The MM7025 is this year’s ideal two-channel main amplifier with a whopping 140W rms into 8 ohms per channel. 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 bus.

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.
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.”
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 dialog without blemish.
Remote Control, Too
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 preamplifer 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.
