The M 200 mono power amplifier has been developed with the sole aim of providing the ultimate in audiophile quality and performance – without any compromise or limitation. To this end the M 200 combines the fine detail, resolution and detail dynamics of our hugely esteemed A 200 stereo power amplifier with an output of more than 400 Watt. The M 200 is designed to feed just one loudspeaker, and this allows it to celebrate music in a manner which is even more audiophile, even more powerful and even more devoid of coloration than would ever be possible with a stereo power amplifier.
Its heatsinks are a technical necessity, but they are also more than that: at a single glance the innate power of this compact output stage is self-evident; naturally the heatsinks also ensure optimum heat dissipation – even under extreme load. The M 200 mono power amplifier is the most potent final stage in any system configuration: either as a complement to an existing system, or – in combination with the Series 200 – as the pinnacle of a perfectly compatible chain of specialised audiophile devices.
In our opinion power is only a positive factor if it goes hand in hand with the highest possible sound quality, efficiency and precision. That is why the M 200 shares a large number of the technologies employed in its sister device: the A 200. At its core there is a completely new circuit topology which attains the optimum blend of efficiency, performance and sound quality by combining our unique HV and High-Frequency Sine-Wave mains section technologies with PURIFI Eigentakt™ power amplifier technology. This combination is crucial to obtaining maximum audiophile performance from unrestrained power. In contrast to the A 200, the M 200 does not need to share this technology between two loudspeakers; instead it delivers its performance uniquely and alone to a single speaker. This again helps to maximise the potential of the A 200. If particular loudspeakers require a warmer or softer sound image, it is possible to reduce the M 200’s very high damping factor.
The output stages of the M 200 are Class D power amplifiers based on PURIFI Eigentakt™ technology. This platform, developed by the Danish technology company, is currently the world’s leading concept for Class D power amplifiers, and avoids the disadvantages of earlier digital amplifiers. Previous digital amplifier designs were limited by being very load-dependent, and susceptible to the impedance of the loudspeakers in use, generating distortion in the output signal, phase noise and increased harmonic distortion at high power levels. In contrast, this new concept produces outstanding measured results, and is predestined for use in audiophile equipment:
- Extremely low harmonic distortion and intermodulation effects at all power levels
- Extremely low noise
- High damping factor
- Clean clipping
- Low losses, high efficiency
- Linear frequency response up to 60 kHz
- Completely consistent behaviour, regardless of load (see graphs for 4 + 8 Ohms)
