Power Amplifier

W-8Power Amplifier

The MOON W-8 is the Power Amplifier that has given the Evolution Series the recognition it should get. The Lynx circuit and the optimized integration of electronics and mechanic design made of this amplifier a wonder in itself. Acclaimed worldwide for its effortless power and musicality, the W-8 is still today considered a reference.

Launched in 2005, Discontinued in 2012

The MOON W-8 is producing 250 watts per channel of uncolored high-current output power at 8 ohms (500 wpc into 4 ohms and 1000wpc into 2 ohms), the W-8 will drive virtually any loudspeaker to its maximum capabilities with incredible ease. The MOON W-8 can be fully integrated into a custom-install environment via an RS-232 port and 12V trigger.

Technical aspects

Lynx circuitry which is a "no overall feedback" design resulting in genuine real-time amplification, a more accurate musical reproduction with respect to tonality, virtually non-existent IMD and the elimination of common phase errors resulting from feedback
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
A dual-mono oversized power supply
Precision matched and fully decoupled proprietary MOON Bipolar output transistors with unprecedented gain linearity resulting in improved bass response and even more accurate sonic reproduction
A high damping factor for superior musical dynamics, improved signal speed and refined timbre accuracy
A very short capacitor-free signal path for a faster transient response
Stable to any known speaker impedance
"Class A" output to 5 watts for greater efficiency
RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
12 Volt trigger input/output for remote operation
4-Layer printed circuit boards with pure copper tracings for a much shorter signal path; This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
Designed to be powered up at all times for optimal performance
Low operating temperature for a longer than normal life expectancy
Ultra rigid chassis construction to minimize the effects of external vibrations
Accurate matching of the very finest quality electronic components in a symmetrical circuit design.
