CH Precision – 10 Series
SWITZERLAND · ULTRA HIGH-END AUDIO INSTRUMENTS · OFFICIAL SA DISTRIBUTOR

At CH Precision, precision is not simply a measure of performance; it is the principle that governs every decision, every technology, and every element of every design.
Every aspect of a CH Precision component is engineered in-house—from analog and digital circuitry to signal processing, streaming architecture, software, power supplies, and mechanical design. Rather than depend on off-the-shelf modules or outsourced platforms, we develop solutions expressly to advance believable music reproduction.
That same independence shapes our modular architecture. CH components are conceived as enduring platforms, able to evolve through hardware, firmware, and system expansion without rendering the original investment obsolete. It is not merely how we engineer. It is who we are.
Precision as Principle
CH Precision components are conceived not as fixed products, but as enduring platforms. Their modular architecture allows each component to evolve through hardware expansion, firmware refinement, and new system configurations, enabling listeners to deepen and refine their experience without abandoning their original investment.
This capacity for evolution is more than an architectural principle. It is the natural expression of a philosophy that unites invention, engineering discipline, and long-term respect for the listener.

C10 Statement Mono DAC
The Summit of CH Precision Digital Playback.
The C10 Statement Mono Digital System is the fullest expression of CH Precision’s digital architecture: a dual-mono Statement DAC platform conceived for systems where digital conversion is the central act of musical reconstruction.
Its foundation is engineering discipline. Every critical element has been developed in-house: digital processing, clocking strategy, conversion topology, analog output, power supply, mechanical structure, firmware, and control interface. Nothing outsourced. Nothing treated as generic. Each stage designed as part of a single coherent system whose purpose is to preserve timing, resolution, dynamic integrity, and musical continuity from input to output.
That discipline reflects a lineage unusually deep in digital audio. CH Precision’s core engineering team includes figures whose work helped shape modern high-end digital playback through advanced DAC design, sample-rate conversion, clock-domain management, digital filtering, and proprietary signal-processing. In the C10 Statement Mono, that experience is not presented as legacy. It is brought forward as architecture.
The Pinnacle of Digital Audio
As CH Precision’s ultimate digital front end, the C10 Statement Mono Digital System stands at the summit of the company’s work in digital playback. It gathers the full C10 architecture—PEtER spline-based reconstruction, DSQ R-2R conversion, channel-dedicated power, T10 reference timing, and, optionally, the D10 Reference Transport—into a single system conceived not as an assembly of components, but as a complete instrument for the preservation of musical time.
Its achievement is not one of scale alone, but of coherence. Each element serves the same governing purpose: to reduce uncertainty, preserve temporal integrity, and allow the musical event to emerge with its natural structure intact. Processing, conversion, power, clocking, and optional disc playback are not treated as separate acts, but as interdependent parts of a unified architecture.
That continuity reflects CH Precision’s larger modular ethos. Advancement is additive, disciplined, and structurally meaningful. Nothing is discarded for effect. Nothing is multiplied for spectacle. Each stage is elevated through greater isolation, deeper precision, and more exact control of the time domain.
The C10 Statement Mono Digital System is therefore both culmination and declaration: the fullest realization of CH Precision’s digital architecture, and a reference system built to preserve the temporal truth of music.

T10 Time Reference
Absolute Temporal Precision
Mastering the Moment
The T10’s performance begins with its extraordinary oscillator section. At its heart is a precision oven-controlled crystal oscillator (OCXO), encased in a massive solid aluminum block to ensure maximum thermal stability. This housing is further suspended on a bed of soft silicone gel, isolating it from mechanical vibration and environmental interference. The result is an internal timing core of exceptional consistency, critical for maintaining the ultra-low phase noise that defines the T10’s sonic contribution.
Where conventional word-clock systems rely on crystals cut to the 44.1 kHz or 48 kHz families, CH Precision takes a different path. The T10 generates a 10 MHz reference that is then divided down digitally, using an advanced all-digital PLL. This approach begins with a cleaner spectrum and produces measurably lower in-band jitter than “direct” audio-rate crystals, no matter how neat their integer relationships appear on paper. The result is not just mathematical accuracy but time-domain stability, exactly the quality to which the ear is most sensitive. Published data shows the T10 operating at femtosecond-level jitter (10⁻¹⁵ s), roughly 1,000× more precise than the picosecond-level performance typical of most competing designs. In practice, that translates into lower noise, sharper transients, and greater spatial coherence.
This precision extends to the T10’s output stage. Six individually buffered outputs are provided, each independently configurable to deliver either a 10 MHz sine or square wave signal at selectable 1 V or 500 mV peak-to-peak levels. These transformer-coupled outputs are routed through 75 Ω BNC coaxial connectors, a design that minimizes phase distortion and allows the T10 to synchronize multiple devices simultaneously without crosstalk or degradation. Unlike word-clock systems limited to distributing 44.1/48 kHz signals, the T10 can integrate an entire digital chain (whether a C10 Master DAC, D10 Reference Transport, or even third-party sources that accept a 10 MHz input) into one coherent time domain.

