Know before you buy
This cable blends two high-purity copper types to optimize signal flow. By combining Furutech’s Alpha OCC with DUCC Ultra Crystallized Copper, the design reduces crystal grain boundaries, resulting in a more efficient, less direction-sensitive path for your power signal.
Despite its robust 11-gauge construction and multi-layer shielding, the DPS-4.1 uses flexible PVC sheathing. While it is a substantial cable with a 17mm overall diameter, it is designed to be manageable during installation in high-end audio setups.
The cable utilizes a comprehensive multi-layer approach, including copper foil, braided OFC, and a paper barrier. This combination is specifically engineered to minimize electromagnetic interference, ensuring that external noise does not compromise the purity of the power delivery.
Yes, the 11 AWG (4.02 sq. mm) conductor size is well-suited for high-current applications. It provides the necessary capacity to support power-hungry components like monoblock amplifiers or integrated power stages without restricting current flow.
While many OCC cables are highly sensitive to direction, the advanced conductor alignment in the DPS-4.1 makes it significantly less sensitive. This simplifies the installation process while maintaining the high-fidelity performance expected from a premium power cable.
These audio-grade materials are chosen for their superior dielectric properties. By using FEP for inner insulation and P.E. for the outer layers, the cable maintains excellent signal integrity and prevents degradation of the electrical current as it travels to your equipment.
