Inakustik Referenz NF-2405 AIR | XLR 1.5m
Overview
The Inakustik NF-2405 AIR XLR analog audio cable is the result of expertise in audio engineering. Designed and manufactured in Germany, this cable combines innovative technologies with precision craftsmanship. It ensures high-quality audio signal transmission, delivering faithful and detailed sound reproduction.
The Air Helix Revolution: Air as the Ultimate Insulator
At the heart of the NF-2405 AIR lies the patented Air Helix technology. This innovative approach uses air as the primary dielectric, providing near-perfect insulation for the conductors. Specially designed clips keep the conductors suspended, surrounding them with air along almost their entire length. This method minimizes capacitance and dielectric losses, enabling remarkably fast and precise signal transmission.
Using air as an insulator is not just a technical feat; it brings tangible benefits to sound quality. By reducing interactions between the conductors and traditional insulating materials, the NF-2405 AIR preserves the integrity of the audio signal at an unprecedented level. The result is exceptional sound clarity, precise stereo imaging, and faithful reproduction of the subtlest musical nuances.
The Art of German Craftsmanship
Each NF-2405 AIR cable is a testament to German artisanal excellence. Entirely handmade in Inakustik’s workshops, every step of its production is carried out with meticulous attention to detail. Technicians manually assemble the Air Helix clips, carefully thread the conductors, and apply the shielding and outer sheath with surgical precision.
This artisanal approach not only ensures consistent quality but also allows for rigorous control at every stage of manufacturing. Each cable is meticulously inspected and tested before being approved for sale, ensuring that every NF-2405 AIR meets Inakustik’s exacting standards.
Innovation in Connectors: 180° Rotating XLR
Inakustik has taken innovation beyond the cable itself by developing unique 180° XLR connectors for the NF-2405 AIR. These connectors can rotate ±45 degrees, offering unmatched installation flexibility. This feature elegantly solves the common issue of rigid XLR connectors, which can be difficult to insert in tight spaces or complex equipment setups.
The rotating capability of the connectors also reduces mechanical stress on the cable and device sockets, potentially extending the lifespan of the entire system. Additionally, this flexibility allows for a cleaner and more aesthetic installation, a detail appreciated by audiophiles concerned with the appearance of their setup.
Materials and Construction: The Pursuit of Perfection
The NF-2405 AIR makes no compromises on material quality. The conductors are made of high-purity oxygen-free copper (OFC), chosen for its excellent conductivity properties. The Cross Link Super Speed waveguide used in the cable’s construction is designed to avoid skin effects and ensure uniform signal transmission across the entire audible frequency spectrum.
The cable’s shielding is equally impressive, utilizing a dense, tinned copper braid. This approach provides excellent protection against external electromagnetic interference while preventing long-term oxidation. The outer PE network sheath completes the construction, offering durability and flexibility.
The XLR connectors, beyond their rotating capability, are crafted with the same attention to detail. Their tellurium copper contacts are rhodium-plated, a precious metal chosen for its corrosion resistance and excellent conductivity properties. The connector housing, made of solid metal, ensures a stable connection and effectively protects against interference.
Impact on Sound Quality: Beyond Specifications
While the technical specifications are impressive, the ultimate goal of the NF-2405 AIR is to enhance the listening experience. The combination of Air Helix technology, premium materials, and precision craftsmanship translates into exceptional audio performance.
Users report a noticeable improvement in sound clarity, particularly in the high frequencies. Instrument separation is more precise, allowing for better perception of subtle details in complex recordings. Low frequencies also benefit from this design, gaining definition and impact without overpowering the sound spectrum.
The soundstage is described as wider and deeper, with precise positioning of instruments and vocals. This improvement in stereo imaging contributes to a more immersive and realistic listening experience.

Frequently Asked Questions
Why is air insulation so important in an audio cable?
Air is considered one of the best natural dielectrics. Unlike solid materials, it introduces virtually no distortion or loss in the audio signal. This air insulation minimizes the cable’s capacitance, enabling faster and more precise signal transmission, which translates to better sound quality, particularly noticeable in high frequencies.
How does the NF-2405 AIR differ from standard XLR cables?
The NF-2405 AIR stands out with its patented Air Helix technology, German artisanal craftsmanship, and unique rotating XLR connectors. Unlike standard XLR cables that use solid insulators, the NF-2405 AIR primarily uses air as an insulator, offering superior performance in terms of capacitance and signal preservation.
Is this cable suitable for all audio systems?
The NF-2405 AIR is designed for high-end audio systems where every component is of superior quality. While it can technically be used in any system with XLR connections, its benefits will be more noticeable in setups where the rest of the equipment can reveal the subtle nuances it can transmit. For entry-level or mid-range systems, less expensive alternatives might offer a better cost-performance ratio.
Does the NF-2405 AIR require a break-in period?
While some audiophiles believe in the need for a break-in period for cables, there is no scientific consensus on this subject. The NF-2405 AIR should deliver optimal performance from the first use. However, some users report a slight improvement in sound after several hours of use, which could be attributed to material stabilization or ear adaptation.
Is the NF-2405 AIR compatible with home theater audio systems?
Yes, the NF-2405 AIR can be used in high-end home theater systems equipped with XLR connections. It can be particularly beneficial for critical connections, such as between an audio-video processor and separate power amplifiers. However, for most standard home theater setups, less specialized cables might offer a better value for money.
