The MOON 491 brings together network playback, preamplification, digital-to-analog conversion, phono playback, and headphone listening in one premium component. Positioned at the heart of the Compass Collection, it is designed to handle digital and analog sources with precision, flexibility, and refinement.
At its core is MiND 2, MOON’s proprietary network streaming platform. The 491 uses the UPnP protocol, is Roon Ready, and supports Apple AirPlay, Bluetooth, Qobuz Connect, Spotify Connect, and TIDAL Connect. With the MOON MiND Controller app for iOS and Android, listeners can access major music services including Qobuz, TIDAL, Deezer, and Spotify.
The 491 also integrates MOON Hybrid Power, a proprietary power supply architecture designed to deliver ultra-stable, very low-noise DC power. Operating at switching frequencies beyond the audio band, it helps protect sensitive audio circuits and contributes to a lower noise floor.
Its DAC section uses two ESS 9039Q2M converters in dual-mono mode, paired with a precision clock and a refined output stage. This architecture supports stable, precise, and detailed digital-to-analog conversion.
As with all MOON products, the 491 is backed by a 10-year warranty.
