CH Precision M 1.1 (Certified Preowned) in box

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 demand 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 amplification.
What sets the M1.1 apart? It goes without saying that the 
M1.1’s sonic and musical performance challenges the state-of-the-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.
For a start, it’s not just one amplifier: it’s actually four 
amplifiers in one – at least in conceptual terms. The 
sophisticated software in the M1.1 allows the owner to 
configure the unit in one of four different ways. So, an M1.1 is 
a conventional stereo amplifier but it is also a high-current 
mono-bloc in which the entire power supply is devoted to a 
single output channel, a high-power, bridged-mode mono bloc and a bi-amp mode stereo unit in which a single input 
can be differently configured for the two output channels. 
Differently configured? Yes, because the M1.1 allows owners 
to select gain and percentage of global feedback for each 
channel independently – which means that the amplifier can 
be adjusted for overall system gain and noise performance, 
as well as configuring the low-frequency damping and gain 
to match system topology.
That means that the M1.1 is both configurable to specific 
speaker loads and inherently upgradeable – as well as 
adaptable to upgrades elsewhere in the system. Change 
your speakers or line-stage and the amplifier you already 
own will adapt to deliver the best possible performance. 
Start with a stereo amp and it can grow into a pair of monoblocs or a bi-amped system, all without having to replace 
existing units or even changing your interconnect cables. For 
once, the best sounding amplifier is also the sensible choice, 
because there’s finally an audio amplifier that’s got both 
finesse and brute force.
