Feature-rich and finely built, the MOON 681 pairs seamlessly with the 641 and serves as a complete digital partner to any analogue amplifier.

The 681 accepts six digital sources, to which an HDMI input with ARC adds television sound. The analogue output level is set to 2, 3.5 or 6.5 volts RMS according to the amplifier connected. Construction is fully balanced.
The conversion section rests on the MDE-1 technology developed by the brand. Total harmonic distortion plus noise stands at 0.0003 % and intermodulation distortion at 0.0002 %. Dynamic range and signal-to-noise ratio both reach 125 dB.
The MiND 2 module handles network playback and access to online music services. Control runs from the MOON MiND Controller app. The MHV volume control allows a power amplifier to be driven directly.
Consumption falls to 15 watts at idle and 5 watts in low-power standby. Crosstalk measures -125 dB for a bandwidth of 2 Hz to 100 kHz. The unit is driven with the BRM-1 smart remote control.
