Launched in 2012, replaced by the Néo 380D in 2013

Designed around our M-AJiC32 circuitry (an asynchronous jitter elimination system) performing in true 32-bit fully asynchronous mode, the MOON 380D featured the SABRE32 Ultra DAC operating in 32-bit Hyperstream™ where the conversion process used an astonishing 8 DAC's per channel. Raising the bar further, there were eight (8) digital inputs covering the full gamut of connections - AES/EBU, S/PDIF, Optical and USB. All of these inputs accepted a signal up to 24-bit/192kHz resolution. Finally, there was a full digital monitor loop (S/PDIF) to accommodate external devices such as a room correction component.

Enhancing this Digital-to-Analog Converter were two (2) separate options; (i) The MOON MiND music streamer module which is actually a 9th digital input via Wi-Fi or Ethernet connection, and (ii) a high quality remote-controlled volume circuit feeding both balanced (XLR) and single-ended ( RCA) analog outputs. The 380D was targeted at individuals with computer-based audio setups, large digital music collections or multiple digital sources.

Technical aspects

ESS Technology SABRE32 Ultra DAC / Digital Filter (ES9016) working in 32-bit Hyperstream™ to achieve unprecedented jitter immunity and low-level linearity via a patented Time Domain Jitter Eliminator
True 32-bit asynchronous Digital-to-Analog converter 
Digital Audio Signal Processing with M-AJiC32 (MOON Asynchronous Jitter Control in 32-bit mode)
Our own "Dual Jitter Control System" producing a virtually jitter-free digital signal below 1 picosecond for ultra-low distortion, and ensuring compatibility with virtually any connected digital device
Eight (8) digital inputs (AES/EBU x 2, S/PDIF x 3, TosLink x 2 and USB x 1) allowing for a connection to virtually any digital source, along with one (1) S/PDIF digital output
Optional MiND (MOON intelligent Network Device) module (the 9th input) via Wi-Fi or Ethernet input for multi-room streaming
Optional variable analog outputs (balanced & single-ended) using M-eVOL volume circuit, originally
developed for the MOON Evolution series. Accessible using the remote control, this volume operates
in 1.0dB increments. M-eVOL is based on a resistive array configuration with no sonic degradation of the audio signal at all volume settings
Full digital monitor loop on S/PDIF to accommodate external devices such as a room
correction component or digital recorder
Highly advanced separate digital and analog power supplies, each using a toroidal transformer
and 11 stages of voltage regulation
USB input with galvanic isolation which eliminates all ground current (i.e. no electrical connection)
between the USB device (computer, music server, etc.) and the 380D, preserving the accuracy of
the audio signal
The entire analog stage is a fully balanced differential circuit for increased dynamic range and
headroom, higher resolution, as well as improved signal-to-noise ratio
Advanced analog signal path using a DC servo circuit and proprietary 18dB/octave analog filter
12 Volt trigger output for remote operations
RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates
IR input for external control
SimLink™ controller port for 2-way communications with other compatible MOON components
 4-Layer printed circuit boards with pure copper tracings for a much shorter signal path; This results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
 Rigid chassis construction to minimize the effects of external vibrations
 Accurate matching of finest high quality electronic components in a symmetrical circuit design
Includes CRM-2 remote control.
