The MOON 650D Digital-to-Analog Converter / CD Transport follows in the footsteps of the highly acclaimed MOON 750D. Applying what is commonly referred to as trickle-down technology, we have created a product that yields almost all of the 750D's performance, but at a more accessible price-point. True 32-bit fully asynchronous digital audio playback is achieved by the 650D using a fully balanced differential dual-mono design featuring our own M-AJiC32 circuitry (an asynchronous jitter elimination system). Built around the ESS SABRE32 Ultra DAC operating in 32-bit Hyperstream™, the conversion process uses an astonishing 8 DAC's per channel. The final result is a product that will breakdown all the barriers, bringing you closer to the music than ever before, regardless of how your digital media is stored, be it on a CD, computer, music server, etc.
The back panel features a complete array of digital input (4) and output (2) connections to meet all the needs of today's ever-widening technologies, allowing
for a connection to virtually any digital source. The front panel includes a disc drawer for our own proprietary drive mechanism which represents a fifth input.
As well, an optional outboard power supply will be made available to further enhance the already astonishing performance of the MOON 650D.
Of course, all of the signature features you would expect in a MOON Evolution series digital product are present: our revolutionary M-Quattro
floating suspension, SimLink™, i²DCf, just to name a few, as well as both RS-232 and IR ports for custom-install environments. Finally, a plethora
of user selectable cosmetic options are available at the time of purchase.
Since November 2011 the asynchronous USB input is capable of 24-bit/192kHz performance.
An upgrade is available for units manufactured prior to this date.
