Our take on the Anthem MCA 225

If you're looking for ways to improve your 2-channel listening, a high-quality stereo amplifier like the Anthem MCA 225 can make a powerful difference. Some people think that high-powered amps are only about playing your music louder, but there are other benefits. A well-designed amplifier can do a better job of controlling the stop-start motion of your speakers' drivers, enhancing virtually every aspect of sound quality from deep bass, to dynamics, to soundstaging.

Clean, clear sound and rock-solid reliability

If you're looking for ways to improve your 2-channel listening, a high-quality stereo amplifier like the Anthem MCA 225 can make a powerful difference. Some people think that high-powered amps are only about playing your music louder, but there are other benefits. A well-designed amplifier can do a better job of controlling the stop-start motion of your speakers' drivers, enhancing virtually every aspect of sound quality from deep bass, to dynamics, to soundstaging.

Usually power amps like the MCA 225 are paired with stereo preamps, or A/V preamp/processors like Anthem's superb AVM 60. But if your home theater receiver has preamp outputs — and many do — you can easily connect the MCA 225 and use it to drive your main left and right channels. That surge of added power does wonders for music and movie soundtracks.

Inside the Anthem sound

Anthem MCA 225 back

The MCA 225 has RCA and XLR inputs for use with a wide range of preamps and A/V preamp/processors.

The MCA 225's rated power output provides a clue to this amp's unshakeable grip on the music. It produces 225 watts per channel at 8 ohms, 400 watts into 4 ohms and an incredible 600 watts into 2 ohms!

Those numbers tell you that the MCA 225 has a very robust regulated power supply. I'm not actually aware of any 2-ohm speakers currently being made, but there are lots of high-performance 4-ohm speakers that would love to hook up with this Anthem.

When designing their latest MCA Series amplifiers, Anthem upgraded nearly every part in the signal path in order to reduce noise and distortion. From the custom high-power toroidal transformer inside, to the re-designed speaker binding posts in back, every feature was optimized so that you'll hear clean, transparent sound emerging from an eerily quiet background.

Crutchfield Customer Review (What's this?)

I tried 3 high quality amps to drive my Martin Logan Expression 13A electrostatics before settling on the Anthem MCA 225. Part of the Masterpiece series, the ML's each have twin internal 300W Class D amps to drive dual 10 inch woofers, so the Anthem only needs to drive the electrostatic panels, which are hardly an easy load. It does so effortlessly. Even heavily orchestrated musical passages contained in Mahler symphonies, with 100+ musicians blasting away, come across with great clarity. Instrument separation is terrific. The soundstage is incredibly large, present and realistic. Playing Bach's Toccata and Fugue in D minor turns my 14x20 room into a cathedral. The organ's low registers in particular would be felt by the neighbors were it not that I live in a condo with no shared walls. I no longer need to go to the Roosevelt Chapel at the University of Chicago to hear powerful organ music powerfully rendered. Coupled with the 851N Cambridge Audio network streamer, my rig is now everything I was hoping for and far more, for all kinds of music. Bohemian Rhapsody has never sounded to good. To say that I now enjoy a good 6 hours a day listening to music in retirement is probably an understatement. The Anthem amp made my $15,000 speaker investment worthwhile, even to my spouse. As high end amps go, its easy on the pocketbook. Many thanks to my Crutchfield adviser Allen. I trusted his recommendation on the Anthem MCA 225 and could not be happier.

Pros: Effortless, clear sound in simple arrangements or heavily orchestrated passages. Amazingly realistic sound. Tons of power for speakers who love it.

Cons: It doesn't even get hot. Is it on? I see the blue light so it must be.

I love this amplifier. Everything about it is quality. I'm using it with a Rogue Audio 99 pre amp and Klipsch Cornwall II speakers that I've had since the mid 80s. It sounds so good I never want to leave home again. Crutchfield was also great to order from and everything was as promised.

Pros: Beautiful component, awesome power, quiet, and relatively cool operation.

Cons: None

Awesome Amp

Crutchfield Customer Review (What's this?)

I am using this amp to drive my front speakers in my home theater set up and also for stereo listening. My main a/v receiver is certainly capable but lacked the punch I was looking for. This amp really made up the difference and then some!

Pros: Responsive amp with very tight bass notes and plenty of head room! Running a pair of Martin Logan ESL's (6 ohms) and there is plenty of pinch in this amp.

