What customers say
The Oyaide L/i50EXs Power Cable is viewed as a vital upgrade for serious listeners, delivering transformative sonic improvements. Users consistently note a significantly lowered noise floor, which directly enhances system clarity and reveals previously hidden micro-details. The sound presentation becomes tighter, more articulate in the bass, and smoother across the upper frequencies, resulting in a more focused, three-dimensional soundstage. Beyond performance, the physical build quality inspires confidence due to the high-grade conductors and precision connectors. While the cost is substantial, owners agree this cable unlocks true high-end potential, justifying the investment for those seeking ultimate audio refinement.
Know before you buy
The star-quad configuration is designed to minimize inductance and cancel out electromagnetic interference. By reducing this background noise, the cable allows your audio equipment to deliver a cleaner, more detailed signal.
The combination of silver and rhodium plating provides excellent conductivity and corrosion resistance. This ensures a stable, low-resistance connection that helps maintain signal integrity and clarity across the frequency spectrum.
While the silicon rubber provides superior resonance absorption and mechanical strength, it is flexible enough for most standard setups. However, at 10.6mm in diameter, it is a substantial cable, so ensure you have enough clearance behind your components.
Yes, the L/i50EXs features a standard IEC C13 connector, which is the most common power input found on amplifiers, DACs, and other high-fidelity audio equipment. It is rated for 125V and 15A, making it suitable for most domestic audio systems.
The reinforced sleeve is specifically engineered to prevent the buildup of static electricity on the cable's surface. By mitigating static discharge, the cable helps maintain a lower noise floor, which is essential for preserving the resolution of your music.
