Moon 680D Streaming DAC

A refined network streamer with a generous set of feature set

You’ll find no shortage of connectivity here. There’s an impressive array of digital inputs taking in USB, AES/EBU, optical, and coax in both RCA and BNC forms. There are nine inputs in total, though number eight is reserved for the built-in streaming module and input nine is for aptX Bluetooth 


So, how does Moon provide next-level performance?

Look inside the 680D and we like what we see with the care taken over the circuit layout and power supply arrangement. The 680D uses Moon’s MHP (Moon Hybrid Power) power supply module, as used in the company’s even pricier, reference products.

The MHP module mixes both traditional linear and switch mode technologies to deliver a stable, low-noise, and power-efficient energy feed to the signal circuitry. The digital and analog sections are powered by separate outputs from the supply to avoid unwanted interactions and optimize performance.

Each of the nine digital inputs routs into an FPGA (Field Programmable Gate Array) that re-clocks the signal. The Moon’s is compatible with all files up to 32-bit/384kHz PCM and DSD256 files and should, therefore, cover pretty much everyone’s music file collection.

At the heart of the 680D is the ESS Sabre’s ES9028PRO DAC chipset which packs no fewer than eight DAC chips, configured so that four combine to create the signal for each channel. The output of each chip is carefully calibrated so that none of them is set to work at the same level which reduces distortion that may be common at any specific output level. 

Great care has been taken with the digital clocking system, too. It is carefully positioned to minimize jitter effects and has a dedicated precision voltage regulator to ensure a stable power feed. Once the digital music stream is converted to analog, it passes through a fully balanced output stage that, as expected, is packed with high-grade components.

What you get is a smooth and refined performer. It’s a friendly and accommodating balance – one that isn’t easily provoked by bright or aggressive recordings.



HiFi Plus loved the Moon 680D saying:

"The presentation is at times kaleidoscopic and thrilling. Ultimately, I listened to the entire album enthralled by the 680D’s wonderful presentation"

The Ear liked the Moon 680D and called it "mesmerizing"

 "The 680D delivered excellent timing, transparency, and articulation from a variety of recordings and produced a sound that was fully immersive with new as well as more familiar albums. It provides a strong connection to the performance that pulls you in and discourages track hopping so that the musical message gets through"
