About the P1

The CH Precision P1 is a reference-grade phono preamplifier engineered entirely in-house in Switzerland, featuring fully discrete, dual-mono architecture designed to preserve the fragile phono signal with remarkable precision and tonal purity. Built to the highest standards with aluminum alloy construction and no visible screws, the P1 combines proprietary gain stages, ultra-precise loading control, and intelligent software-driven setup tools to accommodate every cartridge type from vintage mono to the latest low-output moving coil designs. The unit features a modular, upgradeable design that allows owners to expand performance over time, with the optional X1 External Power Supply available to further lower the noise floor and enhance microdynamic resolution. The P1's architecture isolates left and right channels within a single chassis, ensuring exceptional channel separation and low noise from the start, while its setup wizard guides users to optimal settings with confidence and precision.
