[H5] Precision as Principle
At CH Precision, engineering is not a department, it is our identity. Born from the convergence of disciplines that span high-performance audio, software development, and advanced digital systems, our team brings a breadth of experience that is unparalleled in this industry. But more telling than our collective résumé is how we choose to apply it.
​
We pursue engineering as a means of serving music, not conventions. When established solutions fall short, we develop our own. For that reason, all engineering disciplines—circuit design, software architecture, and mechanical development—are executed entirely in-house. This is not about control for its own sake; it is about the freedom to question assumptions, refine ideas, and build systems whose behavior is governed by musical priorities rather than technical convenience. With more than half of our team dedicated to core technical roles, each product is conceived as a coherent whole from the outset, designed to meet clearly defined standards of performance, stability, and long-term reliability.
​
We embrace a distributed manufacturing model, partnering with expert fabricators and specialists across Switzerland. In itself, this is not unusual. What sets CH Precision apart is the level of complexity, precision, and performance we demand from this model, and the fact that final assembly, testing, and quality control remain entirely under our roof. The result is not only exceptional consistency but also an unbroken line of accountability from concept to completion.
​
Ultimately, this discipline exists in service of music. True value is not determined by cost, but by how faithfully a product conveys musical intent, and how reliably it does so over time. When engineering, craftsmanship, and accountability are aligned, the result is not merely technical excellence, but a deeper and more enduring connection to the performance itself.Learn More

