MOON 861 300W Dual-Mono Stereo Power Amplifier
Product Description
Built for those who demand precision and power, the MOON 861 stereo power amplifier stands out with its dual-mono design, delivering an impressive 300W per channel into 8 ohms and 600W into 4 ohms. This powerhouse is engineered with MDCA architecture, ensuring distortion stays below 0.001% even at full power, so your music remains clear and true.
The heart of the MOON 861's performance is its pair of 1500 VA custom low-noise toroidal transformers, coupled with 240,000 Β΅F of power supply capacitance. This combination provides dynamic peaks effortlessly, while side-mounted heatsinks manage thermal dissipation effectively. The analog circuits are physically separated, minimizing capacitive coupling and maintaining signal purity.
This amplifier integrates seamlessly with setups demanding headroom and stability, featuring both RCA and XLR inputs and a MOONLink port for coordinated operation with MOON preamplifiers. Whether it's a dedicated listening room or a living room that doubles as one, the MOON 861 promises a performance that disappears behind the music.
