MOON W-3 Stereo Power Amplifier

Congratulations!

Thank you for selecting the MOON W-3 Stereo power amplifier as a part of your hi-fi reproduction
system. This power amplifier has been designed to offer state-of-the-art high-end performance in an
elegant package, while retaining all the sonic hallmarks on which Simaudio has made its reputation.
We have spared no effort to ensure that it is one of among the finest two-channel amplifiers available.
We have been building high-performance audio equipment for over 20 years, and the know-how
gained through our cumulative experience is an important reason why MOON amplifiers are so
musically satisfying.

The performance of your W-3 will continue to improve during the first three weeks of use. This is the
result of a “break-in” period required for the numerous high quality electronic parts used throughout
this amplifier.

Please read this manual thoroughly to acquaint yourself with this product’s features prior to using it.
We hope you enjoy listening to the MOON W-3 Stereo power amplifier as much as the pride we have
taken in creating this fine audio product. We understand the power and emotion of music and build
our products with the goal of reproducing these elusive qualities.

MOON W-3 Stereo Power Amplifier

Introduction

Your MOON W-3 Stereo power amplifier incorporates many significant design features to achieve its
“world class” level of performance. This is an abbreviated list of the more important features:

Proprietary “Advanced Renaissance” Technology which eliminates feedback. The results are as follows:
Real-time amplification is achieved since interactions from the speaker back to the amplifier are virtually
eliminated; More accurate musical reproduction with respect to tonality; Virtually non-existent transient
intermodulation distortion (which is far more degrading to sonic performance than harmonic distortion);
The elimination of common phase errors resulting from feedback.

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 differential circuitry up to the output stage.

Output stable to any known speaker impedance.

Class A output to 5 watts for greater efficiency.

An oversized power supply.

An exceptionally short signal path for a faster transient response.

Precision matched 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 very finest high quality electronic components.

A symmetrical circuit design.

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.
