It is engineered to operate in combination with the \u003cstrong\u003eMOON 461 power amplifier\u003c\/strong\u003e, ensuring optimal system performance across the range.\u003c\/p\u003e\n\n\u003ch2\u003eStreaming \u0026amp; Connectivity\u003c\/h2\u003e\n\u003cp\u003eAt the core of the 491 is MOON’s proprietary \u003cstrong\u003eMiND 2 streaming technology\u003c\/strong\u003e. It operates as a UPnP renderer and a \u003cstrong\u003eRoon Ready\u003c\/strong\u003e endpoint, with full support for \u003cstrong\u003eAirPlay\u003c\/strong\u003e and \u003cstrong\u003eBluetooth\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eMOON MiND Controller app\u003c\/strong\u003e (iOS \u0026amp; Android) provides access to major streaming services including \u003cstrong\u003eQobuz\u003c\/strong\u003e, \u003cstrong\u003eTIDAL\u003c\/strong\u003e, \u003cstrong\u003eDeezer\u003c\/strong\u003e, and \u003cstrong\u003eSpotify\u003c\/strong\u003e. The 491 also supports \u003cstrong\u003eQobuz Connect\u003c\/strong\u003e, \u003cstrong\u003eTIDAL Connect\u003c\/strong\u003e, and \u003cstrong\u003eSpotify Connect\u003c\/strong\u003e for seamless third-party control.\u003c\/p\u003e\n\u003cp\u003ePlayback and system functions can be controlled via the app, front-panel buttons, or the included aluminium \u003cstrong\u003eCRM-4 remote control\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch2\u003eDAC \u0026amp; Phono Stage\u003c\/h2\u003e\n\u003cp\u003eThe DAC section employs \u003cstrong\u003etwo ESS 9039Q2M converters\u003c\/strong\u003e configured in dual-mono mode, combined with a precision clock and refined output stage. This design maximizes channel separation while reducing noise and distortion — delivering a wider dynamic range, natural presentation, and improved spatial accuracy and micro-detail retrieval. The DAC board is mounted on a modular daughter board to support future upgrades.\u003c\/p\u003e\n\u003cp\u003eThe integrated \u003cstrong\u003ephono stage\u003c\/strong\u003e supports both \u003cstrong\u003emoving magnet (MM)\u003c\/strong\u003e and \u003cstrong\u003emoving coil (MC)\u003c\/strong\u003e cartridges via menu-configurable settings. Selectable input impedance: 47kΩ, 1kΩ, 470Ω, 100Ω, or 10Ω. Selectable input capacitance is also configurable, allowing the phono stage to be precisely optimized for any cartridge.\u003c\/p\u003e\n\n\u003ch2\u003ePower Supply\u003c\/h2\u003e\n\u003cp\u003eThe 491 features \u003cstrong\u003eMOON Hybrid Power (MHP)\u003c\/strong\u003e, a proprietary technology that blends traditional linear and modern switch-mode designs for ultra-stable, low-noise DC power. It operates at switching frequencies far beyond the audio band, ensuring sensitive circuits — including the phono stage — remain completely uncontaminated. The result is a lower noise floor with greater dynamic headroom.\u003c\/p\u003e\n\n\u003ch2\u003eVisit Our Showroom\u003c\/h2\u003e\n\u003cp\u003eHear the MOON 491 in a private audition at our Covina showroom.
