Excellent in features, MOON 681 is based on advanced MOON digital audio technology to offer seamless playback alongside the MOON 641, as well as serving as a complete digital front-end for any analog amplifier. Accessing digital libraries and online streaming services has never been easier than with the pioneering MiND2 platform, which recreates digital audio in every detail and is integrated into this masterpiece of High Fidelity.

An attractive 4.3" OLED screen displays the album artwork and artist name, while the BRM-1 remote control and MOONLink communication make it a pleasure to use and integrate into a single-brand MOON system. MHV (MOON Hybrid Volume) technology uses a clever mix of digital attenuation and analog gain levels to achieve high-performance volume control when the 681 is not connected to a MOON preamplifier, keeping the audio signal unchanged in the digital sphere.

At the core of the MOON 681 is the MDE1, a re-clocked FPGA with innovative DAC that converts the audio signal with industry-leading precision. Equipped with the MiND2 streamer, the 681 accesses libraries from TIDAL, Qobuz, Deezer and HighResAudio; It is compatible with Bluetooth, AirPlay2, Spotify Connect and TIDAL Connect; It is Roon Ready, decodes all stereo audio formats - including MQA and DSD - and can be synced with other MiND2 devices to create a multi-room experience.

Designed to accompany the 641, the 681 transforms any digital audio source into a revealing sound wave perfect for being driven by any amplifier. The 681 and 641 are archetypes of the Streaming DAC and integrated amplifier, and prove the absolute mastery of Canadian MOON engineering.
