The MM8077 is Marantz's biggest multi-channel amplifier, with 150 watts of power in each of its seven channels. The MM8077 is designed to complement the new Marantz AV processors, such as the AV8801 that we recently reviewed. The design of the MM8077 follows that of the AV8801, with a porthole in the center of the brushed-black front panel and curved sides that make for a clean and attractive style.

• Consistent power:  The power supply features a high current toroidal power transformer along with high power (71WVDC) filter capacitors with a total 100,000µF capacitance to easily handle sharp short-term transient peaks.
• Ultimate surround sound experience:  Designed for the ultimate music and movie surround sound experience, the Marantz MM8077 7-channel power amplifier delivers power and detail, and is rated at 150 watts per channel into 8 ohms, and 180 watts per channel into 6 ohms.
• Unique current feedback:  Featuring our unique current feedback discrete power amp output stages that are identical for all channels, the MM8077 is equipped with multiple high current discrete power transistors that feature high slew rate and wide operating bandwidth to extract the most detail from today’s high-resolution audio formats.
• Heat sink assembly:  The output devices are mounted on our unique dual extruded aluminum alloy heat sink assembly, configured in a tunnel arrangement that provides both passive and active cooling. The massive heat sinks feature multiple ribbed fins that provide a large passive cooling area,
