Anthem Statement M1 Class D Amplifier

Anthem, is now shipping their new Anthem Statement M1 1000 watt Class D amplifier. Anthem claims that their M1 monaural amplifier makes radical improvements over current Class D amplifier designs, while maintaining the Class D design benefits.

The M1 utilizes a heat pipe cooling system and deep side-mounted heat sinks, which allow multiple M1s to be rack-mounted directly on one another, each occupying only a single rack unit. Since the M1 is also fan-less it is well-suited for the quietest of listening rooms.

Though the Statement M1 is a Class D design, it is not a digital amplifier. While Anthem’s own Statement P5, for example, outputs 500 watts with a 4-ohm load, the M1 delivers 2,000 watts to the same speaker, with total harmonic distortion remaining under 0.1% from 20 Hz to 20 kHz. (Into 8 ohms, it delivers 1000 watts with a less than 0.06% total harmonic distortion.) And frequency response is load-independent, so the difference in response between a 2-ohm load and an open circuit is an astounding 0.1 dB at 20 kHz. Between 4 ohms and 8 ohms there is absolutely no change in frequency response.

The Statement M1 attains this level of power, performance, and consistency through the employment of a few key technologies, including a proprietary load monitoring system that relies on a Digital Signal Processor—outside the signal path!—to monitor line voltage, output current, ground fault detection, temperature, and DC voltage at the output to ensure the highest possible output from either a 120V or 240V circuit. Power Factor Correction maximizes available power by marrying the voltage and current cycles, enabling continuous output from the power supply through the entire AC cycle without contaminating the AC line with noise.

While all of this innovation adds up to an amplifier that is admittedly not inexpensive, the Anthem Statement M1 nonetheless represents an unparalleled value in terms of price versus performance, with ample headroom to drive even the most power-hungry speakers, and the utmost in clarity and focus demanded by the most discerning listeners.

The Anthem Statement M1 is shipping now, with a MRSP of $3,499 U.S. and $3,799 CDN. More information can be found at:
