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. Each of our Referenz AIR mains cables is tested and inspected with the utmost care. The results are documented, and each cable is given an individual serial number.

A hi-fi system basically reproduces nothing other than modulated household electricity. This means this should arrive at the device as constantly as possible. Here the mains cable (power cable) plays a significant role. The big challenge for power supply cables is extreme current peaks. They are caused by the connected devices themselves converting alternating current into direct current. These extreme current peaks cause a whole range of undesirable effects. Specially designed for connecting up top-notch high-end audio systems, the Referenz AC-2405 AIR mains power cable is based on the already legendary AIR technology. In conjunction with this technology, i.e. the "omission" of insulation material, which would "soak up" part of the energy like a sponge, the Referenz AC-2405 AIR is able to transport very large amounts of energy in a very short time. Many design details of the Referenz AC-2405 AIR counteract the undesirable effects and make it an outstanding energy pipeline for the highest audiophile requirements. However much we focus on high-end sound, safety plays a particularly important role in this cable category. For this reason, every Referenz AC-2405 AIR cable is tested extremely carefully. In addition to an exhaustive functional test, each cable is also subjected to an insulation and high-voltage test. The results are documented, and each cable is given an individual serial number.

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

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.

Excellent sound starts with the power supply – and this is exactly where the AC-3200 power strip with integrated DC blocker comes in. It filters disturbing direct current components (DC offset) from the power grid, ensuring a symmetrical voltage supply. Ring core transformers benefit especially from this: humming noises are effectively prevented, efficiency increases, and distortion decreases. The DC blocker technology also protects the transformers from magnetic saturation – a condition that not only causes noise but also costs power and can impair sound quality. The AC-3200 was fully developed in-house – from the initial concept through prototypes to the finished product. It is manufactured in our own workshop. Inside, massive copper busbars and high-quality sockets ensure stable conductivity and reliable power distribution. The brushed aluminum housing protects the technology and represents durable quality. An integrated surge protector provides additional safety for your hi-fi components. Each AC-3200 is individually tested – with CE-compliant high-current protective conductor testing and high-voltage insulation measurement. This ensures that every power strip meets the highest technical standards – for reliable operation and long-lasting sound quality. Note on the variants: The AC-3200 DC blocker is available in three versions: DC-15, DC-30, and DC-45. All three versions are designed for a maximum socket power of 3680 watts. For medium and large high-end systems where more punch and dynamics are required, we recommend the DC-30 or DC-45 variants with two or three times the capacity. This provides the right solution for every setup – from compact systems to powerful hi-fi systems. Click here to discover exciting details

The AC-3200 power strip with filter type I was specially developed for analog hi-fi components – such as amplifiers, preamps, or turntables. At its core is a carefully tuned, series-wired filter network that routes power through high-performance coils. These coils offer targeted high resistance to power line interference and effectively reduce disturbances from switching power supplies, household appliances, or industrial equipment. Especially in modern power grids – increasingly affected by digital devices, EV charging stations, or photovoltaic systems – such a filter can make a crucial difference. Although many hi-fi devices have their own power supplies and protective circuits, not all interferences are fully eliminated. Residual noise can still affect the audio signal and reduce sound quality. With the AC-3200, your analog components receive a noticeably more stable and interference-free power supply – for a quieter soundstage, more precise detail, and overall enhanced musicality. The AC-3200 was developed entirely in-house – from the first concept to full production readiness. It is manufactured in our own workshop. Massive copper busbars, durable sockets, and a protective aluminum housing ensure low-loss power distribution and long-term reliability. An integrated surge protector adds extra safety for your system. Each AC-3200 undergoes CE-compliant individual testing – including high-current protective conductor testing and high-voltage insulation measurement. This ensures that every unit delivers exactly what you expect: clean power for uncompromising musical enjoyment. Click here to discover exciting details

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

The air helix design of the Referenz USB-2405 AIR is entirely unique. We’ve developed a special clip to achieve practically perfect air insulation. Inside the cable, in the right numbers these clips form a supporting structure that keeps the helically-arranged signal conductors apart in the air, and guides them through the high-density shielding at a specific distance from each other. The flexibility of this structure is ensured with two struts, which both hold the clips together and fix them at an exact distance from each other. In the proper sense of the word, “digital” only exists in mathematics in the form of the binary number system. There are no purely digital signals in the technical world. Electrical voltage limits and time windows are defined to detect zeros and ones. The jump from a zero to a one or vice versa always requires a certain time, during which the signal level passes through all intermediate values, from 0 volts to 5 volts, for example. Capacitive loads, dielectric losses, noise and electromagnetic interferences caused by cables additionally manipulate this change. This results in temporal shifts, or the, “jitter effect”, which makes precise reconstruction of the audio signal difficult or almost impossible. New 180° USB connector: As we know, USB connectors can only be inserted in one direction. This can be difficult, as the position of the USB sockets in devices varies. To adjust the course of the cable, it often has to be twisted quite a lot, which puts strain on cables, connectors and sockets and also looks unsightly. Our recently developed USB connectors with 180° rotation mechanism offer a solution: Each one can be rotated by +/- 45 degrees, enabling a total rotation of +/- 90 degrees from connector to connector, thus providing the finishing touch for perfect cabling. The dense shielding of the Referenz USB-2405 AIR cable protects the sensitive signal from electromagnetic interferences. Under the shielding is the innovative air helix structure, where air and the spacing between the conductors act as insulators, preventing dielectric losses and significantly reducing capacitive loads. On the whole this makes the digital-to-analog converter’s (DAC) work easier and perfects the audio signal’s reconstruction.
