What customers say
Enthusiasts widely regard the Marantz MM8077 as a cornerstone for high-fidelity systems. The core theme is its exceptional power delivery, providing clean, effortless performance across all seven channels, even with difficult speakers. Reviewers consistently praise the sound signature as warm, musical, and highly detailed, offering significant improvements in clarity and soundstage depth over lesser amplification. Build quality is cited as robust, reflecting the premium brand's expected reliability.

Know before you buy
Yes, the MM8077 features both balanced (XLR) and unbalanced (RCA) inputs for every channel, allowing you to choose the connection type that best suits your pre-amplifier or processor.
The amplifier utilizes a combination of passive heat sinks and active fan assist. The fans are designed to be quiet and only engage when the system detects high thermal demand, ensuring they remain unobtrusive during normal listening levels.
With 150 watts per channel into 8 ohms and a high-current toroidal power supply, this amplifier is designed to handle demanding speaker loads with ease. It provides plenty of headroom for dynamic peaks in both music and home theater soundtracks.
Marantz's current feedback technology is designed to provide high-speed, wide-bandwidth amplification. This results in a more accurate, detailed soundstage and better transient response compared to traditional voltage feedback designs.
Because this unit generates significant power and heat, it is recommended to place it in a well-ventilated area. Ensure there is at least several inches of clearance on the top and sides to allow the heat sinks and cooling system to function efficiently.
You do not need to use all seven channels. You can use the MM8077 to power a 5.1 system, and the remaining two channels will simply remain idle without affecting the performance of the other channels.
