CH Precision's New 10 Series Digital System

by The Audio Beat | May 5, 2025

H Precision calls its new 10 Series digital system, "a uniquely scalable and performance-driven solution." It comprises four main products, each designed to function independently or as part of the integrated 10 Series digital system.

The C10 Master DAC ($95,000 with C10 power supply) features CH Precision’s DSQ Phase Array architecture and proprietary PEtER DSP engine. Its uses sixteen converters -- four per polarity -- with 64x oversampling and sequential data flow. Signals are reclocked and upsampled to 705.6/768kHz. All PCM signals, from CD to  DXD, are treated identically, varying only in interpolation factor. DSD is converted in a single step to 24-bit/705.6kHz PCM.

The C10 Conductor ($75,000 with C10 power supply) is a dedicated digital control hub that isolates digital signal processing from analog conversion. It manages source selection, analyzing input signal phase and frequency, and executing synchronous upsampling via multiple DSP modules. It also transmits audio data and clocking commands to the D10 over the proprietary CH-Link -- a low-noise connection designed for signal integrity.

The D10 Reference Transport ($95,000 with D10 power supply) showcases the proprietary Mechanically Optimized Reading & Stability Enhancement (MORSE) transport mechanism -- an in-house innovation engineered to achieve reference-level precision. It uses a brass core encased in an aluminum exoskeleton -- a balance of mass and internal damping that provides density and thermal stability, stiffness and resonance control. The entire laser assembly is mounted within this composite structure and suspended via alpha-gel isolators, decoupling the mechanism from external vibrations and mechanical chassis noise. The D10 includes a precision circular level mounted directly on the transport mechanism, allowing for calibration of the disc’s rotational plane.

T10 Master Clock ($26,500) is an ultra-stable timing reference offering sub-femtosecond precision to the entire 10 Series digital system. Its 10MHz oven-controlled oscillator (OCXO) achieves low phase noise. It is thermally stabilized within a solid aluminum block to ensure consistent performance. Referencing all digital components to the T10 reduces timing errors, "unlocking deeper resolution," according to CH Precision, along with enhancing "spatial precision, and musical flow."

Finally, in keeping with the CH Precision's goal of providing system scalability, a separate C10 power supply ($36,000) can be added to the C10 DAC for true dual-mono performance.
