MOON CLASSIC SERIES                                 Updated: December 5, 2006
W-5 Dual-mono Differential Power Amplifier


  MOON W-5 Dual-Mono Amplifier

Also available with black faceplate      

 



This balanced differential dual-mono power amplifier produces 190 watts per channel into 8 ohms, 380 watts into 4 ohms and can be configured for mono operation. Employing our "Advanced Renaissance" technology featuring a "no overall feedback" circuit and bipolar output devices, the W-5 produces a warm, grain free sound common to some of the very best tube amplifiers, but has the reliability of solid state designs.

 


  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 · 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 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 · An 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.
