MOON CLASSIC SERIES
Updated: April 24, 2006
W5.3 Balanced Stereo Power Amplifier
|
|
Also available with black faceplate
|
|
|
The MOON W5.3 balanced stereo power amplifier produces 150 watts per channel into 8 ohms,
300 watts into 4 ohms and can be configured for mono operation. The heir apparent to the legendary
MOON W-5 has arrived and encompasses all of the circuitry improvements found in the Limited Edition
series. Employing our world-reknowned "Advanced Rennaisance"
amplification circuit, the W5.3 produces a warm, grain free sound common to some of the very
best tube amplifiers, but has the reliability of solid state designs. Of course, the tight authoritative bottom
end that MOON power amplifiers are world-reknown for is included here at no extra charge.

Significant Design Features
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 ·
Balanced circuitry up to the output stage ·
Stable to any known speaker impedance ·
"Class" A output to 5 watts for greater efficiency ·
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 very short signal path for a faster transient response ·
A symmetrical circuit design ·
A 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.

Overseas MOON W5.3 RS
The RS series of MOON audio components benefit from an even higher standard of manufacturing process
than the regular MOON versions. All significant differences are contained within the circuitry and construction
of each model.
RS versions are built using different materials and parts in certain areas. For example, printed
circuit boards are of a higher temperature grade than that of the military specification FR-4 material
we normally use; Their traces are gold-plated instead of a tin/lead composite. As well, all capacitors
use improved dielectric materials.
MOON RS models meet and/or exceed stricter manufacturing processes as required to pass many
international safety standards such as those imposed by the E-U, Japan and South Korea. Cosmetically, the
ONLY difference is the RS logo on the front panel.
