Description

Moon i5.3 RS Integrated Amplifier (Used)
(***This is RS latest version)
Very good condition, no box, no original remote, Comes with Marantz remote control.

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 extremely 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 c ommon 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.