[IMG: CH D10 Front White-2-Edit.jpg]
[H2] D10 Reference Transport
[H5] A Transport Without Compromise
[IMG: CH Precision D10 Reference Vault Open]
The D10 Reference Transport sets a new standard in optical disc playback, establishing itself as the most advanced transport ever created. Its design draws directly from the D1.5’s critical insights and proven architecture. Building on the foundation of its sibling, the D10 Reference Transport redefines every aspect of disc data retrieval, elevating precision and fidelity to a new level.
​
At the heart of the D10 Reference Transport is CH Precision’s innovative MORSE (Mechanically Optimized Reading & Stability Enhancement) laser mechanism. Entirely designed and engineered by CH Precision, MORSE establishes new benchmarks in mechanical precision, stability, and data extraction accuracy. Advancing beyond the single-material design of the D1.5, the D10 Reference Transport’s suspended transport platform employs a sophisticated composite construction consisting of an aluminum skin encasing a dense brass core, significantly enhancing vibration damping and overall mechanical robustness. Supported by alpha-gel isolators and weighing an impressive 13 kilograms, more than ten times heavier than its predecessor’s mechanism, the MORSE assembly suppresses vibrations below 20 Hz, reducing mechanical noise and preserving the integrity of the digital signal.
[IMG: CH D10 Down Shot Gradient]
[H5] Silence. Stability. Sonic Truth.
Among the many innovations that distinguish the D10 Reference Transport, one of the most quietly transformative is the inclusion of a precision circular level mounted directly on the transport mechanism itself. Unlike conventional designs, which rely on the external chassis for leveling, this internal calibration tool allows the optical pickup to be aligned with exceptional accuracy, completely independent of chassis position. This seemingly simple addition has profound implications. By optimizing the rotational plane of the disc with exacting precision, the D10’s transport mechanism ensures uniform tracking, minimizes mechanical stress, and reduces reliance on error correction. The result is superior rotational stability, improved data retrieval, and a measurable reduction in timing smear and jitter.
​
This meticulous approach continues with the D10’s motorized top-loading architecture. The vertical access Disc Vault is not only mechanically elegant but functionally essential, eliminating the disc wobble and axial instability often associated with traditional drawer mechanisms. A hybrid-action sealing door completes the motion with controlled precision, reflecting the same commitment to mechanical integrity found throughout the design. Every detail, from mass damping to movement control, has been selected in direct service of sonic performance.
​
Taken together, these mechanical innovations enable the D10 to reveal subtleties of tone, spatial layering, and rhythmic coherence that conventional transports often overlook. By addressing the physical interface with the disc at a level few manufacturers consider, CH Precision has extended the practical limits of optical playback, unlocking a level of musical expression that approaches the master recording.
[IMG: MORSE Mechanism]
[H5] Mechanical Silence, Digital Precision
Most manufacturers, out of necessity, rely on OEM transports originally designed for mid-fi products, even in components that sell for five and six figure prices. CH Precision categorically rejects this compromise. Rather than adapting an off-the-shelf mechanism, CH set out to design and build the most ambitious CD transport in the history of audio, fully engineered and manufactured in-house.
​
At the heart of the D10 Reference Transport lies CH Precision’s MORSE mechanism, Mechanically Optimized Reading & Stability Enhancement, a laser transport system conceived, designed, and engineered entirely within its facility. MORSE represents the culmination of CH’s pursuit of mechanical silence and digital precision, establishing new benchmarks for stability and data integrity. Building on the principles established in the D1.5 Transport, the D10’s suspended platform employs a sophisticated composite structure consisting of a dense brass core encased within a precision machined aluminum shell. This multi-material construction combines mass, stiffness, and damping in ideal proportion, dramatically reducing self resonance and improving mechanical grounding.
​
Supported by four tuned Alpha Gel isolators, the 13 kilogram assembly, more than ten times heavier than the mechanism in the D1.5, achieves a suspension resonance below 20 Hz, well beneath the frequencies at which the disc operates. This isolates the laser assembly from both internal and external vibrations, allowing it to operate with exceptional precision and temporal stability, free from mechanical interference that could compromise data retrieval.
​
MORSE exemplifies CH Precision’s design philosophy: engineering in service of musical truth. By addressing the mechanical domain with the same rigor applied to digital processing, the D10 achieves data extraction of remarkable purity, transforming physical stability into audible serenity.
[IMG: CH D10 Front Straight]
[H5] Power, Purity, and Precision:
The D10 External PSU
Like all 10-Series reference components, the D10 Reference Transport utilizes a dedicated external power supply (PSU). Engineered with exceptional current and voltage reserves comparable to many power amplifiers, the PSU delivers stable, ultra-clean power to the transport mechanism, minimizing noise and preserving digital signal integrity.
​
Four galvanically isolated domains independently supply the transport motor, control, DSP, and master clock, eliminating crosstalk and ensuring pristine electrical conditions. Cascaded regulation throughout guarantees consistently clean, stable current to every subsystem. With a total mass of 66 kg (145 lbs) including the power supply, the D10 firmly establishes itself as the ultimate heavyweight in digital reproduction.
​
CH Precision’s unwavering dedication to engineering integrity guarantees precise, flawless data retrieval from SACD, CD, and MQA CD optical discs. Laser tracking accuracy is maximized, read errors are minimized, and time-domain integrity is preserved. The sonic result is profound musicality: enhanced transparency, expanded soundstage depth, greater low-level detail, and authentic timing and flow, revealing the emotional depth and nuance of every recording.
[IMG: CH D10 UP White Background]
[H5] The D10 Reference Transport:
Ultimate Precision Meets the Disc
For listeners seeking the finest in disc playback, the D10 Reference Transport is the natural companion to the C10 Reference DAC while remaining fully compatible with third-party DACs. Designed to extract maximum performance from SACD, CD, and MQA-CD media, the D10 delivers exceptional temporal accuracy, tonal integrity, and musical refinement. A low-noise transport mechanism, galvanically isolated digital outputs, and a precision engineered mechanical platform ensure that the signal presented to the downstream DAC, whether CH or otherwise, is exceptionally pure, stable, and free from jitter, timing smear, or electrical contamination.
​
Yet the D10 is not limited to CH systems. As a standalone component, it offers a state of the art upgrade for any high performance digital front end. Whether paired with CH’s proprietary digital architecture or a third-party reference converter, the D10 restores optical playback to its rightful place among the most revealing and emotionally compelling listening formats.

