870A

The MOON 870A Power Amplifier is a balanced differential dual-mono design that effortlessly outputs 300 watts into 8 ohms and 600 watts into 4 ohms. Transparency and soundstage are exceptional, despite this amplifier's high power rating. Ultimately, the 870A will mate seamlessly with any loudspeaker allowing it to reach its full sonic potential, regardless of its load.

Ultimately, the 870A will mate seamlessly with any loudspeaker allowing it to reach its full sonic potential, regardless of its load.

Several in-house developed advancements allow the MOON 870A, the most powerful 2-channel Evolution Series amplifier to date, to perform with both accuracy and grain-free character. These include (i) MOON output transistors, specifically designed for use in our amplifiers, providing tighter and more visceral bass performance, as well as unprecedented linearity thoughout the entire frequency spectrum; and (ii) our advanced "zero global feedback" circuit, commonly referred to as Lynx. 

Of course, key features you'd expect 

  • RS-232 port
  • 12 Volt triggers for custom-install environments.
  • Lynx Circuitry results in zero overall feedback resulting in zero intermodulation distortion or any common phase errors, which in turn produces a temporarily correct signal
  • Custom proprietary toroidal transformer resulting in low noise and spectacular dynamics
  • Dual mono Power supply
