Call To Order

Power when and where you need it.

The MM7025 is expertly crafted to meet all your high powered needs and drive even the most demanding speakers by designing the entire unit to deliver consistent and precise power wherever and however you need it.

Use it in an AV setup to give your front channels an earth-moving boost or simply to make a sensational upgrade to an existing stereo system. And, because the technology is the same as that in the MM7055 and MM8003, using them in combination is fast, efficient and friendly. It's a great flexible customisation enabler. And, as with the big brother MM7055, it also includes a new stylish display, XLR inputs, DC triggers and Marantz power bus.

Marantz MM7025 - 2-Channel Power Amplifier

The MM7025 is the ideal two-channel main amplifier that delivers a whopping 140W RMS per channel at 8 ohms. Use it as an AV pre-amplifier to give your front channels an earth-moving boost or simply to make a sensational upgrade to an existing stereo system. And, because the technology is the same as that in the MM7055 and MM8003 using them in combination is fast, efficient and friendly. It’s a great flexible customisation enabler. And, as with the big brother 7055, XLR inputs, DC triggers and Marantz bus.

First Impressions

If you’re impressed by elegantly restrained industrial design, the MM7025 is guaranteed to make a lasting – and very positive – impression.


Power For Your System

The MM7025 current feedback power amplifier delivers 2x 140W (8 ohms RMS, 20Hz – 20kHz) to offer a refined audio experience.


Getting Connected

Both single-ended RCA and balanced XLR inputs assure system compatibility regardless of your preamplifier or processor.


Your System, Your Way

The MM7025 encourages various system configurations. Use one for dedicated two-channel listening, or use two to as zone amplifiers to power speakers in different rooms.



The Most Musical Sound

Extensively tuned by Marantz sound masters to deliver an exquisite sonic signature. No component leaves the hands of Marantz sound masters until it passes rigorous testing. Envelop yourself with the most musical sound, from any source.

The Power Supply

As befits a Marantz amplifier, the high-capacity power supply begins with an oversized EI-core transformer feeding carefully chosen capacitors capable of storing 30,000 µF of energy. This combination instantaneously delivers peak power to all amplifier stages for distortion-free reproduction of the most complex sources.

Marantz Sound Quality

The MM7025’s advanced technology serves all your listening needs. Current feedback circuits, also used in Marantz’s Reference Series amps, insure the purest sonic reproduction regardless of source. Another MM7025 virtue, and one directly traceable to its substantial current capability, is the control it establishes over difficult speakers to reproduce both dynamic musical peaks and whispered dialogue without blemish.

Output Devices

In the final amplification stage, specially selected LAPT Hyper-Power output transistors, originally selected for Reference Series use, deliver fortissimo and pianissimo passages with equal aplomb. To make sure they’re always operating at ideal temperatures, these transistors are mounted on a forced-air “thermal tunnel.”

High-Grade Connections

The MM7025’s heavy-duty, gold-plated, four-way binding posts accept virtually any choice of loudspeaker cable The amplifier is less than 14” deep from the front panel to rear speaker terminals. This lets you place the MM7025 almost anywhere – in a cabinet or on a shelf. Selectable single-ended and balanced inputs assure easy connectivity in any system. This is Marantz quality at its best.

A Versatile Power Amp

The Marantz MM7025 Stereo Power Amplifier answers many needs for both two-channel devotees and home theatre enthusiasts alike. It produces 140 watts of full-bandwidth, very low distortion power per channel, so it can precisely control demanding speakers in large rooms or deliver subtle nuance in smaller acoustic environments.

Remote Control

You’ll find rear panel connections for a “flasher” input that conveys On/Off commands from an infrared (IR) remote controller. There’s a DC trigger input (and output) that lets you ”daisy chain” one or several MM7025s to turn on and off in synchronization with your pre amplifier or surround processor. If you’re going to use the MM7025 with legacy Marantz products, there are RC-5 connectors to give you a level of operating convenience you might not have thought possible.

Backed by Over 65 Years of Heritage

The most musical sound. Founded in 1953, Marantz has a long and rich history of designing audio components embraced by music lovers and critical listeners around the world. Because Music Matters, the MM7025 carries on the long Marantz tradition of delivering a best-in-class listening experience for music and cinema.