[H2] C10 Reference DAC
[H5] Faithful to the Event in Space and Time
The C10 Reference DAC is the point of entry into CH Precision’s ultimate digital front end. Built on our modular, component-additive design ethos, this two-piece DAC establishes a new reference for digital performance even in its most compact form. It is a complete, stand-alone converter for listeners seeking exceptional performance in a self-contained configuration, while its expandable architecture allows it to be configured and upgraded with precision as a system evolves.
​
The C10 advances CH Precision’s proven R-2R conversion architecture to a new level of refinement. Its dual-differential DSQ™ Phase Array employs sixteen precision resistor networks, driven by our proprietary PEtER algorithm, a 32-bit fixed-point DSP engine that prepares the signal for final 24-bit conversion. Data is fed sequentially across the array, a topology that demands exact timing control. Following conversion, a CH-engineered Bessel filter preserves temporal integrity by maintaining constant group delay with tolerance measured in femtoseconds. With oversampling extended to 64×, the C10 sets a new benchmark for time-domain precision and musical naturalness.
[IMG: CH Precision C10 Top]
[IMG: CH Precision C10 Conductor anthracite]
[H5] PEtER Upsampling Spline Filter
Music is not experienced as data. It unfolds as attacks, decays, harmonics, and spatial cues, all dependent on precise timing. CH Precision’s objective in the C10 is exacting: faithful reconstruction of the musical event in space and time.
​
Every DAC must upsample and filter digital data to reconstruct a continuous analog waveform. In conventional digital design, those stages force compromises among frequency response, phase behavior, impulse response, and ringing suppression. Each choice reshapes the waveform in time. Even very expensive DACs often respond by offering multiple filters, asking the listener to choose a preferred compromise. CH Precision developed a different solution.
​
Waveform reconstruction in the C10 begins with the proprietary PEtER Upsampling Spline Filter. Developed entirely in-house, PEtER—Polynomial Equations to Enhance Resolution—restores the waveform’s natural curvature and continuity with far greater fidelity than conventional interpolation methods. It preserves each original sample value while sharply reducing the spurious energy introduced by traditional digital filters.
​
Pre- and post-ringing are essentially eliminated without phase distortion. Attacks emerge with greater clarity and immediacy. Decays unfold more naturally. Harmonic structures remain coherent. Low-level spatial information resolves with greater stability, dimensionality, and scale. Silence stays black because the waveform carries far less temporal smear.
​
By preserving the time domain with this degree of rigor, the C10 reproduces music with uncommon believability.
[IMG: CH C10 Anthracite-Edit.jpg]
[H5] Differential Conversion, Perfectly Controlled
The C10 Reference DAC’s DSQ™ Phase Array is built around sixteen precision R-2R resistor networks: eight per channel, with four handling the non-inverted signal and four the inverted counterpart. Each network is fabricated on a common silicon substrate, ensuring geometric and thermal consistency across all elements. This shared foundation minimizes the microscopic variations in spacing and temperature that can compromise linearity, preserving long-term stability and channel symmetry.
​
Within the array, each ladder is switched in a precisely controlled sequence to maintain balance, uniform current distribution, and dynamic consistency across the full conversion process. This disciplined management of the resistor networks suppresses the subtle mismatches that can generate harmonic distortion, noise modulation, and low-level instability in conventional R-2R implementations.
​
The conversion stage preserves the integrity of the signal from transient attack to final decay with exceptional precision and coherence. It is this combination of substrate-level uniformity, differential symmetry, and tightly controlled array behavior that defines the C10’s character: a digital source of uncommon resolution, stability, and naturalness.

