The CH Precision M 1.1 has been the darling of the press community and rightfully so.
There is no comparison to other products. Here is what several people comment on this delightful amplifier.

Product Description

The problem is that although power amps themselves might appear
simple, their job is anything but straightforward. Caught in a sandwich
between the output of a line-stage or DAC and the load requirements and
sensitivity of any number of different loudspeakers, they must be able
to accommodate the widest range of partnering equipment and interface
parameters presented to any unit in the audio system. Achieving optimum
results under such varied conditions demands a capable and versatile
performer – yet as we’ve already established, most power amps offer a
single, brute force solution to the problems they face, instead of
adopting a more sophisticated response. It’s time for a change – it’s
time to meet the CH Precision M1.1, a new-paradigm in power

What sets the M1.1 apart? It goes without saying that the M1.1’s
sonic and musical performance challenges the state-ofthe- art, an
incredibly short audio signal path executed with exacting component
choices and construction, a massive power supply providing absolute
stability and unfettered headroom, capable of meeting both the most
delicate and most massive musical demands. But what makes the M1.1
really different is its software driven housekeeping capabilities, a
non-intrusive support network that does more than just keep the
amplifier unconditionally stable.

Physical And Conceptual Modularity

  • Modular input boards to match system topology
  • Output stage can deliver 200W RMS into 8 Ohms stereo, 200W mono
    (high-current), 700W mono (bridged) or 200W bi-amped (single input,
    differential channel gain and global feedback settings)

Analog Input Stage

  • Pure class A, fully symmetrical circuit topology
  • Fully discrete, ultra low noise, high slew rate design
  • DC coupled with no series capacitors in the audio signal path

Analog Output Stage

  • Pure class A ultra low noise driver and class AB pure follower power stage
  • Patented ExactBias circuitry ensures constant bias, independent of
    room temperature. Monitors output power, temperature and amplifier
  • User configurable display will show amplifier status, power output etc
  • Customized Argento internal wiring and loudspeaker binding posts (accept spades or banana plugs)

Power Supply

  • 2200VA power transformer mounted on separate, mechanically isolated chassis bed to eliminate mechanical vibration
  • Magnetically and electrostatically shielded transformers to reduce noise and EM interference
  • Hyper fast, soft recovery diode bridge rectifiers meet dynamic demands without strain
  • Total of 250,000uF custom-built, ultra low ESR reservoir and filtering capacitors

User Adjustable Global Feedback Ratio

  • Ratio of Global to Local Feedback can be adjusted from 0% to 100%, in 10% steps via the user interface or control app
  • Allows user optimization of amplifier/speaker interface, especially low frequency damping relative to speaker/room interaction
  • Each channel can be adjusted individually to control specific drivers/ranges in bi-amplification modes

User Adjustable Input Gain

  • Input gain can be user adjusted to accommodate input signal level and overall system gain 24dB range in 0.5dB steps
  • Optimizes system noise floor and dynamic range
  • Accommodates variations in loudspeaker sensitivity and room size

Light Touch Protection

  • No output relay in signal path; full short circuit protection
  • Non-invasive output stage voltage, current and temperature monitoring protects your amplifier – and your speakers.

Some of our awards

“The M1.1 power amp is simply the most musically
accomplished, high-powered solid-state piece it has been my pleasure to
use. I love its configurable nature and I love the idea of adding
additional amps along the way.”
