Anthem Statement M1 Monaural Class D Amplifier

"An unreserved success at the cutting edge of amplifier design. It delivers stunning clarity, excellent dynamics and frankly frightening power in a form factor that is practical and energy efficient." Richard Stevenson, Hi Fi News UK

The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 Hz to 20 kHz.

HIGHEST SOUND QUALITY AT ALL VOLUME LEVELS, FLAT FREQUENCY
RESPONSE INTO ANY LOAD, STABLE INTO THE MOST DIFFICULT LOADS

The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 Hz to 20 kHz. It was designed and engineered in our advanced research center in Ottawa, Canada and is manufactured in our Toronto, Canada factory.

More than just a slim, technologically advanced monaural design, the M1 demonstrates that Class D architecture isn't fundamentally flawed, it simply hasn't been implemented well in the past, mainly because it required such a heavy commitment to R&D. We’re fortunate to have the in-house resources to create such a groundbreaking product and one listen will reveal the truly extraordinary nature of this amplifier.

WHAT WERE THE DESIGN PARAMETERS?

• Full resolution of all of the sonic subtleties and complexities in the input signal.
• Accurate reproduction of the full dynamic range of the signal
• Output stage is never allowed to clip
• No compression as output increases
• Flat frequency response into any load, without having to resort to digital conversion or equalization to compensate
• Stable into all loads including open circuit and short circuit
• A low noise floor
• Exceptional efficiency with low heat output
• An amp so mechanically silent it will suit even the quietest listening room
• A design that allows multiple units to be stacked with no danger of overheating
• All of the above delivered at a price point that while not inexpensive, delivers virtually limitless dynamic fidelity!

WHAT MAKES THE M1 THE BEST VALUE IN THE MARKET?  POWER!
2,400W into 3 ohms
2,000W into 4 ohms
1,000W into 8 ohms

These figures are continuous from 20 Hz to 20 kHz at less than 0.1% THD+N. The M1 can deliver 2 kW continuously when fed by 240V mains and 2 kW for several seconds when fed by a dedicated 120V 15A line.

The M1 enjoys all of the attributes of our award-winning Statement Class AB amplifiers but through exclusive Anthem technologies, goes far beyond the current capabilities of Class A, Class AB and prior Class D amplifiers in the market.
The proprietary design employs all of the advantages of a Class D amplifier — high output, high efficiency, compact size — while avoiding the typical Class D limitations such as difficulty driving low-impedance (high-end) speakers, power line contamination, reliability issues and substandard
audio quality.

The absence of accurate dynamics is so common that it frequently goes unnoticed, but through the M1, music and movies are delivered with breathtaking realism.
 

Anthem Statement M1 Monaural Class D Amplifier Reviews

Hi Fi News UK - by Richard Stevenson & Paul Miller (Lab) - Jan 2012
Anthem’s M1 is an unreserved success at the cutting edge of amplifier design. It delivers stunning clarity, excellent dynamics and frankly frightening power in a form factor that is practical and energy efficient.

Bass maybe a little dry for tube aficionados, poor recordings get merciless shrift, but the M1 has the ability to thrill with any genre of music. It punches way above its weight in every respect.

I would go so far to say that if you feed the M1s an immaculately mastered and well recorded tune, they will deliver power, precision and articulation like precious few power amps at the price.

The M1s crafted this two minutes of magic into an utterly sublime listening experience that reminded me exactly why I love music and hi-fi so much in the first place. ... I was head to toe in goose bumps, eyes closed, lost in the music.

This is by some margin the most powerful Class D amplifier we’ve featured in Hi-Fi News. B&O’s ICEPower1000 modules are rated at 1000W/4ohm but Anthem’s M1 succeeds in delivering 1.1kW/8ohm under dynamic and continuous conditions, a feat that swells to 2.08kW into 4ohm and 2.7kW/2ohm before its protection circuit activates.