L10 Reference Line Preamplifier
Redefining the Reference: The Evolution of Precision
With the L1 Line Preamplifier, CH Precision set a new benchmark for musical transparency, realism, and control: a reference point that continues to define the category. To surpass it, the CH engineering team returned to first principles, drawing on decades of collective expertise to reimagine the Line Preamplifier from within.
The L10 Reference Line Preamplifier retains the essential architecture of its sibling: fully discrete, balanced circuitry, ultra-short signal paths, software-defined control, and advanced power regulation. But every element has been reassessed and refined. Signal paths are even shorter and cleaner. Every component, no matter how small, has been reconsidered and, where possible, improved. A new, purpose-built power supply delivers significantly greater regulation and storage. Feedback topology is now user-selectable, and proprietary software compensates for DC offset between connected components, pushing performance even further.
The result is not merely an evolution of the L1, but a redefinition of what a line preamplifier can be. With extraordinary resolution, a vanishingly low noise floor, and a more natural tonal balance, the L10 conveys the full expressive range of music with effortless command. Its emotional immediacy, spatial precision, and tonal realism bring recordings to life with uncanny presence. True to CH Precision’s design philosophy, it also offers extensive configurability, upgradeability to a four-chassis monaural topology, and a full-function control interface, delivering an experience as complete in execution as it is compelling in sound.

M10 Reference Power Amplifier
Power Refined. Precision Redefined.
Superseding a benchmark is never a small task, especially when that benchmark is the M1.1 Power Amplifier, a design that quickly earned its place as a modern reference in both power and versatility. With the M10 Reference Power Amplifier, CH Precision undertook not just an upgrade, but a reinvention: a ground-up reassessment of every circuit, every board layout, every material choice, and every performance parameter. The result is not merely a more powerful amplifier, but a fundamentally more revealing one. From a newly developed input stage to a reengineered signal path and a doubled power supply capacity, the M10 delivers extraordinary resolution at low levels, effortless headroom at the peaks, and a natural tonal continuity across the full dynamic range.
True to CH Precision’s design philosophy, it is also modular and upgradable (configurable as a stereo amplifier, a monobloc, or a fully bridged unit) designed to evolve with the system and the listener. Its ability to preserve spatial integrity, harmonic structure, and emotional intensity (regardless of scale) is not only technically astonishing, but musically transformative.
The Measure of Power
The M10 is more than a power amplifier—it is CH Precision’s vision of adaptable, precision-driven performance. Designed as a modular platform, it supports stereo, bridged, monobloc, and biamp configurations, all accessible without hardware changes or added cost. It evolves with your system, delivering power that is as refined as it is responsive.
Its dual-chassis architecture isolates the amplification stages from the power supply, minimizing noise while ensuring thermal stability and long-term composure. Twin 1800 VA transformers, supported by a carefully structured capacitor bank totaling approximately one farad (1,000,000 µF), deliver current with exceptional speed, control, and reserve. Adjustable global feedback—set in precise 1 percent increments—along with independent bi-amp calibration, allows the M10 to be tuned not only to the system it drives, but to the musical demands placed upon it.
The result is power shaped by precision: resolution, scale, and tonal realism delivered with absolute authority and emotional clarity.

P10 Reference Phono Preamplifier
The Vinyl Experience, Redefined
The P10 Reference Phono Preamplifier represents CH Precision’s most ambitious statement in vinyl playback: a phono stage conceived to stand beside the L10 Reference Line Stage and M10 Reference Power Amplifier as a definitive reference in analog reproduction. Building on the legacy of the P1, long regarded as a benchmark for adjustability and musical integrity, the P10 advances the state of the art technically, architecturally, and sonically.
Its twin-chassis design pairs a massive, dedicated power supply with a newly developed three-stage gain architecture that drives the noise floor to unprecedented lows while expanding dynamic, spatial, and tonal resolution. Four fully independent phono inputs (two trans-impedance current-sensing and two voltage-sensing MC/MM circuits) accommodate even the most complex analog front ends. Finer gain increments, user-selectable feedback structures, advanced loading options, and seven EQ curves allow each input to be matched precisely to your cartridge, record label, and system. From the refined control interface to the intelligent setup wizard, every element serves a single purpose: to reveal the full expressive potential embedded in the vinyl medium
