Furutech NCF Power Vault
Overview
The NCF Power Vault embodies the philosophy of electrical transmission developed by Furutech for over thirty years. This power strip goes beyond simple energy distribution by actively intervening in the audio chain. It reduces electromagnetic disturbances through absorption and induction techniques, without resorting to traditional filtering methods.
A chassis designed as an acoustic fortress
The NCF Power Vault’s enclosure reflects an industrial approach where every detail matters. CNC-machined from a solid block of aerospace-grade aluminum, the chassis features a unique compartmentalized structure. Each Schuko FI-E30 NCF (R) outlet occupies its own isolated compartment, creating eight independent zones that prevent the spread of electromagnetic interference between connected devices. This physical separation, combined with the precisely calculated thickness of the aluminum walls, forms an especially effective shield against external radio frequencies.
The brushed anodized finish is not just aesthetic: this surface treatment alters the crystalline structure of the aluminum, enhancing its thermal dissipation properties and resistance to micro-vibrations. The substantial weight of 10.8 kg gives the device mechanical inertia that contributes to overall stability, even in the face of vibrations transmitted from the floor or surrounding equipment.
An integrated grounding point directly on the chassis efficiently dissipates stray charges. This direct connection to the metallic mass of the enclosure creates a path of least resistance for electrical disturbances, diverting them away from sensitive audio circuits.
NCF technology: where nanocrystallography meets audio
At the heart of the NCF Power Vault lies the Nano Crystal² (NCF) formula, the result of decades of research at Furutech. This composite material combines specially developed crystals with ceramic nanoparticles and carbon powder. The crystals continuously generate negative ions that neutralize static electricity before it can accumulate. Simultaneously, they convert ambient thermal energy into far-infrared radiation, creating a passive energy dissipation effect.
The ceramic nanoparticles contribute their piezoelectric properties: under mechanical stress, they generate an electric field that counteracts parasitic vibrations. The carbon powder, meanwhile, ensures thermal conduction and contributes to overall mechanical damping. This synergy between active materials transforms mechanical, thermal, and electrical disturbances into dissipated heat, without creating resistance to current flow.
This NCF technology is present not only in the eight Schuko outlets but also in the integrated NCF Booster Brace supports. These multi-material hybrid structures mechanically stabilize each connection while locally applying the NCF effect. The anti-vibration grooves machined into their surface and the internal air chambers create zones of differential pressure that absorb mechanical resonances transmitted by the cables.
Star-wired electrical architecture and GC-303 absorption
The internal wiring uses a star topology, where the phase and neutral conductors converge at a central chamber. This configuration eliminates ground loops and equalizes impedance across all outlets, ensuring that each device receives exactly the same electrical potential. The conductors are made of twisted OCC α (Alpha) copper, a material produced by continuous casting using the Ohno process, creating exceptionally long copper crystals with less than 5 ppm oxygen impurities.
The central chamber contains the GC-303 absorbing material, a proprietary Furutech formula that captures electromagnetic interference generated by internal components. Unlike conventional filters that can introduce their own sonic signature, GC-303 passively absorbs EMI without creating additional AC resistance. This approach preserves the dynamics and fast response of even the most demanding power amplifiers.
The solder joints use a special alloy developed to minimize contact resistance and prevent the formation of micro-diodes at the junctions. Each connection point undergoes individual quality control to ensure optimal transmission across the entire electrical bandwidth.
The Alpha process: two-stage cryogenics and demagnetization
All metal components of the NCF Power Vault undergo Furutech’s exclusive Alpha treatment. The first stage immerses the parts in a cryogenic bath using liquid nitrogen or helium, reaching temperatures between -196°C and -250°C. At these extreme temperatures, the metal’s molecular structure reorganizes, atoms tighten, and internal stresses disappear. This permanent transformation measurably improves electrical conductivity.
The second stage applies the patented ring demagnetization process. Unlike conventional magnets that can create uneven zones of residual magnetization, this technique uses controlled attenuation of the magnetic field to completely eliminate any trace of magnetism. Treated metals return to an electrically neutral state, eliminating eddy currents that can generate noise in the audio signal.
Acoustic performance and practical use
In use, the NCF Power Vault profoundly changes the behavior of the audio system. The soundstage gains depth and stability, with instruments occupying more precise positions in three-dimensional space. Micro-details emerge from a now-silent background, revealing ambient nuances and reverberation previously masked. Dynamics are expressed without compression, from the most delicate pianissimos to the most powerful fortissimos.
Low frequencies particularly benefit from the stable power supply: they become tighter, faster, with better definition of individual notes. The midrange gains in naturalness and presence, with voices acquiring a more organic texture. High frequencies extend without harshness, with a natural decay of harmonics.
For home theater systems, the improvement is evident in more intelligible dialogue, more precise spatialization of effects, and better channel separation. The video image can also benefit from a cleaner power supply, with less digital noise and sharper edge definition.

Frequently Asked Questions
Does the NCF Power Vault require a break-in period?
The NCF materials and OCC α conductors benefit from a stabilization period of about 100 to 200 hours of use. During this phase, the electrical and mechanical properties gradually stabilize. The most noticeable improvements generally appear after the first 50 hours, with continued refinement of performance until full stabilization.
What is the difference between star wiring and traditional series wiring?
Star wiring connects each outlet directly to the main power entry point via dedicated conductors, eliminating interactions between devices. In series wiring, current passes successively through each outlet, creating mutual modulations and variable voltage drops. Star topology ensures identical impedance and optimal electrical isolation between each output.
Can the GC-303 material become saturated or lose effectiveness over time?
GC-303 operates through passive absorption and thermal conversion, with no active components that could age. Its molecular structure remains stable indefinitely under normal usage conditions. Unlike electronic filters that can degrade, GC-303 maintains its EMI absorption properties without maintenance or replacement.
How should I ideally position the NCF Power Vault in my setup?
Place the unit on a stable surface, away from power transformers and sources of mechanical vibration. Using optional isolation feet can further improve performance by mechanically decoupling the chassis. Avoid placing objects on top to allow for optimal thermal dissipation. The length of the main power cable should be minimized while avoiding mechanical stress.
Are all eight outlets identical, or are some optimized for specific uses?
All FI-E30 NCF (R) outlets are technically identical and receive the same level of treatment. However, the order of connection can subtly influence electromagnetic interactions between devices. It is generally recommended to connect digital sources at the ends and amplifiers in the center to minimize mutual interference.
Does the NCF Power Vault replace a power conditioner?
The NCF Power Vault takes a different approach from traditional conditioners. Rather than actively filtering, it passively absorbs disturbances without limiting bandwidth or dynamics. For setups suffering from severe mains pollution, pairing with a regenerator or isolation transformer can be beneficial, with the NCF Power Vault then handling the elimination of residual high-frequency disturbances.
