About the i5.3

The Simaudio Moon i5.3 integrated amplifier is part of Simaudio's Moon Classic series, designed for exceptional sonic performance with a mostly dual-mono architecture where both channels share only the transformer and power cord. It delivers 85 watts per channel into 8 ohms and 130 watts per channel into 4 ohms, powered by a massive 500-volt-amp toroidal transformer that minimizes magnetic, electrical, and thermal losses to improve current delivery and dynamics. The amplifier section operates in class A/B with the first 5 watts in pure class A, while the preamplifier section is fully class A. It features a very short signal path of approximately 14-15 inches from input to output, no overall feedback, and uses high-quality components including J-FET input devices and precision matched bipolar output transistors. The i5.3 includes five RCA inputs (one bypassing volume control for home theater processors), two RCA outputs, and sturdy WBT binding posts for speaker connections. It comes with a full-function all-aluminum remote control and a generous ten-year warranty. Sonically, it is noted for sparkling highs, detailed and vibrant sound with a hint of warmth and forwardness in the midrange, providing a lively and engaging listening experience. The chassis is rigid and vibration-resistant, weighing 28 pounds and measuring 17"W x 4"H x 15"D. The unit is designed to be powered on continuously for optimal performance and longevity.
