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.
Analog Preamplifier
The VEGA S1 retains the successful analog 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.
Analog Volume Control
The VEGA S1 incorporate a highly regarded true analog ladder resistor volume control, which is recognized as the superior method for achieving high-performance audio playback.
Unlike digital volume control, which accurately reduces the signal level but cannot address the noise floor, analog 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 (DDR)
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.
