MOON W5.3 Stereo Power Amplifier

Congratulations!

Thank you for selecting the MOON W5.3 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 among the finest two- channel amplifiers available. We have been building high-performance audio equipment for over 25 years, and the know-how gained through our cumulative experience is an important reason why MOON amplifiers are so musically satisfying.

Your new amplifier is a true Stereo design, whereby each channel operates completely independent of the other. The chassis, power cord and power switch are the only parts of this amplifier that both channels share. The performance of your W5.3 will continue to improve during the first 300 hours of listening. This is the result of a “break-in” period required for the numerous high quality electronic parts used throughout this amplifier.

Before setting up your new MOON W5.3, we encourage you to please read this manual thoroughly to properly acquaint yourself with its features. We hope you enjoy listening to the MOON W5.3 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 faithfully capturing these elusive qualities.
