Furutech DPS-4.1 Reference α-OCC/α-DUCC (11 AWG) Power Cable - Per Metre

Furutech DPS-4.1 Delivers Ultimate High-End Power Transmission

Furutech DPS-4.1 power cable is a reference-grade, ultra-high-performance audio-grade power cable engineered for audiophiles who demand uncompromising current delivery and sonic purity. Designed with an obsessive focus on conductor quality, dielectric materials, and electromagnetic shielding, the DPS-4.1 combines scientific innovation with precision Japanese craftsmanship to become the ultimate power transfer solution for elite hi-fi and high-end audio systems.

Furutech DPS-4.1 Uses α (Alpha) OCC-DUCC Conductors for Superior Signal Purity

Furutech DPS-4.1 power cable features α (Alpha) OCC-DUCC conductors, a hybrid copper architecture that achieves exceptionally low resistance and ultra-clean signal transmission. The inner structure utilises a sophisticated arrangement of Furutech’s Pure Transmission α-OCC and Mitsubishi-regulated DUCC (Ultra Crystallised High Purity Copper), optimised for directional consistency and grain-boundary minimisation.

The DPS-4.1’s inner conductor comprises 79 strands of 0.18mm α-OCC copper twisted in a right-hand rotation, supported by an inner layer of 37 strands of α-DUCC wound leftward, and finished with an outer layer of 42 strands of α-DUCC twisted rightward. This three-layer composite architecture forms a highly efficient 11AWG (4.02mm²) conductor path capable of supplying current with high instantaneous delivery and exceptional transient fidelity—ideal for power amplifiers, high-draw DACs, and premium source components.

Furutech DPS-4.1 Combines OCC-DUCC with Cryogenic and Demagnetisation Processing

Furutech’s proprietary Alpha Processing elevates the DPS-4.1’s performance by applying deep cryogenic treatment followed by a controlled demagnetisation cycle. This dual-stage process improves conductor lattice structure, lowers the magnetic field noise floor, and stabilises the signal pathway—translating to audible improvements in dynamic resolution, spatial depth, and harmonic integrity.

Unlike typical OFC or standard OCC cables, the DPS-4.1 takes full advantage of DUCC’s ultra-aligned grain orientation. Mitsubishi Materials’ exclusive process reduces crystal junctions and aligns copper grains for more linear current flow. The result is a conductor that exhibits less directionality than traditional OCC while maintaining coherence and tonal accuracy across the frequency spectrum.

Furutech DPS-4.1 Features Multi-Layer Dampening and Full Electromagnetic Shielding

Furutech DPS-4.1 audio power cable incorporates a complex internal layering of premium insulation and dampening materials to suppress vibrational energy and shield electromagnetic interference. Each conductor is individually insulated with high-grade FEP (fluoropolymer) to ensure chemical stability and low dielectric loss. The colour-coded outer insulation uses audio-grade polyethylene, ensuring long-term durability and electrical integrity.

A black inner sheath made of audio-grade flexible PVC integrates Nano-Ceramic and Carbon particle composite materials. This compound acts as a passive vibration absorption matrix, damping high-frequency mechanical resonances and reducing microphonic distortions. The layered shielding includes a tightly wound copper foil, braided OFC mesh, and a paper wrap—all meticulously arranged to eliminate radiated EMI and RFI from external sources.

With a total outer diameter of approximately 17mm and an elegant deep purple PVC outer sheath, the DPS-4.1 offers robust physical protection while maintaining flexibility for installation in premium listening environments.

Furutech DPS-4.1 Suits High-Current Demands in Ultra-Fidelity Systems

Furutech DPS-4.1 high-end audio power cable is engineered for ultra-fidelity applications where maximum current stability and minimal signal degradation are essential. Its 7N-class copper purity, 11AWG gauge, and balanced conductor geometry make it the ideal choice for end users upgrading the power infrastructure of mono block amplifiers, preamp stacks, high-end DACs, and reference power conditioners.

This cable is not simply a passive component; it's a transformative signal conductor that enhances tonal balance, transient clarity, and background silence in high-resolution playback chains. Whether installed in a reference-level listening room or a professional mastering suite, the DPS-4.1 forms the backbone of a clean, high-current audio ecosystem.

By integrating state-of-the-art metallurgy with bespoke mechanical damping, the Furutech DPS-4.1 sets a new benchmark in high-performance, high-purity power cable design.
