MOON CLASSIC SERIES
W5.3 Stereo Preamplifier


 

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.
