Anthem MCA 325 Power Amplifier

Our design for MCA amplifiers follows the “Keep-It-Simple” principle. We utilize the fewest possible number of parts in the signal path to maintain the integrity of sound. All parts are of the highest quality and tolerance. These remarkable amplifiers offer the profound sense of musical purity, transparency and naturalness demanded by the most discerning listener.    

Solid state amplifiers get their power from the output devices used in the amplification stage. Just like cylinders in a car’s engine, the greater the number of devices per channel, the greater the available high-current power for the crescendos in music, or the thrills, thunder and explosions in movies. Performance is simply more effortless. It also means that the amplifier will run cooler, making it more reliable.  
Frequency response channel-matching in our amplifiers has always been far better than the norm. In fact, MCA amplifiers are virtually mirrorimaged. All amplifier channels offer identical performance. The musical picture is incredibly vivid, seamless, and detailed, with a multichannel soundstage that is exceptionally clear, coherent and three-dimensional. 

Each amplifier channel is completely self-contained on its own board and heatsink. In the rare event that service should be required, it can be done quickly and easily by a qualified technician, minimizing the “down time” of your system.   

In a rare feat, transformer-induced noise at the bass frequencies of 60 Hz, 120 Hz, and 180 Hz, has effectively been eliminated. MCA amplifiers boast vanishing noise and unbelievably low levels of Total Harmonic Distortion.   
Signal-to-noise ratio in MCA amplifiers is 120 dB … a truly remarkable feat! Music and movie soundtracks simply appear out of “dead” silence allowing you to become lost in the emotion of the original performance —the mark (and the end goal) of a truly high-end audio-video component. During even the most tranquil musical passages or dramatically quiet moments in a movie, the background is so ‘black’ that it is audibly gone. 
MCA amplifiers deliver incredible dynamics thanks to massive “audiophileapproved” conservatively rated power supplies designed with high rail voltages. Advanced-generation toroidal power transformers ensure ultraquiet 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. 

Our amplifiers are incredibly stable into difficult, low-impedance speaker loads, making these superb-sounding dynamos reliable performers in even the toughest circumstances   
Gold-plated female RCA jacks provide a high-quality input connection. XLR balanced connections are commonly used in professional recording and broadcasting to ensure the lowest level of noise and hum possible. Now you can use this same high-quality connection for reference-quality highend sound since XLR balanced inputs are included on all MCA amplifiers. Our unique auto-sensing technology makes connecting inputs a snap. Plug in either the RCA or XLR connector and the technology automatically selects the right input. 
More Power! More space to store it! With 225 watts, large banks of capacitors are needed to store all of the energy required for the immense dynamic bursts of various special effects in a movie, or the taxing crescendo of a solo piano. These amplifiers are the most powerful MCA amplifiers yet, employing 16,400 micro farads (μF) of capacitance per channel (that’s over 80,000 μF for the MCA 50). With so many joules of energy in reserve, when called upon, the MCA 20, MCA 30 and MCA 50 are able to deliver full bursts of power instantly and effortlessly.   
A redesigned chassis and large custom heatsinks—33% larger than previous MCA Series amplifiers—ensure that these amplifiers dissipate the heat generated by their higher power levels quickly and efficiently. Our custom heatsinks are computer-designed and modeled to maximize contact area for exceptional heat transfer efficiency. Put simply, they run cooler for greater reliability. 
MCA amplifiers can be powered On/Off three ways: manually with the On/Off switch on the front panel; remotely via the 12-volt trigger input on the rear; or automatically, with our patented 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. 

Our own custom-designed, oversized robust binding posts ensure full power delivery at all times. They’re easy to use and facilitate large speaker cable connectors.   
While a detachable AC power cord comes in handy when connecting various components, its function is more than one of simple convenience. High-end products typically offer the freedom to use a variety of aftermarket power cords offered by specialty cable manufacturers. By including IEC detachable AC female sockets and high-power, high-quality 14-awg AC cords, MCA amplifiers further demonstrate their high-end pedigree. 
Like all Anthem products the MCA 20, MCA 30 and MCA 50, designed and built in North America, are like no other amplifiers in the world: 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

In conjunction with Hitachi Capital we have sourced a range of finance plans to suit everyone. This can be offered for purchases over £200.00.

Buy Now Pay Later

Buy Now Pay Later is available on the majority of products we sell. No interest is payable as long as the full balance of the agreement has been cleared before the end of the 12 month period. You can elect to pay a deposit or not and you can control the payments on this agreement. You can settle the agreement early without any penalty and one payment can be left until the just before the end of agreement. You can also make regular payments by contacting Hitachi Capital.

Please note that monthly payments will commence 12 months from the date your agreement starts and will be payable of the same day of each subsequent month at an APR of 29.8% with interest calculated over 48 months on the original amount. If you settle any outstanding balance before the first repayment is due along with the administration fee of £29.00 then all interest charges are waived.

Although you will be contacted by Hitachi Capital as it reaches the end of the interest free period we highly recommend the client also diarises this separately due to the high APR if the balance is not fully cleared.

18 month Interest Free Finance

A new 18 month % free finance is also available on SELECTED products. Payments are balanced over the 18 month period with no interest on financed amount. You can elect to pay a deposit or not. No settlement fees are applied.

Interest Bearing Credit

Interest bearing finance is available over 24, 36 or 48 months at an APR of 19.9%. You can elect to pay a deposit or not. No settlement fees are applied. We can provide the monthly payment figures once the purchase(s) have been finalised.

All the applications can be completed by the customer and a link will be emailed to the application page. If preferred we can take the details over the phone and can normally confirm acceptance of your application status during the call. There are different consumer laws depending on whether the agreement is for an in-store purchase or distance selling.

Release of goods

Due to the statutory cooling off period for consumers please note that goods cannot be released for 14 days after the date the agreement was signed by the customer if details are taken over the phone. For those completing forms at our store goods purchased can be released immediately. We recommend contacting us before arranging a visit to Kent Home Cinema to ensure we have stock of the item as some of these are specifically ordered in for clients. The agreement can be pre-authorised before travelling to us to prevent a wasted trip. Please note that installation fees cannot be added to finance agreements – only the hardware.

All agreements are subject to status and in the event they are declined we are not given any reasons by the lender. We can provide contact details should the customer wish to appeal their decision.

Please call 01892 552563 for further details.
