The I1 is an integrated amplifier with built-in DAC and phono stage from CH Precision, a Swiss manufacturer renowned for uncompromising digital source engineering, sharing chassis dimensions with the brand's D10 transport. The I1 brings CH Precision's meticulous engineering to a comprehensive integrated solution.
Key specs that matter
One balanced XLR input and two single-ended RCA inputs are provided, alongside a built-in D/A converter and phono stage. Input impedance is switchable between 94k or 600 ohms balanced, or 47k or 300 ohms single-ended - a flexible arrangement suited to both line-level and phono cartridge inputs sharing the same connector. Output power is 2 x 100W into 8 ohms, rising to 2 x 175W into 4 ohms. At 440 x 440 x 133mm and 33kg, the I1 shares matching chassis dimensions with CH Precision's own D10 transport.
Sound and use context
Expect exceptionally clean, uncompromising performance reflecting CH Precision's broader engineering philosophy, combined with comprehensive built-in DAC and phono functionality within one integrated chassis.
Pairing
The built-in DAC and phono stage cover digital and vinyl sources directly without additional outboard components, and CH Precision's own D10 transport shares matching chassis dimensions for a visually coherent system.
Alternatives
CH Precision's broader electronics catalogue, including the T10 master clock, offers natural companion components for buyers building a coherently voiced, entirely CH Precision-based system.
