M10 Reference Power Amplifier

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.

At the heart of the M10 Reference Power Amplifier lies a reimagined amplifier architecture—one that fuses massive power with uncommon finesse. Its output stage topology is unlike any seen before: built around progressively smaller banks of capacitors the power supply is engineered not only for scale but for speed. By subdividing the energy reservoir into finely graduated sections CH Precision ensures that the amplifier can respond instantly to dynamic shifts maintaining low output impedance while supplying current with exceptional accuracy. The result is startling control over the loudspeaker even in the most delicate musical passages and an uncanny ability to preserve low-level detail tonal nuance and spatial coherence across the full dynamic range.

This precision is further extended by software-defined control. The M10 allows users to fine-tune global feedback in 1% increments ranging from 0% to 100% giving system builders the rare ability to adjust the damping factor to suit the loudspeakers room acoustics or musical material. In bi-amplified systems this control becomes even more meaningful: each channel can be set independently allowing for perfect optimization of high- and low-frequency drivers matching the amplifier’s behavior to the specific demands of the loudspeaker’s architecture. Whether configured as a stereo amplifier a monobloc or in bi-amp mode the M10’s topology and software act in concert to deliver an experience that is both musically transparent and system-aware offering not just raw power but the intelligence and agility to shape it.

In the M10 the power supply is not merely functional it is foundational. Designed around twin 1800 VAC transformers and a carefully structured capacitor bank totaling approximately 1 farad (1,000,000 µF) the supply delivers current with exceptional speed scale and composure. By distributing energy across progressively smaller banks the M10 ensures not only vast reserves but instantaneous responsiveness. This structure minimizes impedance reduces strain on any one section and allows the amplifier to maintain tonal balance and dynamic integrity even under the most demanding musical passages.​

The result is a sonic presentation that is as grounded as it is expressive. Notes emerge with clarity and weight silence has presence and space is carved with unshakable stability. This is power that moves with intention: unforced adaptive and inseparably tied to the music it serves.

The M10 incorporates ExactBias™ CH Precision’s proprietary dual-stage bias control system ensuring that its powerful output stage operates at peak linearity under all conditions. Conventional regulation monitors only the slow delayed temperature changes of the heatsink correcting bias long after the output devices themselves have drifted. ExactBias™ takes a fundamentally different approach: it measures the internal temperature of each output transistor directly using integrated sensing elements on the same silicon substrate.​

By tracking both static and dynamic thermal variations in real-time the system maintains a constant operating bias regardless of the program level or load. The output devices remain locked at their intended operating point whether idling quietly or delivering sustained current into the most demanding loudspeakers. With bias held stable to within a fraction of a percent crossover distortion is minimized dynamics flow naturally and the amplifier tracks the input signal with unwavering precision. The result is an effortless sense of proportion coherence and musical conviction—the unmistakable signature of the M10.

At CH Precision performance is never a fixed point. From its inception the M10 was designed as a modular platform—one that adapts to evolving systems ambitions and understanding. Its architecture supports a culture of upgrade not by replacement but by refinement: a continuous invitation to push the boundaries of what’s possible without discarding what’s already been achieved.

The M10 can be configured as a high-performance stereo amplifier set in biamp mode for enhanced control across frequency bands used as a dedicated monobloc or fully bridged for maximum output and authority. Each configuration unlocks new dimensions of resolution headroom and system synergy. And because these modes are supported within the same chassis and control architecture the path from one iteration to the next is seamless without modification recalibration or hidden cost.

This is amplification as an evolving craft: shaped by your loudspeakers your room your musical preferences and your aspirations. With each iteration the M10 becomes increasingly fine-tuned to its context delivering not just greater capability but also deeper musical understanding. It’s not just built to last. It’s built to grow.

Available for Apple iOS and Android the CH Controller provides complete app-based control of CH Precision systems including input selection volume mute configuration settings and playback functions. It also allows users to access UPnP devices on the network and browse the music stored there bringing system control and local music access into a single interface.​

Its structure follows the same operational logic as the componentsthemselves preserving a direct relationship between front-panel control and the mobile experience. True to CH Precision’s engineering culture the control platform is designed as an extension of the component architecture rather than a separate control layer. It adds convenience and flexibility while preserving the integrity precision and musical priorities that define every CH Precision system.
