Simaudio MOON W5.3 SE Differential Amplifier

The MOON W5.3 SE Differential power amplifier produces 150 watts per channel into 8Ω, 300 watts into 4Ω 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 SE 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

The SE version produces 175 watts into 8Ω, 350 watts in to 4Ω
and 700 watts in bridged mono configuration.

The SE version uses MOON Bipolar output transistors with unprecedented gain linearity
resulting in improved bass response and even more accurate sonic reproduction

Also unique to the SE version are 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.

Overseas MOON W5.3 SE 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.