[H5] Tailored for Your System.
Ready for What Comes Next.
The C10 Reference DAC’s modular architecture allows the digital front end to be configured around the needs of a given system, whether at the time of purchase or later as those needs evolve. Three identical input slots provide substantial flexibility. Every C10 comes equipped with CH Precision’s proprietary Digital Input HD board (DIG_HD_IN) as standard, leaving two additional slots available for expansion.
​
The C10 can be fitted with an optional Ethernet Streaming HD board for high-resolution playback from networked sources via UPnP or Roon, along with direct access to streaming services including Qobuz, TIDAL, and Internet radio. CH Precision’s proprietary streaming architecture preserves signal integrity, timing precision, and musical coherence through a fully integrated design. A dedicated USB board (USB_IN) can be added for USB audio playback. An optional Clock Board (CLOCK_SYNC) provides one clock input and two outputs via high-quality BNC connectors, enabling integration with external time references such as CH’s T10 Time Reference. The remaining slot may also be used for an additional Digital Input HD board when required.
​
These options allow the C10 to be specified with precision from the outset, then expanded later as system requirements evolve, without disrupting the integrity of its original architecture.
​
That same architecture reflects CH Precision’s long-term commitment to its customers. A C10 can be advanced all the way to full C10 Statement DAC specification with no price penalty, preserving both value and the confidence that a clear path remains open as ambition grows.
[IMG: CH Precision C10 Mono Anthracite Gradient.jpg]
[H5] The C10 Reference Mono DAC
The C10 Reference Mono DAC is a three-box system, with two dedicated DAC chassis and two independent external power supplies. Each channel is given its own complete conversion and power platform, extending CH Precision’s dual-mono architecture to its fullest expression.
The addition of the second power supply provides each channel greater isolation, lower noise, and freedom from the load-related interactions inherent in shared-power operation. With left and right channels fully separated in both signal path and power delivery, the electrical environment becomes more stable and less susceptible to interference.
The musical result is greater spatial precision, stronger image stability, finer dynamic shading, and more natural harmonic development. Bass gains grip and articulation. Low-level detail emerges more clearly. The entire presentation becomes more effortless, expansive, and resolved.
In mono configuration, the C10 Reference DAC realizes the full benefit of dedicated resources for each channel, bringing music forward with greater authority, coherence, and truth.

Every addition extends the C10’s inherent strengths while preserving the precision, stability, and musical coherence established by the DAC itself. The architecture remains additive, time-aligned, and continuous from the first C10 configuration to full C10 Statement DAC realization.

From its proprietary spline-based filter to its rigorously isolated power architecture, the C10 is engineered to preserve temporal integrity and reveal the expressive depth of recorded music. In a world of shifting formats and transient solutions, it is built to endure, to evolve, and to remain musically relevant for years to come.

[H2] C10 Statement DAC
[H5] A New Statement in Digital
Most high-end digital audio companies still refine architectures conceived in an earlier digital era. The C10 Statement DAC was created from a different premise: that believable digital reproduction depends not merely on low noise, linearity, or frequency accuracy, but on preserving the temporal relationships by which music becomes intelligible and real. Developed within CH Precision’s culture of invention, the C10 is the company’s flagship digital-to-analog converter—a purpose-built statement in digital waveform reconstruction, deterministic conversion, and time-domain fidelity.
​
The C10 consists of the Master DAC and the Conductor, each with a distinct function. The Master DAC performs the conversion itself, translating digital information into an analog signal with CH Precision’s most advanced conversion architecture, while the Conductor manages the processing, timing, and system control that allow that conversion to occur under more ideal conditions. This architecture galvanically isolates the most timing-critical digital and analog domains in distinct, independently powered chassis so that processing precision, conversion integrity, and analog purity can operate in electrically separate environments. Cross-domain interference is eliminated, temporal stability is enhanced, and musical structure is preserved more completely.
​
The C10 Statement DAC is CH Precision’s most advanced expression of what digital can become when clocking, upsampling, conversion, analog output, and power architecture are treated as a single coherent system.

