Auralic Vega S1 - Streaming DAC

The Auralic Vega S1 inherits AURALiC's innovative technologies from the VEGA G2.2. At its core lies AULALiC's proprietary Fusion DAC, a groundbreaking innovation that seamlessly integrates the finest elements of discrete ladder and Delta-Sigma DAC designs.

In addition to this advanced DAC technology, the VEGA S1 incorporates Direct Data Recording (DDR), Galvanic Isolation, Analog Volume Control and Analog Preamplifier features derived from the acclaimed VEGA G2.2, ensuring a listening experience characterised by unmatched detail and precision.

Fusion DAC - A Revolution 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 utilised 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 customisation and flexibility, enabling fine-tuning and optimisation 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.

Analogue 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.

Analogue Volume Control

The VEGA S1 incorporate a highly regarded true analogue ladder resistor volume control, which is recognised as the superior method for achieving high-performance audio playback. Unlike a digital volume control, which accurately reduces the signal level but cannot address the noise floor, analogue 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 S1.

Direct Data Recording

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.

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.

Flexibility to Explore

VEGA S1 offers multiple input choices, enabling you to use your preferred music playback software effortlessly. It is 100% compatible with OpenHome based control software like BubbleUPnP and Linn Kazoo, as well as being a certified RoonReady endpoint for optimized performance within your Roon ecosystem. Enjoy the convenience of TIDAL Connect and Spotify Connect support, and experience seamless compatibility with Apple AirPlay 2 protocol. Elevate your music experience with the VEGA S1 - where choice meets premium audio performance.
