Simaudio MOON i-3 SE Integrated Amplifier

The MOON i-3 SE integrated amplifier combines numerous technologies found in Simaudio MOON preamplifiers and amplifiers. Offering very high quality sonic performance, it represents an affordable alternative to the MOON i-5. Features include remote control operation, a maximum continuous power output rating of 100 watts per channel into 8 ohms (160 watts into 4 ohms), six line-level inputs including a "home theater ready" input and a preamplifier output.

The SE (Special Edition) version of the MOON i3.3 benefits from electronic parts with higher tolerances in several key areas of the circuit. The result is improved sonic performance.

The SE version of the MOON i3.3 is available ONLY in North America

Significant Design Features:

· 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
· An extremely short capacitor-free signal path measuring 18.5 inches in length from input RCA's to
output binding posts, eliminating virtually all potential sources of interference and producing a
sonically faster transient response
· Gain section using a Crystal microprocessor functioning as a "shunt to ground" that doesn't
degrade sonic performance regardless of the setting
· One single-ended audio input which bypasses the gain stage to accomodate a component, such
as a home-theatre processor, whose own volume control is used instead
· Amplifier section using a "no overall feedback" design resulting in real-time amplification, more
accurate musical reproduction with respect to tonality, virtually non-existent intermodulation
distortion and the elimination of common phase errors resulting from feedback
· "Class A" output power to five watts for greater efficiency
· Precision-matched Bipolar output devices which offer superb linearity throughout the entire
audio frequency spectrum
· A symmetrical circuit design
· Accurate matching of the high quality electronic components
· Pure copper circuit board tracings with extremely low impedance characteristics
· Improved reliability through the elimination of moving parts
· Designed to be powered up at all times for optimal performance
· Low operating temperature for a longer than normal life expectancy.

Overseas MOON i-3 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.
