Auralic Vega G 2.2 Streaming DAC, black

Description

he VEGA G2.2, built upon our impressive DAC lineage, houses our 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 our Class A ORFEO output modules. Its groundbreaking Fusion DAC operates independently of the source clock signal. Our DDR technology records audio data into the Tesla G3 platform's memory, which is re-clocked using our 60-femtosecond technology for jitter-free performance. Combining our 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.

Introducing VEGA G2.2 with AURALiC's proprietary Direct Data Recording (DDR) technology. 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 60fs Femto Clock - one for 44.1x and another for 48x sampling frequencies, serving as a master clock 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, free from any distortion or jitter.
 
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.

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.

Tesla G3 - A New Era for Wireless Streaming

Built on a quad-core 64-bit architecture, our Tesla G3 streaming platform delivers eight times the processing capability of its predecessor. Equipped with 4GB of DDR4 system memory, the Tesla G3 can easily handle even the most demanding processing tasks, making it a future-proof solution which will accommodate the rapidly evolving digital audio landscape.

The Tesla G3 platform also employs Direct Memory Access (DMA) technology for its audio input and output channels, enabling all audio-related hardware and software to access the system memory directly. This significantly reduces latency and jitter by 90% compared to Tesla G2, giving us more flexibility to fine-tune the performance and sound quality of our products.
