AURALiC Vega G2.2 Streaming DAC

The unique architecture of AURALiC Vega G2.2 Streaming DAC avoids using a PLL circuit as it cannot fully remove the distortion and jitter present in the original clock signal.

Instead, it records the audio data directly into the Tesla G3 processing platform’s system memory in binary format, bypassing the original clock signal entirely.

As a result of these cutting-edge technologies, the VEGA G2.2 are immune to the input signal’s distortion and jitter, delivering the highest level of sound quality possible.

The VEGA G2.2 now incorporates the advanced Tesla G3 platform, providing a significant boost to it’s processing power and capabilities. Additionally, a new dual 60fs Femto Clocks powers the DAC operation and time the Tesla G3’s data output to the DAC. The result is an unparalleled listening experience, with stunning detail, clarity, and precision that is free from any distortion or jitter.

The VEGA G2.2 streaming DAC represents the latest evolution in high-end DAC performance and cutting-edge analog circuit. AURALiC is at the forefront of digital audio technology, continuously pushing the boundaries with innovative new technologies.

Features

Fusion DAC – A Groundbreaking in DAC design

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. Instead, AURALiC deploys its proprietary clock reconstruction, digital filter, and oversampling technologies, ensuring that only the precise switching network inside the DAC chip is utilized for the final digital-to-analog conversion stage.

The result is an extraordinary sound quality that elevates the listening experience to new heights.

The Fusion DAC design empowers users with unparalleled customization and flexibility, enabling fine-tuning and optimization to match individual preferences. AURALiC’s proprietary implementation of this unique, in-house developed technology represents a significant leap forward in DAC design, delivering exceptional performance and unparalleled sound quality.

Analog Preamplifier

The VEGA G2.2 retain the successful analog preamplifier function from the original VEGA G2.1, now enhanced with an increased output level from 4.4V to 6V to cater to power-hungry amplifiers.

The ORFEO Class-A output modules ensure the balanced output can drive loads well below 600ohm with minimal performance degradation. 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 incorporate a highly regarded true analog ladder resistor 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, 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.

PureDAC Mode – Seek for the Ultimate Sound

PureDAC mode empowers the VEGA G2.2 to disable all streaming and network-related functions, dedicating all resources to digital signal processing and conversion tasks.

In this mode, the VEGA G2.2 utilizes Direct Data Recording technology to store music signals from any digital or USB input in the past hour to Tesla G3’s system memory, allowing users to replay music from any point at any time.

Galvanic Isolation

In the pursuit of 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. With these advanced features, the VEGA G2.2 deliver unparalleled audio clarity and precision, revealing the true essence of your music.

Unity Chassis II

The VEGA G2.2 chassis has been designed as a double enclosure, where an outer case made from high-grade aluminum is supplemented with an inner layer made by 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.

Perfectly Balanced

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.