The C10 Statement DAC begins from a conviction that defines CH Precision’s digital work: music is not perceived as an abstract spectrum, but as a sequence of events unfolding in time. Attacks, decays, harmonic bloom, spatial cues, and silence all depend on exact temporal relationships. Preserve those relationships, and instruments retain identity, body, and position in space. Disturb them, even subtly, and the illusion begins to weaken.
​
That is why CH Precision approaches digital reproduction differently from manufacturers whose design priorities remain centered on conventional steady-state measurements alone. The central problem is not simply how accurately amplitude is reconstructed, but how faithfully temporal information survives the entire conversion process. The C10 was engineered to preserve the ordered flow of musical events from input to analog output.
​
Rather than asking the listener to choose among familiar digital compromises, the C10 is built around proprietary solutions that address time-domain error at its origin. Its architecture reflects a more recent and more rigorous understanding of how waveform reconstruction, clock stability, deterministic conversion, and power behavior shape what we ultimately hear.

[H5] The C10 Conductor—PEtER Spline Upsampling Filters and the Art of Timing
In digital systems, upsampling and reconstruction filtering are the first stages at which musical timing is potentially altered. Traditional linear-phase filters preserve amplitude response, but generate symmetrical pre- and post-ringing around transients. Minimum-phase filters remove pre-ringing, but do so by introducing phase shift and frequency-dependent delay. Both approaches leave the designer managing side effects. Both reshape time.
​
CH Precision did not choose among those compromises. It developed a different solution.
​
Within the C10 Conductor, the proprietary PEtER spline filter—Polynomial Equations to Enhance Resolution—reconstructs the waveform by enforcing smooth continuity of slope and curvature between samples. Instead of forcing the signal through a conventional brick-wall model and then coping with the consequences, PEtER begins with waveform geometry itself. Its task is not merely to interpolate additional points, but to preserve the natural temporal shape of the event as it unfolds.
​
This reconstruction operates across PCM signals from 44.1 kHz to 768 kHz and DSD from 2.8224 MHz to 22.5792 MHz, with 32-bit internal precision providing the computational density required for spline-based waveform reconstruction. The musical consequence is profound. By essentially eliminating both pre- and post-ringing while maintaining mathematically correct reconstruction, the C10 preserves transient definition, harmonic settling, and low-level spatial information with exceptional coherence. Rhythm retains propulsion. Harmonics lock into place with greater naturalness. Silence remains cleaner, less agitated by the time smear that conventional filtering introduces.
​
This is not a selectable voicing option. It is the foundation of the C10’s behavior.

[H5] The C10 Master DAC—Determinstic R2R Conversion
Within the C10 Master DAC chassis, the C10 Statement DAC extends CH Precision’s deterministic philosophy into the conversion stage itself. Rather than relying on the delta-sigma architectures that dominate contemporary digital audio—with their extreme oversampling, noise shaping, and statistical averaging to approximate the desired analog output—the C10 uses a true multi-bit R-2R architecture, in which each digital code maps directly to a defined analog state. In CH Precision’s DSQ implementation, conversion occurs at full 24-bit data density at 2.8224 MHz, using eight precision DAC elements per channel in a synchronized phased array. This yields a level of deterministic data density substantially greater than that of even the most sophisticated delta-sigma DACs, allowing each switching event to be resolved explicitly in time rather than inferred statistically from a noise-shaped bitstream.
​
Music is not heard as an average. The ear evaluates each event as it arrives, moment by moment, by aligning transients, fundamentals, harmonics, and decay. When conversion itself becomes statistical—as in delta‑sigma systems—the waveform must be reconstructed from massive oversampling and noise‑shaped bitstreams, inevitably separating the mathematical representation from the instantaneous musical event. When those elements are rendered explicitly and coherently, music sounds more complete, more stable, and more believable.
​
At the center of the C10 is CH Precision’s DSQ Phased Array architecture, in which multiple precision R-2R conversion elements operate in parallel under the control of the same ultra-stable timebase. The key is not merely multiplicity, but synchronization. Every switching event is phase-aligned and algorithmically controlled so that summation increases precision without introducing time-domain blur.
These converter arrays are fabricated and mounted on a common substrate, ensuring shared thermal behavior, consistent geometry, and tightly controlled electrical conditions. This architecture delivers lower error, improved linearity, and greater low-level resolution while preserving the temporal explicitness that gives deterministic conversion its musical authority.
​
Here, CH Precision’s engineering discipline becomes audible. Harmonic structures settle with greater density and ease. Spatial images hold their position more convincingly. Microdynamic nuance emerges without edge, glare, or synthetic emphasis.

