The P1 is a flagship phono preamplifier from CH Precision, built with comprehensive six-input connectivity and an extraordinarily wide bandwidth. The P1 brings CH Precision's most accomplished current engineering to serious, versatile phono amplification.
Key specs that matter
Three balanced XLR inputs and three single-ended RCA inputs are provided - a comprehensive six-input connectivity set. MC current-sensing input impedance is an exceptionally low 0.1 ohms, with MM/MC voltage input impedance variable between 100,000 and 20 ohms - a remarkable range of adjustability. Gain is a substantial 70dB. Playback EQ curve accuracy is a remarkable 0.1dB. Frequency response spans an extraordinary 0Hz to 400,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is 0.01%. At 440 x 440 x 133mm and 20kg, the P1 represents CH Precision's flagship-tier current phono engineering commitment.
Sound and use context
Expect exceptionally clean, accurate RIAA equalisation reflecting the remarkable 0.1dB EQ curve accuracy, combined with the remarkable impedance adjustability accommodating virtually any moving-coil or moving-magnet cartridge.
Pairing
The comprehensive six-input connectivity comfortably accommodates multiple turntables or tonearms, and CH Precision's own C1.2 Mono or C10 DACs share the brand's coherent modular engineering philosophy.
Alternatives
CH Precision's own M10 Stereo power amplifier shares the brand's coherent engineering philosophy, forming a natural companion component.
