Simaudio MOON W5.3 SE BLACK Power Amplifier: Save $3,000!
175 watts per channel into 8 ohms, 350 watts into 4 ohms
700 watts in bridged mono configuration
Balanced circuitry up to the output stage
"At the top of my list of audio priorities is the elusive one of the emotional integrity of the performances… The paramount question I want a positive answer to is: 'Does this equipment convey the emotional integrity of the music, and does it aid or hinder my response to the music and the performer(s)?' By that standard, the Moons scored high."
-- Dan Davis, Soundstage Ultra Audio, on the MOON P5.3 Preamp and W5.3 Power Amp
The Simaudio MOON W5.3 SE Differential power amplifier produces 175 watts per channel into 8 Ohms, 350 watts into 4 Ohms and 700 watts in bridged mono configuration. Employing MOON’s world-renowned "Advanced Rennaisance" amplification circuit, the W5.3 SE produces a warm, grain-free sound common to some of the very best tube amplifiers, but has the reliability of solid state designs. You’ll also enjoy the tight, authoritative bottom end for which MOON power amplifiers are world-renowned.
This SE version uses MOON Bipolar output transistors with unprecedented gain linearity, resulting in improved bass response and even more accurate sonic reproduction. The SE version also offers tighter matching and tolerances for certain critical electronic parts.
Significant design features
A 12 Volt trigger for remote operations
A "no overall feedback" design resulting in genuine 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
Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor; the result is increased current-speed and better dynamics
Balanced circuitry up to the output stage
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 yielding superior musical dynamics, improved signal speed and refined timbre accuracy
A very short capacitor-free signal path for a faster transient response
Accurate matching of the very finest high quality electronic components
PCB w/ pure copper tracings & gold plating that yields low impedance characteristics
Stable to any known speaker impedance
Extremely rigid chassis construction to minimize the effects of external vibrations
A symmetrical circuit design
Designed to be powered up at all times for optimal performance
Low operating temperature to ensure a longer than normal life expectancy
Simaudio aims for nothing less than musical truth
Nestled in an industrial park just outside Montreal, Quebec, Simaudio has been manufacturing high-end, high-value music and home theater products since the company’s inception in 1980.
Beginning in 1997, the MOON Series has been the core and pride of Simaudio. MOON products have garnered numerous awards from around the globe and are recognized for outstanding build quality, sound performance, reliability and technological advancement. Every MOON component epitomizes sound quality that reflects a musical truth: to recreate the live musical event and draw the listener into the music.
MOON products are manufactured entirely in-house using state-of-the-art equipment. Electronic components are military-grade, and soldering techniques are of aerospace caliber. Simaudio also embraces “green processes” at all levels of manufacturing, from a stringent recycling philosophy to the elimination of hazardous materials used in the different manufacturing processes.
MOON components come with a 10-year warranty, and to further preserve your investment, a comprehensive 2-year “Factory Trade-Up Program” allows upgrades over time with little or no loss on the original purchase.
