Moon by Simaudio Evolution 750D DAC / CD
MOON 750D DAC/CD Transport - Front
The MOON 750D Digital-to-Analog Converter / CD Transport features the most advanced digital technology; The first true 32-bit fully asynchronous digital audio playback system to reach the marketplace. Intended to fulfill the demands of the most discerning music connoisseur, the 750D is a fully balanced design featuring our new M-AJiC32 circuitry (an asynchronous jitter elimination system) built around the ESS SABRE32 Reference Audio DAC. The conversion process uses 8 DACs per channel working in 32-bit Hyperstream. The final result is previously unattainable musical reproduction from digital media, be it a CD, computer, music server, etc. In addition, the MOON 750D is extremely flexible and exemplifies a luxurious lifestyle.
The back panel features a complete array of digital input (4) and output (2) connections to meet all the needs of todays ever-widening technologies. The front panel includes a disc drawer for our own proprietary drive mechanism which represents a fifth input. As well, in the coming months, an optional outboard power supply will be made available to further enhance the already astonishing performance of the 750D.
The most realistic and lifelike sound
Of course, all of the signature features
youd expect in a MOON 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.
The RS series of MOON audio components benefit from an even higher standard of manufacturing process than the regular MOON versions. All significant differences are contained within the circuitry and construction of each model.
RS versions are built using different materials and parts in certain areas. For example, printed circuit boards are of a higher temperature grade than that of the military specification FR-4 material we normally use; Their traces are gold-plated instead of a tin/lead composite. As well, all capacitors use improved dielectric materials.
MOON RS models meet and/or exceed stricter manufacturing processes as required to pass many international safety standards such as those imposed by the E-U, Japan and South Korea. Cosmetically, the ONLY difference is the RS logo on the front panel.
Significant Design Features:
The USB input on the MOON 750D accepts a digital audio signal of up to 16-bits/48kHz. This is the native specification of the USB input. However, if you require a higher sampling rate, there are ways to achieve this with the 750D.
Rather than including a USB input for sampling rates exceeeding 48kHz, we opted to provide the best possible power supply, D/A converter and analog stage in the MOON 750D at this price level. Also, keep in mind that USB wasnt originally intended for use with hi-resolution audio; there are latency issues which compromise sound quality (i.e. jitter and phase errors, etc.). These could be minimized through dedicated costly circuitry, but this would significantly drive up the cost of the 750D without improving the sonic performance on any of the other inputs.
If you intend to use the MOON 750Ds USB input, its very likely that your computer is a data source for music. Today most computers with a built-in sound card will have either an S/PDIF (RCA connector) or Toslink (optical connector) digital audio output, thus eliminating the need for a USB input on the 750D. Furthermore, if youre committed to getting the most out of the music stored on your computer, then in all likelihood you have installed an after-market soundcard in your computer. Virtually all of these soundcards have at least one S/PDIF, Optical or AES/EBU (XLR connector) digital output. At this point, USB connectivity becomes irrelevant. The USB input is there for convenience as opposed to performance.
In the event that you wish to use your computers USB connection with files greater than 48kHz, there are several relatively inexpensive after-market products; compact one-box USB-to-S/PDIF interfaces that will work with USB datastreams up to 24-bit, all the way up to 192kHz.
