The best cable isn't the one that squeezes the most out of your hi-fi setup, but the one that loses the least of the original sound. Cables should just sound natural and stay out of the way.\"\u003c\/em\u003e — Holger Wachsmann, Product Developer, in-akustik\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis is the philosophy behind the Referenz NF-404 Micro AIR — and it is a more demanding ambition than it might initially appear. An interconnect cable that truly stays out of the way must overcome capacitance, signal noise, and electromagnetic interference without adding any character of its own. The NF-404 Micro AIR addresses all three with dedicated engineering solutions, and does so in a cable designed and manufactured by hand in in-akustik's own factory in Germany.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe result is an open, precise, and detailed sound — not because the NF-404 adds anything, but because it removes the obstacles that stand between the recording and the listener.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eThe Problem: Capacitance and Its Consequences\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe RCA and XLR outputs of hi-fi components transmit very weak signals — and those signals are acutely sensitive to a cable's electrical properties, particularly its capacitance. Every cable stores electrical energy in its dielectric insulation material and releases it again with a time delay — acting, in effect, like a battery that absorbs part of the audio signal and then discharges it slightly late.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis is not a subtle phenomenon. High cable capacitance acts like a low-pass filter — attenuating high frequencies, introducing phase shifts, and degrading the precision of transient reproduction across the entire frequency spectrum. The result is a cable that makes the system sound slightly rolled-off, slightly smeared, and slightly less alive than the recording actually is.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTo understand why, consider what happens when you take off a synthetic sweater: the crackling sound you hear is electrical energy stored in the plastic being discharged. The same thing happens in the dielectric of an audio cable — the material absorbs part of the signal like a sponge and then releases it. The ideal dielectric is one that doesn't store energy at all. That material is air.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eMicro AIR Technology — Air as the Dielectric\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe laws of physics cannot be switched off. But they can be used as ingeniously as possible. In-akustik's Micro AIR technology uses a complex, diamond-shaped insulation structure — a precision geometry that creates tiny air chambers between the conductors. These chambers increase the distance between the conductors, raise the proportion of air in the insulation, and dramatically reduce the cable's capacitance compared to any solid dielectric material.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe NF-404 Micro AIR follows directly in the tradition of in-akustik's acclaimed Referenz AIR Helix cables — applying the same fundamental principles of air-dielectric design in a more compact, versatile form that is equally at home in an entry-level audiophile system or a reference installation.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eGuided Copper — A Defined Architecture for a Defined Signal\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eConventional cable conductors arrange their individual wires in a loosely controlled bundle — and where wires are in unpredictable contact with one another, micro-distortions occur. These uncontrolled contact points generate signal noise that manifests sonically as an unpleasant harshness in sibilant sounds (\"S\" sounds in vocals are a common tell), a veiling of fine high-frequency detail, and a degradation of spatial imaging.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe NF-404 Micro AIR's Guided Copper construction eliminates this problem entirely. At the centre of each conductor is a PE wire around which the OFC copper wires are arranged in a precisely defined geometry. Additional PE wires separate and insulate each copper wire from its neighbours. Every contact point is controlled. Every wire is in its designated position. The result is a stable, uniform signal path in which interference and noise are significantly minimised — preserving fine details, improving clarity, and delivering signals with the precise timing that underlies convincing spatial imaging and transparency.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe copper itself is high-purity OFC (Oxygen-Free Copper) — chosen for its excellent conductivity and high signal fidelity.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eSymmetrical Architecture — EMI Immunity\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe NF-404 Micro AIR's symmetrical signal architecture provides high immunity to electromagnetic interference — the switching power supplies, Wi-Fi routers, mobile networks, and other EMI sources that pervade modern listening environments. Stray signals that enter the cable are effectively compensated for by the balanced layout, producing stable, low-interference transmission regardless of the electromagnetic environment.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis makes the NF-404 Micro AIR a reliable choice not only in dedicated listening rooms, but in any real-world system installation where interference cannot be controlled.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eMade in Germany — Manufactured by Hand\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eEvery NF-404 Micro AIR cable is manufactured by hand in in-akustik's own factory in Germany — a process that includes complex manual assembly, functional testing, mechanical testing, and live performance verification before any cable leaves the factory.
