The Keces P9 is a high-quality linear power supply from the Pier series, developed for demanding audiophiles. It offers two independently adjustable outputs with up to 5 A each (7 A peak) and covers voltages from 5 V to 24 V. Zone I provides 5 / 7 / 9 / 12 V, Zone II 12 / 15 / 19 / 24 V – ideal for the simultaneous operation of streaming devices, DACs, Roon Core, routers, or turntables.

The technology is based on a fully discrete regulation architecture, as used in the top-of-the-line P28 and P14 models. Integrated ICs are intentionally avoided to ensure extremely low ripple, stable voltage curves, and maximum sonic purity. A potted toroidal transformer ensures a vibration-free and low-interference power supply.

The housing is made of solid aluminum, the DC jacks are gold-plated, and protective mechanisms such as over-temperature and over-voltage protection are integrated. With a weight of around 5.5 kg and compact dimensions (approx. 22 × 26 × 8 cm), the P9 is a solid foundation for any high-end setup.

The Keces P9 delivers clean, stable power for sensitive HiFi components and improves dynamics, detail, and the quietness of the soundstage
