Product Description

The latest Anthem MCA225 is a superb Stereo Amplifer has been completely redesigned from the ground up. Come and hear what all the fuss is about.


To complement the new Anthem AVM 60 A/V Processor and MRX Receivers, Anthem introduces the new MCA 225; 325 and 525 multi-channel power amplifiers that feature more robust and efficient power and heavy-duty reliability. The MCA Series delivers lower THD (total harmonic distortion) for more clean, pure sound and lower noise for a supremely quiet background.

Like all Anthem products these superb power amplifiers are designed and Crafted in Canada and because the Canadian "Looney" (C$) is almost on par with the Aussie dollar, you  get great value for money. Features include custom low noise high-power toroidal transformers; high-current bipolar output transistors; high-quality filter capacitors; advanced power supply regulators; oversized aluminum heatsinks; custom-designed dual binding posts; and patented auto-on/off circuitry. Superior craftsmanship that is reflected in clean, clear, audiophile-quality sound from top to bottom of the frequency spectrum.

Completely Redesigned: The latest MCA series greatly reduces the use of internal cabling for a much smoother circuit path for pure, unobstructed audio performance. The use of low-flux toroidal transformers and improved input transistors provide a greater sense of transparency, even with dynamically complex material.

The engineers have also improved other performance benchmarks including power bandwidth and slew rate. With a signal-to-noise ratio of 120 dB, background noise is practically nonexistent, leaving you with just pure natural sound reproduction.

Higher Power Into More Demanding Loads: Experience the immense dynamics of up to 600 clean Watts delivered into demanding 2-Ohm loads. Both power supply impedance and internal cabling inductance have been minimised to deliver a clear path for maximum power – even in the most demanding conditions. While previous 2-channel MCA amps used a single power supply for front left and right channels and another power supply of the centre and surround, the new MCA225 shares its two power supply between all channels. The result is full bursts of power – instantly – without affecting channel separation.

Next generation Advanced Load Monitoring Technology: Exclusive ALM™ technology monitors internal temperature, current and voltage to ensure safe and uninterrupted longterm operation, all the while eliminating the need for internal fuses. ALM™ is not in the signal path, so it never gets in the way. Instead, ALM engages instantly, but only in the most extreme circumstances, to protect your amplifier (and speakers) from damage. This new generation ALM™ lowers the chance of a line fuse blowing during an over-current condition. Should a fault condition arise, unaffected channels continue to play and all-channel operation resumes automatically once conditions are back to normal. The LED on the front panel confirms status at all times.

Engineered for Reliability: The new generation of MCA Amplifiers use Anthem’s years of experience to “engineer out” common amplifier gremlins. Consequently, they’ve removed output relays, so the signal path has absolutely no moving parts. All parts, including the eight bipolar output transistors per channel, are run conservatively so they remain within their safe operating range. Power-on inrush current has been minimised to reduce line disturbances and stress on internal components. They’ve also upgraded internal connectors and increased mechanical strength.

Green “Standby” Power Consumption: In addition to the reduced inrush current, the MCA225 Power Amplifier only uses 1 Watt in “standby” mode. As with all Anthem amplifiers, it can be switched on manually, via trigger, or by sensing an input signal. New, larger, more conductive audiophile speaker wire binding posts have been added to maximise contact and maintain a firm grip on the speaker cable. If you’re in the market for cutting-edge audio component separates, Anthem’s MCA225 balances the complex dynamics of today’s most demanding multi-channel media with the rare finesse required to satisfy the audiophile in you. The MCA225 provides an abundance of conservatively rated power into demanding low impedance loads, incredible reliability and a new design aesthetic that matches the stylish AVM 60 Pre-Amplifier.

Massive Toroidal Power Supplies: Last but not least the MCA225 delivers incredible dynamics thanks to massive “audiophile approved” conservatively rated power supplies designed with high rail voltages. Low flux toroidal power transformers ensure ultra quiet performance by minimizing stray magnetic field radiation. This provides the pure, clean, low-noise power that is needed to reproduce the full dynamics of home theatre and the most complex and dynamic music recordings.

Our Take

The 225 can be used as part of an up-market stereo or multi-room system although probably a little overkill for the latter. One other idea is to use your Home Theatre Receiver as the processor with the built-in amplifiers running the centre and effects speakers and maybe speakers in a second zone, however there are other and possibly better alternatives in that area. Afterall you'll be considering laying down some hard-earned cash to buy one of these babies so you'll want the rears etc performing at their max. If you have a really good pair of stereo speakers and 'must' have the best for music reproduction, then a 225 can run the main front speakers on all source material. What the 225' will do is give you more control and well over 200 genuine Watts per channel with short bursts upto 600 Watts when the impedance curve drops to 2 Ohms. That's just what you need to hear your music or movie sound track with the dynamics that are available.