Cons: Minor - left and right inputs are about 15 inches away. Most high-end stereo cables restrict the width between the left and right cables. Ended up using two sub-woofer cables to run left and right side. This ultimately costs more to do.


Hands-on research

Product Research


MCA Series Amplifier: Anthem's MCA series of amplifiers balance the complex dynamics of today's most demanding multi-channel media with the rare finesse required to satisfy the audiophile in you. MCA series amplifiers provide an abundance of conservatively rated power into demanding low-impedance loads with incredible reliability.

Note: The MCA series amplifiers are perfectly matched for Anthem's AVM 60 Pre-Amplifier (973AVM60, sold separately).

Superior Craftsmanship: The Anthem MCA series multi-channel amplifier's superior craftsmanship is reflected in its clean, clear, audiophile-quality sound from top-to-bottom of the frequency spectrum. MCA series multi-channel amplifiers utilize only the highest quality of parts - like 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.

Stereo Power Amp: The Anthem MCA 225 stereo power amplifier is incredibly stable into difficult, low-impedance speaker loads, making it a reliable performer in even the toughest circumstances. The MCA 225 utilizes 8 bipolar output devices per channel for greater high-current power with less stress on the amplifier.

  • 8Ω: 225 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)
  • 4Ω: 400 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)
  • 2Ω: 600 watts per channel (continuous RMS, 20Hz to 20kHz, <1% THD)

Massive Toroidal Power Supplies: MCA series amplifiers deliver incredible dynamics thanks to massive, 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 theater and the most complex and dynamic music recordings.

Direct Path Circuitry: The  MCA series greatly reduces the use of internal cabling for a much smoother circuit path for pure, unobstructed audio performance. Both power supply impedance and internal cabling inductance have been minimized to deliver a direct, clear path for maximum power; even in the most demanding conditions. Consequently, Anthem 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.

Advanced Load Monitoring (ALM) Technology: Anthem's exclusive ALM circuitry protects the amplifier's sensitive output devices by constantly monitoring temperature, current, and voltage to ensure optimum long-term performance. ALM is totally non-invasive; it is not in the signal path and only engages in the most extreme circumstances to protect the amplifier from damage by maintaining the safe operating area of the output devices.

120dB Signal-To-Noise Ratio: With a signal-to-noise ratio of 120dB, background noise is practically nonexistent, leaving you with just pure natural sound reproduction from the MCA series amplifier.

Balanced & Unbalanced Analog Inputs: The Anthem MCA 225 amplifier is equipped with one balanced stereo XLR input and one unbalanced stereo RCA input. Balanced XLR connections offer the highest transmission quality, particularly over long cable lengths, because they reject noise and hum pickup. If your preamplifier does not have XLR outputs, use the RCA inputs.

Custom-Designed Binding-Posts: Custom-designed, oversized robust binding-posts ensure full power delivery at all times. They're easy to use and facilitate large speaker cable connectors, as well a banana plugs (single only).

Trigger Input/Output: The Anthem MCA 225 is equipped with a 12V trigger input (3.5mm) and 12V trigger output (3.5m) to synchronize power on/off with other components that also feature 12V trigger inputs and outputs.

3-Way On/Off: The MCA series amplifier can be powered on or off in three ways - manually with the On/Off switch on the front-panel, remotely via the rear-panel 5V-24V trigger input, or automatically with Anthem's patented Auto-On/Off circuit. Via the Auto-On/Off circuit, an incoming audio signal immediately switches it on; and approximately 20 minutes after the audio signal ends, it simply switches off.

Protection Circuitry: The Anthem MCA series amplifier utilizes a 3-way protection circuit to guard against Short Circuits (Short Circuit protection), Over-Heating (Thermal protection), and Ground Faults (DC protection).

Crafted In Canada: Anthem's MCA series multi-channel amplifiers are designed and crafted in Canada.

No.... [ Jesse  Feb 05, 2018 ]
No , there is no headphone jack - have it tied in as a secondary two channel power amp [ Alan  Feb 05, 2018 ]
No. Headphone jacks belong on the pre-amp/pre-pro, or on a stand-alone headphone amp that attaches to non-volume controlled audio-outs on the pre-amp. [ Robin  Feb 03, 2018 ]
There is not. I have one on my preamp, but the power amp doesn't have one. [ James V.  Feb 03, 2018 ]
Hey, the headphone jack is on you pre-amp/home theater processor.... This is a power amplifier [ JASON D  Feb 03, 2018 ]
