Rooted in the principles of choice, natural sound, and reliability, Sonically, Auralic's meticulously engineers both their software and hardware to deliver a neutral and natural sound profile, empowering you to tailor your musical preferences through speaker selection and room setup.

Analog Preamplifier

The VEGA S1 retains the successful analogue preamplifier function from the VEGA G2.2. 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.

Groundbreaking Fusion DAC

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.

PureDAC Mode

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.

Optional Upgrade:  S1 External Purer-Power Supply Unit 

For those seeking an even higher level of audio quality, AURALiC offers an optional upgrade: the S1 External Purer-Power Supply Unit. This unit bypasses the internal power supply of the  VEGA S1, doubling the power capacity for enhanced performance. Featuring two dedicated transformers and Purer-Power low noise power supply circuits, the upgraded unit ensures a total galvanic isolation between the Tesla G3 processing circuit and audio circuits. This separation eliminates interference and minimizes noise, resulting in superior sonic performance that elevates your listening experience to new heights.
