Last weekend afternoon, a low-key yet highly anticipated music appreciation event quietly unfolded at the New Han Family Entertainment Center. The star of the event wasn’t a million-dollar amplifier or massive speakers, but rather a seemingly unassuming “German inakustik NF-4005 AIR signal cable.” Paired with Dynaudio Confidence 60 three-way floorstanding speakers, a Burmester 089 CD player, a 088 preamplifier, and a 218 stereo power amplifier, it delivered a high-purity music experience.

The demonstration system used the Burmester 089 CD player as the source, with the 088 preamplifier’s precise volume control and the 218 power amplifier’s 270W/4Ω power driving the Dynaudio Confidence 60 speakers featuring Esotar³ tweeters and MSP mid-bass units. However, the heart of the entire system lies in the cables of the inakustik 05 series, especially the NF-4005 AIR balanced signal cable connecting the preamplifier to the power amplifier.

How inakustik AIR Technology Revolutionizes Signal Transmission

The design philosophy of the NF-4005 AIR signal cable directly addresses the physical limitations of dielectrics. Its patented Air Helix 5th generation technology is implemented with a clever keel support structure. To reduce skin effect and capacitive reactance, three independent wires, each made of multi-core braided oxygen-free copper conductors, are suspended in the air, with the conductor spacing precisely controlled within a 0.35mm error range, reducing dielectric loss to below 0.0001. This architecture is like building a conductor viaduct within the entire cable, allowing signals to be transmitted with almost zero capacitive and inductive reactance.

During the live demonstration, the NF-4005 AIR’s point-to-point air spiral technology translated into astonishing detail resolution. When playing male vocals, listeners could clearly perceive the subtle nasal resonance during the singer’s breaths, as if lifting an invisible veil.

High-Frequency Penetration: When playing female vocals, the NF-4005 AIR exhibited a clear and transparent texture. The high frequencies were light and airy, fully unleashing the limits of the Confidence 60’s Esotar³ high frequencies. Every note was incredibly precise, creating an ethereal sense of space.

Mid-Frequency Density and Layering: In reproducing string instruments, the NF-4005 AIR imparted a unique transparency to the violin. The string sound permeated the multi-track mix, its precise positioning appearing slightly to the left of the soundstage. The viola and other ensemble instruments were layered and distinct, like a three-dimensional nebula.

Low-Frequency Control
When faced with the “Zambra” section of the Spanish dance “Flamenco,” the NF-4005 AIR, through the Burmester 218 power amplifier, demonstrated astonishing transient response, capturing the impact of the dancers’ footsteps on the floor. The Confidence 60’s 24cm woofer exhibited excellent control, revealing the texture of the low frequencies and the lingering resonance of the floor vibrations.

In addition to the NF-4005 AIR signal cables, the event also utilized Burmester’s LS-2405 AIR speaker cables and Referenz AC-2405 power cables. The AIR series cables’ low capacitance characteristics perfectly complement Burmester’s exclusive X-AMP amplification module, preventing high-frequency phase shift, which is especially crucial when playing large-scale Mahler symphonies. “When the string section emerged in the fourth movement of Mahler’s Fifth Symphony, the stable and unwavering positioning of the 100-member orchestra demonstrated the cables’ ability to suppress system timing errors.”

Redefining the Benchmark of Signal Transmission: This experience overturned the misconception that “cables are merely accessories.” The NF-4005 AIR, with its scientifically designed structure, reduces signal distortion to a level imperceptible to the human ear, while maintaining just the right amount of warmth in its musicality. When the total system price exceeds one million NT dollars, a 30,000 NT dollar signal cable becomes a crucial piece of the puzzle. Perhaps this is the essence of high-end audio—pursuing that 1% of pure emotion amidst countless details.
