Product Description

Any great line-stage must possess transparency, ultra-low noise performance, and absolute stability. It must anchor the incoming signals and deliver them onwards, propelled from a firm footing that ensures dynamic and musical authority. It must pass the source signals in your system, without limitation or disturbance, leaving no trace of itself on their passage. Any great line-stage needs to be the next best thing to sonically and musically invisible, the hi-fi equivalent of effortlessly enacting its audio superpower.

Like all CH Precision products, the L1 uses fully discrete, balanced, and complementary design, ultra-short signal paths, and exactly selected components. It is fed from heavily regulated and filtered power supplies, is wide-bandwidth, high slew-rate, and DC-coupled. But in this critical application, that’s not enough. It’s one thing to eliminate unnecessary components from the signal path and eliminate DC offset at the inputs, but the L1 takes things much, much further than that. Completely separate left and right channel circuit boards prevent crosstalk, while a sophisticated, software-driven R-2R network for each channel employs precision metal-film resistors, allowing precise level control in 0.5 dB steps with the minimum possible number of components. DC offset is monitored and eliminated not just at the inputs but throughout the volume control ladder and at multiple points throughout the entire circuit. That makes the L1 not just one of the quietest line-stages ever built, but also one of the most quiet in operation.

The L1 goes calmly about its business, the anchor to which the system’s absolute spatial and temporal stability are tied, the root of its remarkably low noise floor and sudden dynamic response. In many ways it’s the understated star turn that sums up the whole system.”
