Audiophile essentials:
The hardware is crucial for the sound quality of an audio device, and Simaudio, as high-end enthusiasts, rely on certain technologies for the best possible sound experience.
Let’s take a closer look at the essential technical solutions and special features of Moon devices in general and the 891 in particular: The “Moon Digital Engine”, or MDE for short, is always responsible for perfect digital-to-analog conversion. In the 891 it is called MDE-3 and follows the principle of FPGA-based reclocking of the input signal.
The FPGA has been programmed by the Simaudio engineers and it’s only in the case of the 891 that it reclocks with femtosecond precision. The use of an FPGA instead of a crystal-based oscillator is unusual and quite complex. As a result, the input signals are practically wiped clean of jitter. What the two DACs working in dual-mono mode prepare is perfected by the FPGA.
By the way: The converters are ES9038Pro, which can also be found in comparatively inexpensive DACs. However, comparing the sophisticated build and circuitry of the converter section in any Moon DACs to those cheap and cheerful DACs is grossly inappropriate.

Simaudio also goes to great lengths when it comes to
volume control: the “M-Ray-2 Volume Control” in the 891 is based on a discrete R2R resistor network that makes extremely fine level adjustments in 640 steps. In contrast to an equally good solution with relays, there is absolutely nothing to be heard through loudspeakers or headphones. The complexity lies in the detail: it takes a lot of parts, and the resistance values must match perfectly. According to the technical specifications of the 891, the implementation appears to have been very successful.

Finally, the 891’s power supply unit is also designed to ensure unadulterated listening pleasure. It is called MHP, which stands for “Moon Hybrid Power”, has been developed entirely in-house and is characterized by its low noise level. The 891 is already set up for even better sounding music of the future: The rear connections labeled “EXT. SUPPLY” are ready for a soon to be available external power supply unit, which will probably go one better still in terms of linear and low-noise operation.
