About the L1 Dual Monaural Line-Stage
The CH Precision L1 line-stage amplifier is engineered for utmost transparency, ultra-low noise, and absolute stability. It features a fully discrete, balanced, and complementary design with ultra-short signal paths and meticulously selected components. The L1 uses separate left and right channel circuit boards to eliminate crosstalk and employs a software-driven R-2R network with precision metal-film resistors for precise volume control in 0.5dB steps. DC offset is continuously monitored and eliminated throughout the circuit, ensuring one of the quietest and most stable line-stages available. It delivers a dynamic, detailed, and accurate musical presentation without adding distortion or coloration, making it a benchmark in hi-fi preamplifiers.