[H5] Time as System Architecture
The C10 Statement DAC is a unified flagship architecture built from the Master DAC and the Conductor, each with its own dedicated power supply. The purpose of this separation is fundamental. High-speed digital processing, timing control, and signal routing generate electrical activity that can compromise the delicacy of the analog conversion environment if housed too closely together. By assigning these functions to separate, independently powered chassis, the C10 galvanically isolates them, eliminating cross-domain interference and preserving a quieter, more stable context for conversion and analog output.
​
This is how CH Precision advances from an already extraordinary converter in the C10 Reference DAC to its statement digital platform: not by replacing the underlying philosophy, but by giving that philosophy a more ideal physical and electrical environment in which to operate. The architecture becomes calmer, more isolated, and more exact. Musical consequences follow naturally—greater low-level intelligibility, more stable imaging, more convincing decay, and a stronger sense of continuity through complex passages.
[H5] Where Time Is Governed
The success of a flagship DAC is not determined by conversion alone. Upsampling, clock generation, analog output, and energy delivery must all preserve the same temporal logic.
The C10 is governed by a purpose-engineered local master clock whose stability allows internal processing to remain anchored to a coherent time reference. CH Precision’s synchronous architecture prevents short-term disturbances from incoming signals from dictating the timing of conversion. Instead, the system’s own clock remains the dominant authority, maintaining the predictability on which musical coherence depends.
​
Following conversion, the analog stage preserves what the digital architecture has established. Fully discrete, Class A, and DC-coupled, it is designed to maintain speed, symmetry, and stability under real musical conditions. Transients recover cleanly. Harmonic relationships remain intact as levels rise and fall. The analog stage does not editorialize; it preserves.
​
Power supply design is treated with the same seriousness. In CH Precision’s architecture, power is inseparable from timing. The C10’s multiple chassis and isolated supply domains reduce interaction between clocking, digital processing, and analog output, ensuring that instantaneous musical demands do not disturb the very references on which precision depends. The result is not merely lower noise, but greater temporal stability under dynamic conditions.
​
Together, these disciplines allow the C10 to behave less like a chain of stages and more like a single time-coherent instrument.

[H5] The C10 Statement DAC Mono:
The Architecture of Total Power Separation
For those seeking the most complete realization of the platform, CH Precision offers the C10 Mono Statement DAC: an C10 configured with a second dedicated power supply. The purpose of that addition is not redundancy, but deeper isolation. By assigning still more narrowly defined electrical responsibilities to discrete supply domains, the C10 Mono further reduces interaction between critical circuits and preserves an even calmer operating environment for timing, conversion, and analog output.
​
In digital reproduction, this matters because power is never merely supportive. It shapes the stability of the references on which conversion depends. When those references are better protected from fluctuation, interference, and shared demand, the system behaves with greater poise and precision. Low-level information emerges more freely. Spatial relationships become more settled. Dynamic contrasts arrive with greater ease and less strain.
​
The C10 Mono Statement DAC is therefore not a different philosophy, but a deeper execution of the same one. It extends CH Precision’s commitment to separation, stability, and temporal integrity to its furthest expression, advancing the flagship platform through more complete electrical autonomy.
