The Auralic VEGA G2 Streaming DAC is the next generation of the company's successful Vega DAC. Accepting music up through DSD512 and PCM 32/384 kHz, the G2 is a much different product than previous versions. This streaming DAC is literally a newly designed VEGA DAC and newly designed ARIES in a single chassis. The VEGA G2, like the ARIES G2, is built on Auralic's Tesla hardware platform and LIghtning streaming infrastructure.
Hifi+ magazine's award, 'Best Streamer / Network Player of 2018' for the Vega G2 Streaming DAC.
For the first time in the audio industry, it’s a DAC that operates independently of the source signal’s frequency: VEGA G2 buffers data in such a way that it has no need to lock on to the frequency of its source signal. Never before has a DAC been able to entirely govern timing with its own clocking. The VEGA G2 features dual 72 femto master clocks in this industry-first design approach. Unlike the ARIES G2, the VEGA G2's clocks each handle a sample rate family. One handles sample rates in multiples of 44.1 while the other multiples of 48 kHz. These are 72 femtosecond clocks, that's 72 quadrillionths of a second. They have -169dBc/Hz of phase noise and a 100 Hz offset noise level of only -118dBc/Hz.
The Tesla platform for the VEGA G2 includes an ARM Quad-Core A9 chip, 1GB DDR3 RAM and 4GB of storage. The new processor is capable of calculation speeds 25 times faster than the original VEGA series. Why does this matter? A faster processor enables Auralic to use much more sophisticated DSP, filtering algorithms and oversampling / upsamping techniques than in all previous VEGA DACs. Many people today are using external PCs to do upsampling and filtering because their DACs don't have the power or ability to run specialized DSP algorithms. The VEGA G2 should be a product that will enable consumers to seek a middle ground between super powerful external PCs capable of extremely complicated filtering and resampling and more traditional DACs with much less capabilities because of hardware limitations.
The VEGA G2's powerful hardware enables what Auralic calls flexible filter mode. This is the next generation filter mode with four user selectable filters. The names of the modes are recognizable to existing Auralic customers, "Precise Mode maximizes in-band ripple and out-band attenuation performance for example, while Smooth Mode eliminates pre-ringing. Dynamic and Balance Modes round out the available options that provide an extra level of control for your listening." Similar to the ARIES G2, the VEGA G2 also has similar galvanic isolation and dual low noise linear purer-power supplies."

' AURALiC has been impressing us for some time, but the current G2 series (first seen at Munich High End 2017) really blows us away, for its build, its functionality, its performance... in fact, practically everything! The VEGA G2 is in a category that didn’t exist a few short years ago: the streaming preamplifier with built-in DAC. Effectively a nerve centre for a good audio system – just add power amplifiers and you have a complete system that’s very good to go – the VEGA G2 is very much a product of today... and tomorrow '
