Wi-Fi, or cellular networks, stray signals are effectively compensated for. The result is stable, low-interference transmission. Whether used on its own or in combination with the LS-404 speaker cable, the NF-404 Micro AIR unlocks the full sound potential of your system and delivers an open, precise, and detailed sound.

Soundscapes are created by the dynamics in the music. To exploit the full potential of your high-end audio components, you need a reliable power pipeline that provides your components with the power peaks with as little delay and loss as possible. This is where the AC-1205 AIR mains connection cable comes into play. Our innovative AIR technology has already caused a sensation in the high-end scene and now also forms the architectural basis for the AC-1205 AIR mains cable. Using specially developed clips, the individual conductors are held at fixed distances and insulated from each other by an "air dielectric". This reduces both capacitive and inductive interference and ensures a smooth flow of energy. The multicore design of the AC-1205 AIR neutralizes the magnetic interference and magnetic fields generated by current peaks and minimizes the line inductance. In addition, the large number of individual wires reduces the skin effect that occurs at high frequencies. Splitting the current across many cores not only increases the usable conductor cross-section, but also increases the overall cross-section of the cable. The result is a reliable power supply, even in the most demanding passages, which allows your sound system to develop its full potential. To minimize electromagnetic interference fields, the AIR cables are shielded with a dense braid of tinned copper. This not only protects your audio components, but also neighboring cables from unwanted interference caused by the high current peaks in the power cable. The in-akustik High End AC-1205 AIR mains cable is an outstanding energy pipeline for perfect audiophile sounds. It eliminates unwanted effects and makes a not insignificant contribution to the most authentic music reproduction possible. Click here and discover the exciting details

Dynamic music places an impulsive load on the output stages of an audiophile hi-fi chain. That's why we developed the Referenz AC-4005 AIR mains cable. Specially developed clips are used to keep the individual wires at a defined distance apart. The resulting "air dielectric" reduces power losses to a minimum and significantly improves the electrical parameters. The multicore structure leads to an overlap, so compensating for the magnetic fields around the individual cores. The line inductance is greatly minimized, depending on the number of cores, and the skin effect caused by steep current flanks at high frequencies is clearly and audibly reduced. In addition, the usable conductor cross-section is effectively extended, and without the negative effects of thicker cables. A dense shielding braid of tinned copper protects neighboring cables and components against external interference and also prevents oxidation.

A stable, low-noise power supply is essential for high-quality music reproduction. Even modern hi-fi components with sophisticated power supplies and built-in filter stages are not entirely immune to high-frequency interference. One cause of this is capacitive coupling effects within the devices, which partially bypass the electrical isolation of the power supplies for high-frequency interference. In conjunction with the dynamic power consumption of connected components, balancing currents arise on the interconnect cables. These interfere with the sensitive audio signal and impair the purity and precision of music reproduction. Furthermore, power cables themselves emit electromagnetic interference fields that can affect nearby signal and component lines. Since these interferences have significantly higher levels compared to the very small audio signals, they have a particularly strong influence on signal processing. The Referenz AC-404 Micro AIR addresses these challenges with a cable architecture consistently designed for signal purity. The sophisticated 6-fold multicore architecture ensures exceptionally low-impedance coupling of the connected components across a wide frequency range. This effectively reduces compensation currents and creates the conditions for clean and stable signal transmission. At the same time, the design enables a powerful power supply with a high dynamic reserve — even during dynamic musical passages and high load peaks. The Micro AIR technology with an air dielectric minimizes capacitive losses and supports fast, controlled energy transfer. The result is more precise impulse reproduction and an authentic, dynamic sound presentation. The design is complemented by dual shielding consisting of a braided and foil shield. This reduces the spread of high-frequency interference fields to nearby components and interconnect cables, thereby contributing to a quiet, clean signal environment. The AC-404 Micro AIR enables music reproduction with greater clarity, detail, and dynamics—for a sound that comes as close as possible to the original recording.

The CAT-2405 AIR is a high-end LAN cable designed for connecting audio components in streaming setups. It is based on our specially developed Air Helix construction, which enables low-loss and interference-resistant signal transmission. For this construction, we have designed a special clip that forms a stable supporting framework inside the cable. Several of these clips hold the signal pairs in a helical shape and at a defined distance freely in the air. The entire arrangement runs within a high-density shield. Two connecting bridges keep the clips evenly spaced and at the same time provide the necessary flexibility in the cable structure. Digital signal transmission: In mathematics, digital information is represented as binary values, but technically it is transmitted via analog voltage curves. To distinguish between states such as "0" and "1", voltage thresholds and time windows are defined. The transition between these states does not occur abruptly, but continuously—the signal passes through intermediate values, for example, between 0 and 5 volts. Capacitive loads, dielectric losses, noise, and external electromagnetic influences can distort these transitions. This results in timing shifts in the signal, known as jitter. Jitter makes it harder to assign data precisely in time and impairs the reconstruction of digital audio signals. Advantages of the Air Helix construction: The overall shielding made of dense braid, as well as additional foil shields for each pair of wires, effectively protect against external interference. The Air Helix construction uses air as a dielectric and ensures a constant distance between the wire pairs. This arrangement reduces crosstalk and capacitive losses, contributing to unadulterated signal transmission. Streaming components and integrated digital-to-analog converters (DACs) benefit from the improved signal quality and can process data more precisely. CAT connector with rotation mechanism: Conventional RJ45 connectors can only be plugged in at a fixed orientation. Depending on the position of the socket, this can result in unfavorable cable routing and mechanical stress on the connector, cable, and socket. To counteract this, we use rotatable RJ45 connectors with a 180° mechanism. Each connector can be rotated by about ±45°, resulting in a total adjustability of about ±90° between both connectors. This allows the cable to be routed without tension and in a space-saving manner. Sound Advantages at a Glance: Air Helix construction: Signal pairs arranged helically in air—minimal capacitive losses Air as dielectric: Reduces crosstalk and improves signal purity High-density shielding (tinned): Overall and pair shielding against electromagnetic interference RJ45 connector with 180° rotation mechanism: Flexible, tension-free cable routing Optimized for high-end streaming: Supports precise clocking in digital audio transmission Conductor material: High-purity OFC copper for stable, low-loss transmission Technical specification: CAT 8.1—up to 2000 MHz bandwidth Made in Germany: Development, manufacturing, and quality assurance on site Click here to discover exciting details
