Simaudio MOON Evolution 860A Stereo Power Amplifier

MOON by Simaudio

The Evolution of amplification... Large power reserves allow the music to reproduce naturally and effortlessly.

  • The MOON 860A Power Amplifier is a balanced differential dual-mono design with both exceptional transparency and remarkable soundstage, despite its substantial output power rating. Ultimately, the 860A will mate seamlessly with virtually any loudspeaker, allowing it to reach its full sonic potential, regardless of its load.

    Several in-house developed advancements allow the MOON 860A to perform with both exceptional accuracy and a 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; (ii) our advanced “zero global feedback” circuit, commonly referred to as Lynx; and (iii) an over-sized power supply featuring 2 very large custom proprietary toroidal transformers for an improved power transfer and lower regulation factor, resulting in increased current speed and superior dynamics.

    Pairing the MOON 860A with the 740P Preamplifier, creates a compelling, high performance and “world-class” package. Of course, the key features you would expect from a MOON Evolution series power amplifier are present such as an RS-232 port and 12 Volt triggers for custom-install environments.

    • Our “Lynx” Technology which eliminates feedback and results in: Real-time amplification; More accurate musical reproduction with respect to tonality; Non-existent transient intermodulation distortion; The elimination of phase errors resulting from feedback.
    • Output stable to any known speaker impedance.
    • “Class A” power output to 5 watts for greater efficiency.
    • A high damping factor for superior musical dynamics,
    • improved signal speed and refined timbre accuracy.
