Marantz MM7055 Five-Channel Power Amplifier

Formidable Marantz MM7055 Five-Channel Power Amplifier Delivers 140 Watts of High-Current Power from Each of Its Channels

"Offers Excellent Value for the Money": Marantz MM7005 Five-Channel Power Amplifier Features Massive Power Supply and Foolproof Connectivity

You can’t do better for your dollar than with the Marantz MM7055 five-channel power amplifier. This heavy-duty amp pumps 140 watts of high-current power from each of its five channels. A massive power supply, cooling “thermal tunnels,” and foolproof connectivity explain why Home Theater raves MM7055 “offers excellent value for the money.” Backed by our Money-Back Guarantee, MM7055 is sure to please.

"The MM7055’s sonic performance was plenty good on everything, and the Marantz never ran out of gas at the levels I was listening. The MM7055 offers excellent value for the money."
– Michael Fremer, Home Theater

Big, Beefy, and Musical: MM7055 Designed to Deliver High-Grade Current
Stuffed with amplifier boards derived from the Marantz Reference SM-11 amplifier, MM7055 sounds bigger, beefy, and musical. It has power to spare, too, with 140Wpc on tap and a massive EI core transformer delivering plenty of current to drive even notoriously difficult loudspeakers. A gorgeous faceplate, part of Marantz's new aesthetic, claims a composite of aluminum and non-resonant resin. This rounded design, adorned with the Reference Series' trademark "porthole" power light, gives MM7055 a gloriously retro look with modern appeal.

The Inside Matters, Too
Marantz bolted in a massive power supply with a multiple-secondary EI-core transformer and more than 65,000 µF of custom-designed energy storage capacity. This amplifier uses the LAPT Hyper Power output devices, first used in Reference Series components. Current feedback topology ensures astounding accuracy and control under high-demand conditions.
