ARIES G2.2, the ARIES G3 features several other significant advances:
- Proteus X1 Co-Processor
Proteus X1 co-processor is built around a Xilinx XC7A200T FPGA chip with over 200,000 logic cells and
740 DSP slices. This chip shares the Tesla G3 system memory, enabling powerful data processing
capabilities. With advanced processing techniques, Proteus X1 elevates the listening experience. Sub
optimal and early digital recordings can benefit from Proteus X1’s impressive processing power. The
optimisation process removes harshness and potentially improves the experience of listening to an
inferior recording. Music gains substance, space, and extra dynamic range as a result.
- Multiple Digital Inputs
The ARIES G3 offers a comprehensive range of digital inputs, including USB Audio, Coaxial (2), Toslink (2),
AES/EBU, and HDMI eARC (to be added via a software update in the future). Incoming signals from these
inputs are recorded as binary data into the Tesla G3’s memory, which eliminates any potential for jitter.
The data can then be processed and corrected using Proteus X1, based on the user’s preferences, before
being outputted either as processed or bit-perfectly, with a defined latency, to the desired output
- Dual 60fs Femto Clock
ARIES G3 aims to be the best possible digital audio source, achieved by the implementation of a dual
60fs Femto clocks – one for 44.1x and another for 48x sampling rate frequencies. These audio-optimised
clocks have extremely low close-in phase noise and can greatly enhance sound quality, setting a new
standard for signal timing. For the ultimate performance, adding LEO GX.1 will deliver a true state-of-the-
art digital source experience.
VEGA G2.2 – Streaming DAC
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 customisable for designers. This can limit their
suitability for high-end applications where customisation and flexibility are important.
AURALiC’s Fusion DAC design in the VEGA G2.2 and G3 products is a 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 customisation and flexibility, providing users with the ability to fine-tune and optimise
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
Both the VEGA G2.2 and VEGA G3 are 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
Next, a series of advanced digital filters and oversampling algorithms process the audio data, optimising
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 and G3 are 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
The VEGA G2.2 and G3 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 and G3.
- Analog Preamplifier
The VEGA G2.2 and G3 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
theatre 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
VEGA G3 – Streaming DAC

product, but a testament to our unwavering dedication to providing the most captivating and immersive
musical experience ever imagined.
- Proteus X1 Co-Processor
The Proteus X1 in the VEGA G3 is an advanced technology built around a Xilinx XC7A200T FPGA chip,
featuring over 200,000 logic cells and 740 DSP slices. This chip shares the Tesla G3’s 4GB DDR4 system
memory, allowing for powerful data processing capabilities. Unlike in the ARIES G3, the Proteus in the
VEGA G3 exclusively processes the signal with advanced digital filter and oversampling, ensuring that all
input signals work at the DAC’s optimal sampling frequency.
The algorithm running inside Proteus X1 of VEGA G3 is specially optimised processing the music signal
from online sources, whether it is through the built-in streamer or the digital inputs. This optimisation
significantly improves the listening experience for music that may not be available in highest resolution
- Better DAC, Higher Performance

a final output switch network for analog conversion at an even higher level of precision. This
advancement results in a significant 30% reduction in distortion and noise and a 50% improvement in
dynamic range, making the VEGA G3 an exceptional choice for even the most discerning listeners seeking
unparalleled audio performance.
- Pure DAC Mode
Pure DAC mode in the VEGA G3 allows for an optimised signal path by disabling the streaming
capabilities of the device. This feature is especially beneficial for users who prefer to rely on other
methods for streaming their audio content. With Pure DAC mode, the VEGA G3 provides the cleanest
possible signal path, resulting in a high-quality audio playback experience.
