P9 9A Ultra Low Noise Linear Power Supply
Flagship-Level Power Architecture for Pure Sonic Energy
High-Quality Toroidal Transformer (In-House Production)
    Developed and manufactured in-house by KECES, our toroidal transformer delivers clean and stable power through precision winding and
    carefully selected materials. It effectively reduces background noise, enhances detail resolution, and lays a solid foundation for superior
    sonic performance.
Separate Ground for Each Output Rail
    Minimizes cross-interference between circuits, improving channel separation and sound layering.
Fully Discrete Component Architecture Inspired by the P28
    Built entirely with discrete components, this design prioritizes sound quality, delivering a more natural and refined tonal character.
Ultra-Low Ripple Noise Design
    Ensures the audio signal remains free from power-related interference, resulting in a cleaner and more transparent soundstage.
Dual Output Design: 4A and 5A (Peak up to 7A)
    Supports multiple devices with powerful and dynamic energy delivery.
Gold-Plated DC Jack
    Reduces contact resistance and improves conductivity, resulting in more transparent sound and richer micro-details.
AC Inlet Module with OCC Silver Wiring & 2oz Copper PCB
    Enhances current flow and transient response, delivering greater dynamic range and musical fullness.
Ground Terminal Added
    Offers advanced grounding options to reduce system noise and enhance soundstage stability and depth.
No Humming or Buzz at 50Hz and Peak Load
    Maintains absolute silence even under heavy load, showcasing exceptional stability and reliability.
Over Temperature Protection (OTP)
    Provides safety and ensures long-term stable operation.
