Extremely powerful, yet with a delicacy and articulation of the best amplifiers out there, the 400M can take on virtually any loudspeaker you connect it to. Delivering a bottom-end slam, with authority and weight to the foundation of the music, it will transport you into a live concert environment. On the top end of the musical spectrum, the 400M delivers finesse, detail and refinement that can challenge your perception of reality vs. recorded music.

A "no overall feedback" design resulting in genuine real-time amplification, a more accurate musical reproduction with respect to tonality, virtually non-existent intermodulation distortion and the elimination of common phase errors resulting from feedback.

Precision matched proprietary MOON Bipolar output transistors with unprecedented gain linearity, resulting in improved bass response and even more accurate sonic reproduction. A high damping factor for superior musical dynamics, improved signal speed and refined timbre accuracy. Fully balanced differential circuitry.

Made In Canada.
