Powerful

Extremely powerful, yet with a delicacy and articulation of the best amplifiers out there, the 400M Power Amplifier 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.
