The MOON 861 is a power amplifier designed with a focus on delivering high fidelity sound and impeccable performance. It features the advanced MOON Distortion-Cancelling Amplifier (MDCA) technology, which removes global feedback to achieve audio purity. This amplifier is part of the North Collection and pays homage to the legacy of the MOON 888, encapsulating a sophisticated design philosophy that aims to provide the deepest soundstage and richest tonal characteristics. The high-efficiency power supply incorporates dual 1,500 VA low-noise MOON transformers and 228,000 µF capacitance to ensure stable thermal equilibrium, even under heavy load. It offers flexible operation modes, including a mono mode that allows the amplifier to output 800 watts into an 8-ohm load, and 300 watts per channel in stereo mode at 8 ohms, doubling to 600 watts at 4 ohms. The 861 also features a dual mono configuration and is equipped with a MOONLink technology for connectivity with other MOON products for system control and firmware updates. The product dimensions are 18.95 x 8.26 x 24 inches and it weighs approximately 125 lbs. Additionally, it comes with a 10-year warranty, emphasizing the manufacturer’s commitment to quality.
