We cannot defy the laws of physics, but we can use them intelligently. Every audio cable generates parasitic effects, such as capacitance, which stores energy and delays the signal. Air is the ideal dielectric, as it minimizes capacitance. The diamond-shaped structure of MICRO AIR technology maximizes conductor spacing and air content, reducing losses for optimal signal transmission.
The LS-404 Micro AIR is a further installment in the success story of the Micro AIR technology: As with the already legendary AIR Helix cables, air is also a central component of the insulation concept in the Referenz Micro AIR technology. Due to the low speaker impedances, however, low line resistances and a low inductance are also very important for speaker cables. For this reason, the Referenz LS-404 Micro AIR uses a total of 8 concentric copper conductors in addition to the air dielectric. Thanks to this multicore architecture, the magnetic fields of the positive and negative conductors overlap and neutralize each other. This significantly reduces the inductance of the cable, which guarantees unaltered transmission of the audio signal over a broad frequency spectrum. Due to our approach, the LS-404 has an extremely balanced sound character with precise timing, on top of a solidly controlled foundation. This cable is primarily designed for full-size floorstanding loudspeakers. The impression sound makes on the listener is always subjective, of course, and depends in no small part on the overall constellation of a hi-fi system. In the end, the decisive factor is your own personal listening impression. Click here and discover the exciting details
The new Referenz Micro AIR series is a further installment in the success story of the Micro AIR technology: As with the already legendary AIR Helix cables, air is also a central component of the insulation concept in the new Referenz Micro AIR technology. Due to the low speaker impedances, however, low line resistances and a low inductance are also very important for speaker cables. For this reason, the Referenz LS-204 XL Micro AIR uses a total of 6 concentric copper conductors in addition to the air dielectric. Thanks to this multicore architecture, the magnetic fields of the positive and negative conductors overlap and neutralize each other. This significantly reduces the inductance of the cable, which guarantees unaltered transmission of the audio signal over a broad frequency spectrum. Due to our approach, the LS-204 XL has a balanced sound character with precise timing, on top of a solidly controlled foundation. This cable is primarily designed for full-size floorstanding speakers. Sound, of course, is always subjective and depends not least on the overall constellation of a hi-fi system.

Like the flagship model, the LS-204 is also based on Micro Air technology. The difference lies in the multicore architecture. Compared to the XL version, the LS-204 has four instead of six Concentric Copper conductors. This cable boasts an agile character and was primarily developed for slim floorstanding speakers with smaller bass drivers. The Referenz LS-204 Micro AIR is available as a single-wire version with BFA bananas or spade lugs, or as an Easy Plug version. Click here and discover the exciting details
The LS-104 is an excellent entry-level model to the Micro AIR series. It already stands out clearly from standard cables and demonstrates the acoustic potential of this technology. Sensitive amplifiers in particular harmonize excellently with this cable. The Referenz LS-104 Micro AIR provides an open and relaxed sound. It is also available with BFA bananas or spade lugs and as an Easy Plug version. Click here and discover the exciting details
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.

Because the outputs on hi-fi devices only supply extremely weak signals and are sensitive to high cable capacitance, the capacitance of a cable plays a significant role when connecting components together. A “low-pass filter” can be created that cuts off high frequencies and also causes phase shifts. This is the reason why RCA and XLR audio cables are ideal companions for the air-based insulation used in the MICRO AIR technology. Another special feature of the NF-204 Micro AIR is its symmetrical architecture, which guarantees high immunity to EMC radiation. Alone or in combination with the LS-204/LS-204-XL, the NF-204 Micro AIR opens up the connection floodgates and allows your components to perform at their very best.

Another special feature of the NF-204 Micro AIR is its symmetrical architecture, which guarantees high immunity to EMC radiation. In addition to this, we have also developed a completely new and entirely solder-free RCA connector for the Micro AIR series. It consists of several component parts that are only joined together during course of the assembly process. The cable ends are prepared in our cable manufacturing unit, with meticulous care and a passionate attention to detail. They are then inserted into contact pins made of tellurium copper and pressure-grouted using a force of 1.5 tonnes.

Compared to the NF-204 Micro AIR, the NF-104 Micro AIR has a conventional, coaxial architecture. In addition to the Micro AIR technology, another special feature of the NF-104 is the newly developed RCA connector, which is completely solder-free. Omitting the solder significantly reduces transition resistance and element formation. As the name suggests, the NF-104 harmonizes particularly well with the LS-104 speaker cable. Both cables are the perfect way of entering the world of Micro AIR technology. 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.
