MOON 641 125W Integrated Amplifier with MDCA Technology
Product Description
Built around a dual-mono layout, the MOON 641 Integrated Amplifier stands out with its 125W per channel at 8 ohms and 250W at 4 ohms, ensuring robust performance across various speaker setups. The MDCA (MOON Distortion-Cancelling Amplifier) circuit operates outside the signal path to minimize distortion, all without relying on global feedback. This attention to detail means your music retains its clarity and dynamic range.
Complementing its power, the M-VOL3 system offers precise gain control, maintaining stability even at low listening levels. With a damping factor of 700 and a signal-to-noise ratio of 109 dB, the 641 ensures your sound remains tight and clean, whether you're using it in a dedicated listening room or a living room setup.
For those who appreciate a modern touch, the 4.3" color display simplifies everyday operation, while MOONLink connectivity integrates effortlessly with other North Collection components. The intelligent BRM-1 remote further enhances usability, allowing you to control the amplifier with ease.
