Launched in 1999, Discontinued in 2006

The MOON W-3 balanced differential stereo power amplifier produced 120 watts per channel into 8 ohms, 240 watts into 4 ohms and could be configured for mono operation. Employing our "Advanced Renaissance" technology featuring a "no overall feedback" circuit and bipolar output devices, the W-3 produced a warm, grain free sound common to some of the very best tube amplifiers, but had the reliability of solid state designs. The MOON W-3 possessed the same sonic signature as the larger and more powerful W-5 but at a more affordable price.

User manual

Technical aspects

A "no overall feedback" design resulting in real-time amplification, a more accurate musical
reproduction with respect to tonality, virtually non-existent intermodulation distortion and
the elimination of common phase errors resulting from feedback
An oversized power supply
A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss,
yielding an improved power transfer and lower regulation factor, resulting in increased current
speed and better dynamics
Fully balanced circuitry up to the output stage
Stable to any known speaker impedance
"Class A" output to 5 watts for greater efficiency
Precision matched and fully decoupled Bipolar output devices which offer superb linearity
throughout the entire audio frequency spectrum
A high damping factor which yields superior musical dynamics, improved signal speed and
refined timbre accuracy
Extremely rigid chassis construction to minimize the effects of external vibrations
Accurate matching of the highest quality electronic components to tolerances as low as 0.01%
A very short signal path for a faster transient response
A symmetrical circuit design
Optional 12 Volt trigger for remote operations
Pure copper circuit board tracings with extremely low impedance characteristics
Designed to be powered up at all times for optimal performance
Low operating temperature for a longer than normal life expectancy.
