Fusion DAC - A Groundbreaking in DAC design

AURALiC's groundbreaking Fusion DAC design in the VEGA S1 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.

AURALiC's proprietary Direct Data Recording (DDR) technology 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 S1 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.

PureDAC Mode - Seek for the Ultimate Sound

PureDAC mode empowers the VEGA S1 to disable all streaming and network-related functions, dedicating all resources to digital signal processing and conversion tasks. In this mode, the VEGA S1 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 S1 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 S1 deliver unparalleled audio clarity and precision, revealing the true essence of your music.

Tesla G3 - A New Era for 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 2GB 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.

CD Playback and Ripping

Still have some love for your old CDs? Not to worry; you can plug a generic USB CD drive into your VEGA S1 then choose to play a CD, rip a CD while playing, or just rip.

As with AURALiC’s Lightning file streaming, our unique CD playback feature uses the same advanced, jitter-reducing Memory Playback technology. CD data is first read, and compared several times for accuracy into the system cache before playing. The result is elimination of potentially induced jitter from the transport, canceling any negative effects from the quality of your chosen CD drive, potentially improving performance beyond what’s offered from competitors’ CD players.
