MOON 400M Power Amplifier

The 400M Power Amplifier delivers extreme power while maintaining the delicacy and articulation of the finest amplifiers. It can drive virtually any loudspeaker with ease, providing a punchy bottom-end slam that anchors the music with authority and weight, immersing you in a live concert-like experience. On the high-end, it offers finesse, detail, and refinement that may redefine your perception of recorded music versus reality.

Without Equal

When paired with the MOON 350P Preamplifier, the combination is unmatched in its class. There’s no more refined pairing at this price point—ideal for discerning audiophiles and those who enjoy high-volume listening without compromising on sound quality.

Key Features

As expected from a MOON product, it comes equipped with essential features like 12V triggers and an RS-232 port for custom installation environments.

Design Features

  • Fully balanced differential circuitry.
  • Precision-matched proprietary MOON Bipolar output transistors for enhanced bass and accurate sonic reproduction.
  • Oversized power supply with a custom proprietary toroidal transformer design.
  • High damping factor for superior musical dynamics, faster signal speed, and more accurate timbre.
  • “Class A” output up to 10 watts for improved efficiency.
  • Carefully selected, high-quality electronic components.

Included Accessories

  • AC power cable
  • Owner’s manual
  • Warranty and product registration information (USA and Canada only)
