M10 Reference Power Amplifier
Power Refined. Precision Redefined.
Power, Structured for Precision
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.
Silent Strength. Perfect Control.
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.
ExactBias™—Stability at its Core
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.
Precision That Evolves
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.

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.
