MOON Evolution Series 860A Dual-Mono Power Amplifier

  • 200 watts per channel (WPC) into 8 Ohms and 400 WPC into 4 Ohms
  • Full unsolicited RS-232 bidirectional feedback
  • Lynx circuitry: "no overall feedback"
  • Precision matched and fully decoupled proprietary MOON Bipolar output transistors
  • Proprietary toroidal transformer design with lower magnetic, electrical and thermal loss
  • "Class A" output to 5 watts for greater efficiency

With a balanced differential dual-mono design that outputs 200 watts per channel into 8 Ohms and 400 watts into 4 Ohms, the MOON 860A Power Amplifier offers transparency and soundstaging of unusual quality for an amp with such a high power rating. Try the 860A in yoyur system and you'll hear for yourself how it can bring out the best in any loudspeaker.

MOON's engineers have developed several advancements that enable allow the MOON 860A to perform with both accuracy and grain-free character. These include MOON output transistors, which provide tighter and more visceral bass performance as well as unprecedented linearity thoughout the entire frequency spectrum, and MOON's advanced Lynx "zero global feedback" circuit, which results in more accurate tonal reproduction and practically non-existent IMD (Inter-Modulation Distortion.

Custom installation is facilitated with the RS-232 and 12 Volt triggers, and a wide range of user-selectable cosmetic options are available.

The MOON Evolution Series represents the pinnacle of luxury, performance and ease-of-use. Using a cost-no-object design approach yielding several new proprietary technologies, these products faithfully bring to life the true emotion of music. MOON's relentless quest for perfection has resulted in audio components that effortlessly transcend time and space, allowing you to feel the mesmerizing experience of a live musical performance, over and over again.

Significant design features:

  • Full unsolicited RS-232 bidirectional feedback
  • Lynx circuitry which is a ""no overall feedback"" design resulting in genuine real-time amplification, a more accurate musical reproduction with respect to tonality, virtually non-existent IMD and the elimination of common phase errors resulting from feedback
  • Precision matched and fully decoupled proprietary MOON Bipolar output transistors with unprecedented gain linearity resulting in improved bass response and even more accurate sonic reproduction
  • Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor. The result is increased current speed and better dynamics
  • An oversized power supply
  • 12 Volt trigger input/output for remote operation
  • "Class A" output to 5 watts for greater efficiency
  • A high damping factor yielding superior musical dynamics, improved signal speed and refined timbre accuracy
  • A very short capacitor-free signal path for a faster transient response
  • Stable to any known speaker impedance
  • 4-Layer PCBメs with pure copper tracings for a much shorter signal path; This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
  • Ultra rigid chassis construction to minimize the effects of external vibrations
  • Accurate matching of the very finest quality electronic components in a symmetrical circuit design
  • Designed to be powered up at all times for optimal performance
  • Low operating temperature for a longer than normal life expectancy
