MOON CLASSIC SERIES                                 Updated: December 19, 2006
i5.3 Dual-mono Integrated Amplifier


 

Also available with black faceplate      

 



A legend is reborn … The MOON i5.3 Integrated Amplifier continues where the astounding MOON i-5 left off. More power and transparency are just the tip of the iceberg; Producing a maximum continuous power output of 85 watts per channel into 8 ohms and 130 watts into 4 ohms, the MOON i5.3 is housed in our highly regarded ultra-rigid chassis. Featuring five line-level inputs, a user-configurable “home-theater ready” input, an IR input for the flexibility of external control and military-specification internal components, this integrated amplifier offers a level of sonic performance found in some of the very finest separate amplifier/preamplifier combinations.

A home entertainment system built around the MOON i5.3 provides for a unique opportunity to own a significant piece of audio history. Magnificent performance, genuine ease-of-use and an elegant physical appearance all wrapped into one very dynamic package.

 

 
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 only 14 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 · Amplifier section using a "no overall feedback" design resulting in real-time amplification, more accurate musical reproduction with respect to tonality, virtually non-existent IMD (intermodulation distortion) and the elimination of common phase errors resulting from feedback · Gain section using a Crystal microprocessor functioning as a "shunt to ground" that doesn't degrade sonic performance regardless of the selected setting · "Class A" output power to five watts for greater efficiency · One single-ended audio input which bypasses the gain control stage to accomodate a component, such as home-theatre processor, whose own volume control is used instead · Precision matched Bipolar output devices which offer superb linearity throughout the entire audio frequency spectrum · Accurate matching of the very finest high quality electronic components · A symmetrical circuit design · Pure copper circuit board tracings with extremely low impedance characteristics · Extremely rigid chassis construction to minimize the effects of external vibrations · Improved reliabilty 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 i5.3 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.
