EX-DEMO - M1.1 STEREO POWER AMP

A wonderful opportunity to acquire our cared for Ex-Demonstration M1.1.

 

Having only been used in our private demonstration room within a full CH Precision system, the Amplifier presents in excellent condition and comes with its original box and accessories. 

​

This is a new spec M1.1 (not an upgraded older model).

​

It's partnering CH Precision L1 Pre- Amplifier is also available - Please contact the team for further information.

 

The M1.1 Power Amplifier builds on the legacy of CH Precision’s original M1, introducing circuit refinements, enhanced power management, and software-driven control that elevate its performance to new heights of musical transparency, dynamic authority, and stability under any loudspeaker load. Its fully discrete, complementary architecture with ExactBias™ real‑time bias control ensures vanishing distortion and effortless resolution, while its massive, ultra‑stable power supply and mechanically inert chassis provide the foundation for unshakable performance.

​

Equally impressive is the M1.1’s ability to evolve with your system. Its modular, software‑driven topology allows the amplifier to operate as a stereo amplifier, a high‑current mono‑bloc, a high‑power bridged mono‑bloc, or in vertical bi‑amp mode. In its mono and bi‑amp configurations, the M1.1 offers independent control of gain and global feedback per channel, enabling precise tuning for speaker load, low‑frequency damping, and system gain. This flexibility ensures that the M1.1 can adapt seamlessly to system changes—growing from stereo to mono or bi‑amp configurations—while preserving the reference‑grade performance that defines CH Precision.

The Art of Effortless Power

​

At the heart of the M1.1 Power Amplifier is an architecture conceived to deliver absolute authority without sacrificing musical finesse. Its foundation is a massive, ultra-low-noise linear power supply, anchored by an oversized high-current transformer and proprietary capacitors engineered for extreme time-domain accuracy. This immense energy reserve ensures that the M1.1 responds instantly to the most demanding musical passages, maintaining composure and control even under punishing dynamic swings. Mechanical grounding and ultra-short, optimized signal paths further protect the signal from noise and vibration, preserving the amplifier’s purity from input to output.

​

The fully discrete, complementary output stage reflects CH Precision’s flagship approach to wide‑bandwidth, high‑slew‑rate design. Operated in Class AB and carefully biased for exceptional linearity, the M1.1 delivers staggering current drive with vanishingly low distortion and noise. Yet its design is about more than sheer power: instantaneous current delivery combines with speed and agility, allowing the amplifier to reveal micro‑level textures, lifelike transients, and the harmonic richness that makes music feel three‑dimensional and alive. In the M1.1, power serves the music, rendering dynamic swings with unshakable authority while letting delicate details bloom effortlessly.

​

Like every CH Precision amplifier, the M1.1 offers adjustable local and global feedback, allowing the listener to fine‑tune the damping factor to match their loudspeakers and acoustic environment. Feedback is adjustable in 10% increments, shaping low‑frequency control, transient behavior, and overall system voicing for perfect synergy. In stereo mode, feedback and input sensitivity remain identical for both channels, while in monobloc or bi‑amp configurations, channels can be optimized independently—ideal for tailoring differential damping between, for example, a passive subwoofer and a main loudspeaker. This flexibility transforms the M1.1 from a powerhouse into a precision instrument, capable of integrating seamlessly into the most ambitious high‑end systems.
