The Keces Audio P9 is a dual-output audiophile linear power supply , inspired by the P28 reference model. Designed to deliver absolute purity of current, it ensures perfectly stable voltage, without ripple or parasitic noise. Thanks to its oversized toroidal transformer and its discrete component architecture, it delivers a power supply of exemplary precision, optimizing the dynamics and transparency of any Hi-Fi system, DAC, streamer or preamplifier.
 
Highlights — Keces Audio P9
Dual independent output with separate control circuits for each zone.
Zone I : 5 V / 7 V / 9 V / 12 V – up to 4 A continuous.
Zone II : 12 V / 15 V / 19 V / 24 V – up to 6 A (peak 7 A).
100% discrete design without integrated circuits, inherited from the P28, P14 and P6.
Shielded toroidal transformer with low magnetic radiation.
Ultra-low noise : almost zero ripple and no vibration at 50 Hz.
Over-temperature (OTP) and overload protection.
Solid aluminum chassis with anti-interference and optimized heat dissipation.
