Simaudio’s new MOON 680D streaming DAC expands and redefines the expectations of digital music playback. With its high-end luxe-looks, exemplary build quality, superior connectivity and onboard MiND 2* streaming module, the 680D is a future-proofed streaming DAC designed to combine simplicity of use with an extraordinary musical performance.

The design team at Simaudio has taken the blueprint of the 680D’s big brother, the award-winning 780D v2, to carefully craft this multi-talented streaming DAC using the very latest in performance audio technology and the finest of materials.

The 680D is an extraordinarily accomplished digital-to-analogue convertor and, at the same time, it is a feature-packed network streamer. An abundance of digital inputs, plus DAC architecture that embraces the finest in digital audio delivery (PCM up to 32-bit/384kHz and DSD256), ensures the 680D will make digital music sound its absolute best, no matter the source.

As well as class-leading D-to-A conversion, the 680D also delivers an easy-to-use and comprehensive network streaming experience. Premium music services TIDAL Masters, Qobuz Sublime+ and Deezer Hi-Fi are integrated into the MiND 2 streaming module. Bluetooth aptX is on board as well as ethernet connectivity to ensure absolute signal stability. The 680D is Roon-ready and MQA certified too.

The 680D exhibits an astounding degree of detail retrieval and musicality and has been tuned and designed to be paired with the MOON 600i v2 integrated amplifier – a combination which truly takes the listening experience to the next level. The 680D can of course be partnered with any amplifier, but when used with other MOON components full system control is available through the bespoke app to guarantee an enhanced user experience.

From every conceivable digital source, at any file size or standard whatsoever, the MOON 680D is the comprehensive answer to the question of digital audio quality. 

John Carroll of Renaissance said, ‘The 680D streaming DAC is the response to the many requests we have had from both consumers and retailers who wanted to get close to the performance and flexibility of the 780D v2, but at a more affordable price point. The 780D v2 remains our reference performer, but with the 680D we now have a perfect partner for the 600i v2 amplifier!’
