AURALiC Vega XLR symetrical DAC ES9018s 32bit/384khz USB class A Output

The AURALiC team had only one idea in mind when designing the 32 bit VEGA DAC: Create the perfect DAC without the inherent defects of the current technology.

The result is up to expectations with a real attention to detail, the fruit of a long study on problems related to sampling and digital filters of the Delta Sigma 32 bit DAC.

Programmable Auralic Sanctuary and Active USB:

The AURALiC Santuary processor from AchWave in ARM9 architecture (1000MIPS) contains all the technology programmed in the Auralic Vega DAC.

This processor works in conjunction with the "Active USB" input, the low-level physical layer of which is completely revised by AURALiC engineers, providing a high-level proprietary solution and effective galvanic isolation.

FEMTO type clock:

The internal clock of the DAC VEGA, core of the AURALiC technology has among the lowest rates of Jitter on the market with a clock of 82 Femtoseconds. The phase noise is thus insignificant even in the highest resolutions with -168dB / hz.

This clock stabilized in shielded temperature, in a case of metal making it insensitive to all external disturbances and mechanically inert.

Several digital filtering modes for natural rendering:

6 Filtering modes make it easy to adapt the sound signature in the mediumacute. Positions 1 to 4 are designed for PCM signals with the usual conventional Apodizing and Slow Roll filters.

Mode 4 is recognized as being the most efficient with a group delay of 2.15 Femtoseconds at a frequency of 44.1Khz.

Modes 5 and 6 are entirely dedicated to digital filtering of the DSD format, resulting in a background noise of -140dB.

The result is a natural sound without the artificial side of the competing solutions thanks to an "Exact Mode" of over-sampling without pre and post echo harmful for the music.

the DAC AURALiC VEGA succeeded in bringing a solution of over-sampling 32 bit to 1.5Mhz able to compete with the biggest references High-End of the market.

An Orfeo analog power supply and stages designed accordingly.

AURALiC was not content with 99% of competing brands to repeat the existing analog solutions on the market.

To perfect the Exact Mode technology, Orfeo AURALiC fully Class A modules with very low noise comply with the work performed by the Femtoclock Exact Mode clock and the ESS ES9018s DAC.

These pure class A modules are inspired by the best professional solutions (Neve 8078 mixer).

The two partners merge audio qualities that are usually diametrically opposed: a precise, dynamic soundof a great resolution and yet of a subjugating naturalness./ P>
