What customers say
The VIABLUE X-40 Silver AC Power Cable earns high praise for its exceptional build quality and significant sonic improvements. Customers consistently note the robust construction, featuring a substantial cross-section and superior shielding, making it feel incredibly durable and visually impressive. The primary performance benefits cited are enhanced dynamics and a lowered noise floor, resulting in greater clarity and a more expansive soundstage. High current components show tighter bass and faster transient response. While the investment is premium, enthusiasts feel the performance gains justify the cost for reference systems. The main drawback mentioned is the cable's stiffness, which can complicate installation in tight areas. Overall, it is regarded as a benchmark component for maximizing power delivery efficiency.
Know before you buy
Silver-plated Oxygen-Free Copper (OFC) conductors provide superior electrical conductivity compared to standard copper. This ensures a cleaner, more efficient power delivery to your components, which helps maintain signal integrity and reduces potential distortion in high-fidelity audio systems.
The cable utilizes a dual-layer approach with both braided and aluminum foil shielding. This design effectively blocks electromagnetic and radio frequency interference (EMI/RFI) from external sources, ensuring that your power supply remains clean and free from noise that could otherwise degrade sound quality.
Despite its robust 14mm diameter and high-quality shielding, the X-40 is designed with an ultra-soft sheath to maintain high flexibility. This makes it significantly easier to route through tight spaces or around corners compared to many other shielded power cables.
Yes, the X-40 is fully compatible with VIABLUE™ ferrite filters. You can easily add a filter to the cable to further suppress high-frequency noise if your specific environment requires additional interference mitigation.
This version is terminated with a standard NEMA 5-15P US wall plug and an IEC C15 connector for your device. Both ends feature VIABLUE™ T6s connectors with 24-carat gold-plated contacts to ensure a secure, corrosion-resistant connection.
The connectors feature a double-screw strain relief system. This design firmly anchors the cable to the plug housing, preventing accidental disconnection and ensuring the internal conductors remain stable even if the cable is pulled or moved.
