CH Precision C10 Mono with clock card

CH Precision C10 DAC with additional power supply and clock card.

The C10 DAC marks the beginning of your journey to CH Precision’s ultimate digital front-end. Built on our modular design ethos, this two-piece DAC redefines what’s possible for digital front ends—even in its simplest form. The C10 is a complete, stand-alone DAC for those seeking ultimate performance in a compact, self-contained configuration. For those who wish to go further, its modular, expandable architecture allows it to be precisely configured and upgraded to match each customer’s system and aspirations.

C10 Digital to Analog Converter

Cutting-edge from Inception

The C10 builds on the proven PCM1704 converter chip, now implemented in a sophisticated dual-differential DSQ™ Phase Array. Sixteen converters—four per polarity for each channel—are directed by our proprietary PEtER algorithm, a 32-bit fixed-point DSP engine that prepares the signal for the final 24-bit conversion. Data is fed sequentially across the array, a structure that demands impeccable clocking and algorithmic control. Following the conversion process, our Bessel filter preserves the analog signal’s temporal integrity, maintaining constant group delay to a tolerance of under two femtoseconds. With oversampling extended to 64x, the C10 achieves a new threshold of time-domain accuracy and musical refinement.

Your Journey Begins at the Peak

The C10 was conceived at the forefront of audio innovation—every element engineered to establish a new benchmark in digital playback. To achieve this performance, we redesigned the power architecture and physical construction. Housed in a separate enclosure, the C10’s power supply utilizes eleven ultra-stable DC feeds, which supply four galvanically isolated zones inside the audio unit: digital, clock, and dual DACs. A symmetrical layout places input cards at the center and DACs on either side, each with matched clock paths.

With the C10, CH Precision created a digital source that transcends measurement and specification—one that breathes life into music with effortless realism, depth, and emotional connection. The C10 reveals not just the detail in a recording but the intent behind it, drawing the listener closer to the original performance. It is the culmination of decades of refinement in digital design and the embodiment of CH Precision’s unwavering pursuit of musical truth.

Tailored for Your System. Designed for Your Future.

The C10’s modular architecture gives you the power to configure your digital front-end exactly the way you want it. Three identical input slots allow seamless customization to suit your system’s needs. Every C10 comes equipped with CH Precision’s proprietary Digital IN HD card as standard, leaving two additional slots available for easy expansion.

The C10 offers the Ethernet Streaming HD board option for superior performance with local servers (UPnP, Roon, etc.) or online services such as Qobuz, TIDAL, and Internet radio. This board also includes a USB input for direct connection to digital sources. Unlike most high-end DACs that rely on third-party streaming modules, CH Precision’s design ensures uncompromising streaming fidelity, guaranteeing that every performance arrives with exceptional clarity, coherence, and emotional impact.

The C10’s optional Clock Board provides one clock input and two clock outputs via high-quality BNC connectors, allowing seamless integration with an external master clock, such as the CH Precision T10 Time Reference.
