AURALiC VEGA G2.2

A streaming DAC with Direct Data Recording technology, and analog preamp with ladder resistor volume.

AURALiC’s VEGA G2.2 streaming DAC is built upon the company’s impressive DAC lineage and houses Auralic’s Fusion DAC design, Direct Data Recording (DDR), and Galvanic Isolation technologies. It also features a fully analog preamplifier section with a proper analog ladder resistor volume control, delivering an exceptional noise-free signal to class-A ORFEO output modules.

The groundbreaking Fusion DAC operates independently of the source clock signal, and DDR technology records audio data into the streamer’s memory, and then re-clocks using 60-femtosecond technology for jitter-free performance. Combining Auralic’s proprietary digital filtering and oversampling technology with a precise switching network for the final digital-to-analog conversion stage, the VEGA G2.2 delivers superior sound quality. These cutting-edge technologies culminate into a transformative DAC, setting a new standard in digital audio performance.

Direct Data Recording

DDR records audio data directly into Tesla G3’s system memory in binary format, and then processes and outputs it to the DAC with dual 60 fs femtoclock. With one for 44.1x and another for 48x sampling frequencies, the clocks serve as a master that’s independent of the input signal. Thanks to these cutting-edge technologies, VEGA G2.2 is immune to input signal distortion and jitter, delivering unmatched sound quality. Experience an unparalleled listening journey with stunning detail, clarity, and precision.

The Fusion DAC

Auralic’s groundbreaking Fusion DAC design in the VEGA G2.2 combines the finest elements of discrete ladder and Delta-Sigma DAC designs, creating a new standard in audio excellence. This innovative approach involves modifying a high-performance, manufacturer DAC chip by bypassing most of its functions, such as PLL, digital filter, and oversampling circuits. In their place, Auralic deploys its proprietary clock reconstruction, digital filter, and oversampling technologies, ensuring that only the precise switching network inside the DAC chip is used for the final digital-to-analog conversion stage. The result is an extraordinary sound quality that elevates the listening experience to new heights.

An Analog Preamp

The VEGA G2.2 retains the successful analog preamplifier function from the original VEGA G2.1, now enhanced with an increased output level from 4.4 V to 6 V to cater to power-hungry amplifiers. The ORFEO class-A output modules ensure the balanced output can drive loads well below 600 ohm. Users have the option to disable the preamplifier function through software and reduce the output level to 2V, allowing for seamless integration with external preamplifiers. Additionally, a convenient home theater bypass mode is available for analog input channels, providing maximum flexibility for your audio setup.

Analog Volume Control

The VEGA G2.2 uses a resistor ladder volume control, which is recognized as the superior method for achieving high-performance audio playback. Unlike digital volume control, which accurately reduces the signal level but cannot address the noise floor, an analog volume control reduces both the signal level and noise floor while preserving the system’s dynamic range. By employing eight coil-latch relays, this volume control system consumes no power and emits no EMI noise when inactive, ensuring noise-free and distortion-free control. Once adjusted, the system remains electronically transparent, further enhancing the exceptional audio performance of the VEGA G2.2.

Galvanic Isolation

In the pursuit of an exceptional dynamic range that unveils intricate details in original recordings, modern high-end DACs demand utmost cleanliness in clocks, power supplies, and signal feeding. The VEGA G2.2 meet this challenge by incorporating high-speed galvanic isolators, strategically positioned between the Tesla G3 processing platform and the ultra-sensitive audio circuit. These isolators ensure complete physical separation and protection against interference, safeguarding the DAC from any noise coupling while enabling seamless data transfer. 

Unity Chassis II

The VEGA G2.2 chassis is a double enclosure, with a high-grade aluminum outer, and an inner case made from nickel-coated copper. A high-mass base and enhanced four-foot multi-spring suspension system complete the quiet, noise-defeating performance of the VEGA G2.2’s Unity Chassis II.

VEGA G2.2 internal circuits are physically distributed to enhance overall balance. And with specially designed foot spikes that dampen and absorb vibrations, the VEGA G2.2 is always rock-steady, for ultra-smooth signal delivery.
