in-akustik Unveils NF-404 and AC-404 in Reference Micro Air Cable Series

Explore the new NF-404 and AC-404 cables from in-akustik, boosting the Reference Micro Air lineup with cutting-edge design and pristine sound quality.

When it comes to high-fidelity audio, cable quality can often be the unsung hero of your setup. If you’ve ever found yourself obsessing over every little detail in your sound chain, then you’ll appreciate what in-akustik has done with the latest additions to their Reference Micro AIR series. Say hello to the NF-404 Micro AIR interconnect and the AC-404 Micro AIR power cable — two meticulously engineered pieces that bring a fresh breeze to the art of signal and power transfer.

Meet the NF-404 Micro AIR: A New Standard in Interconnects

The NF-404 Micro AIR is designed to connect your analog sources to amplifiers with crystal clarity. What’s exciting here is the use of the proprietary Micro AIR technology combined with a fresh conductor architecture crafted from oxygen-free copper (OFC). This isn't just any copper — it’s pure, stripped of oxygen to ensure that signal degradation is kept at bay.

Imagine the conductors nestled inside polyethylene spacers — this geometry isn’t just for looks, it physically reduces interference between the strands, keeping the noise floor low and the signal crisp. The cable sports a fully symmetrical build and features double shielding to fend off any pesky electromagnetic or radio frequency interference. Whether you prefer RCA or XLR connectors, the NF-404 offers both in lengths ranging from 0.75 to 2 meters, fitting neatly into various setups.

The sleek Reference Micro AIR cables blend engineering precision with high-end audio aesthetics.

Power Up with the AC-404 Micro AIR Power Cable

Switching gears to power delivery, the AC-404 Micro AIR is tailored to keep your system fed with clean, stable energy. Borrowing much of the same engineering magic from its interconnect sibling, this cable features a six-wire design boasting low resistance, which minimizes electrical cross-talk between connected components.

Power cables often sneak under the radar, but the AC-404 commands attention with its double shielding and Micro AIR technology, effectively reducing parasitic capacitance and combating high-frequency noise. It’s a serious step up for anyone who’s experienced the subtle yet noticeable hums or interference that less refined power cables can introduce.

The AC-404 comes equipped with a variety of plugs — SCHUKO-C15, SCHUKO-C19, NEMA-C15, and NEMA-C19 — and lengths from 1 to 2 meters, ensuring compatibility with a wide range of gear and regions.

The Magic of Micro AIR Technology

What truly binds these cables together is in-akustik’s signature Micro AIR technology. By utilizing an internal cellular structure, these cables increase the volume of air around the conductors. If you think about it, air is an excellent insulator and having more of it reduces the cable's capacitance, which in turn lowers unwanted electrical interactions. This translates into a clearer, more faithful audio and power transmission — a detail that audiophiles will immediately recognize in their listening experience.

Manufactured with precision in Germany, both cables undergo individual assembly and rigorous testing to meet the highest standards. If you need a custom length, in-akustik is happy to provide bespoke solutions tailored to your unique setup.

The NF-404 Micro AIR is already available, with prices starting around €625 — a worthy investment for anyone craving that extra edge in sound purity.

Why Does Cable Design Matter?

If you’ve ever wondered why audiophiles fuss about cables, the answer lies in how these seemingly simple components influence the signal journey. The NF-404 and AC-404 highlight how thoughtful engineering — from conductor purity to shielding and geometry — all play a role in keeping your music untouched by noise and interference.
