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.
