The Auralic VEGA G2.2 builds upon the already impressive foundation of their predecessor, the G2.1, retaining key features such as the AURALiC’s proprietary Fusion DAC structure, Direct Data Recording (DDR), Galvanic Isolation, passive analog volume control, and analog pre-amplifier. The unique architecture of VEGA G2.2 and G3 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.
- Fusion DAC
When it comes to audio digital-to-analog converters (DACs), there are two primary designs: discrete ladder DAC and Delta-Sigma DAC. The popular discrete ladder DAC design allows designers to use different components for various parts of the circuit, providing greater flexibility in tailoring the sound signature. However, the discrete ladder DACs can suffer from non-linearities caused by precision mismatches in the resistor values. Uneven temperature changes also play a significant role in introducing non-linearity to the system. This can lead to distortion and reduced overall performance.
Delta-Sigma DACs are known for their high accuracy and resolution, which is achieved through precise manufacturing processes. These DACs also offer a high dynamic range and low noise and distortion level, making them well-suited for high quality music playback applications. However, Delta-Sigma DACs are often integrated with complicated digital circuits like Phase Lock Loop (PLL), digital filter, and oversampling circuits, which can make them less customizable for designers. This can limit their suitability for high-end applications where customization and flexibility are important.
AURALiC's Fusion DAC design in the VEGA G2.2 product has pioneering technology that combines the best features of discrete ladder and Delta-Sigma DAC designs. This innovative approach uses a high performance, manufacturer DAC chip as a basis for modification. Most of the DAC chips’ functions, such as PLL, digital filter, and oversampling circuits are bypassed, and instead AURALiC's proprietary clock reconstruction, digital filter, and oversampling technologies are deployed. This unique approach ensures that only the precise switching network inside a DAC chip is used for the final digital-to-analog conversion stage, resulting in exceptional sound quality. This Fusion DAC design facilitates a unique level of customization and flexibility, providing users with the ability to fine-tune and optimize the DAC to their individual preferences. Overall, AURALiC’s proprietary implementation of this unique, in-house developed technology represents a significant advancement in DAC design, offering exceptional performance and unparalleled sound quality.
- Direct Data Recording
The VEGA G2.2is equipped with AURALiC's proprietary Direct Data Recording (DDR) technology. Unlike traditional DACs that rely on a Phase Lock Loop (PLL) circuit to reconstruct the incoming clock signal, our DDR technology avoids using a PLL circuit as it cannot fully remove the distortion and jitter present in the original clock signal. Instead, we record the audio data directly into the Tesla G3 processing platform's system memory in binary format, bypassing the original clock signal entirely.
Next, a series of advanced digital filters and oversampling algorithms process the audio data, optimizing it for the best possible performance. To power the DAC operation and time the Tesla G3's data output to the DAC chip, a dual 60fs Femto Clocks - one for 44.1x and another for 48x sampling frequencies - acts as a master clock, independent of the input audio signal.
As a result of these cutting-edge technologies, the VEGA G2.2 is immune to the input signal's distortion and jitter, delivering the highest level of sound quality possible. The result is an unparalleled listening experience, with stunning detail, clarity, and precision that is free from any distortion or jitter.
- Passive Analog Volume Control
Analog volume control is widely regarded as the superior approach for achieving high-performance audio playback. Whilst digital volume control can accurately reduce the signal level, it cannot reduce the noise floor level of the output signal. As a result, when using digital volume control to attenuate the signal by a large amount, the system's dynamic range is inevitably heavily compromised. Analog volume control, however, can reduce both the signal level and noise floor, whilst retaining the system's dynamic range.
The VEGA G2.2 feature a true analog ladder resistor volume control that delivers exceptional and noise-free control without introducing any distortion. This volume control system includes eight coil-latch relays that remain inactive when not in operation, consuming no power and emitting no EMI noise. Once the system is adjusted, it remains electronically invisible, thereby further enhancing the already outstanding audio performance of the VEGA G2.2.
- Analog Preamplifier
The VEGA G2.2 maintain the successful analog preamplifier function from the original VEGA G2.1. This feature has been enhanced in the new design, with the output level increased from 4.4Vrms to 6Vrms to meet the demands of even the most power-hungry amplifiers. Additionally, the ORFEO Class-A output modules ensure that the balanced output can drive loads well below 600ohm with minimal degradation in performance.
If desired, users can disable the preamplifier function through software, with the option to reduce the output level to 2Vrms, allowing for the use of external preamplifiers. In addition, a convenient home theater bypass mode is available for analog input channels.
- Galvanic Isolation
Modern high-end DACs are capable of providing exceptional dynamic range that can reveal minute details in the original recording. However, achieving such a dynamic range requires extremely clean clocks, power supplies, and signal feeding into the DAC. To ensure that no noise can be coupled into the DAC circuit, the VEGA G2.2 and G3 are equipped with high-speed galvanic isolators that are strategically positioned between the Tesla G3 processing platform and the ultra-sensitive audio circuit. These isolators provide physical separation and protection against interference for the DAC whilst enabling data transfer.

Testimonials
Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.
The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.
