Anthem M1

Description

The Anthem 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. Designed and engineered in their advanced research center in Ottawa, Canada, the M1 is manufactured in their Toronto facility.

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.

It’s cutting edge tehcnology includes:
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.

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.

The M1 is not a digital amp! There are no A/D or D/A converters in the signal path. The amplifier’s control system continuously varies the width of the output pulse train in direct relation to the analog input signal. In essence, a side-to-side variation in width is analogous to a signal’s more familiar up-and-down amplitude variation, not at all the same as a digital string of 1s and 0s where all pulses have the same width.

When rack-mounted, the 20-kb M1 occupies only one rack space but despite its size can deliver 1,000W into 8 ohms and 2,000W into 4 ohms. The M1’s cooling system quickly and efficiently moves heat from the interior of the amplifier to exterior heat sinks. Sealed copper pipes within the amp contain a small amount of special fluid held under a vacuum. When the temperature at one end of the pipe rises — the end adjacent to the amplifier’s heat sources — the fluid in that end evaporates. This vapor is then naturally drawn to the cooler end of the pipe, along the heat sink on the side of the amp’s chassis where it condenses. From there a copper wick returns the fluid to the hotter end of the pipe. This heat transfer process is many thousands of times faster and more efficient than cooling through metal heat sinks alone. This system eliminates the need for fans, allowing multiple M1s to be stacked with no danger of overheating. It also means the amplifier is so mechanically quiet it will suit even the quietest listening rooms.
