Launched in 2000, Discontinued in 2002

The MOON i-5080 integrated amplifier combined numerous technologies found in Simaudio MOON preamplifiers and power amplifiers. Offering very high quality sonic performance, it represented an affordable alternative to the MOON i-5. Features include remote control operation, 80 watts per channel into 8 ohms and a preamplifier output.

User manual

Technical aspects

An oversized power supply
A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss,
yielding a much better power transfer and lower regulation factor, resulting in improved current
speed and better dynamics
An extremely short capacitor-free signal path measuring under 20 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 to 5 watts to maintain efficiency
Precision matched Bipolar output devices which offer superb linearity throughout the entire audio
frequency spectrum
Accurate matching of the high quality electronic components
A symmetrical circuit design
Pure copper circuit board tracings with extremely low impedance characteristics
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.
