As systems become more resolving, the quality of power delivery becomes increasingly important—not just in terms of stability, but in how it affects noise and signal integrity across the entire component. The X1 is CH Precision’s external power supply, designed to enhance the performance of compatible components by offloading and refining their power delivery. It extends the brand’s modular philosophy, allowing systems to be upgraded without replacing core components. In listening, the effect is subtle but cumulative. Background noise is reduced, allowing low-level detail to emerge more clearly. Imaging gains definition, and dynamic contrasts feel more immediate without becoming exaggerated. It integrates seamlessly into existing CH systems, connecting to components such as the L1 or C1.2 to provide dedicated, isolated power. Technically, the X1 features multiple independently regulated power outputs, reducing interaction between internal circuits. By separating power supply functions from the main chassis, it minimizes electromagnetic interference and improves overall system stability. For systems already operating at a high level, the X1 offers a refinement upgrade—one that improves clarity and control without altering tonal balance.
