Vega S1 is Auralic’s latest entry level audio streaming DAC. Powered by Auralic’s cutting edge Tesla G3 streaming platform, the Vega S1 inherits premium audio technologies from the acclaimed G2.2 reference products, including Direct Memory Access (DMA), Direct Data Recording (DDR), Fusion DAC, Galvanic Isolation and more.

Vega S1 features USB, coaxial and optical digital outputs for broad compatibility with other digital source components. It supports seamless streaming via Ethernet through Auralic’s Lightning DS, Apple AirPlay 2, TIDAL Connect, Spotify Connect and Internet Radio. Vega S1 is currently undergoing Roon Ready certification.

Fusion DAC

Vega S1 represents the pinnacle of Auralic’s state-of-the-art DAC technology, showcasing excellence in both hardware and software realms. At its core lies Auralic’s proprietary Fusion DAC, a groundbreaking innovation that seamlessly integrates the finest elements of discrete ladder and Delta-Sigma DAC designs.

Analogue Preamplifier and Volume Control

In addition to its advanced DAC technology, the Vega S1 incorporates analogue volume control and preamplifier features derived from the acclaimed Vega G2.2, ensuring a listening experience characterised
by unmatched detail and precision.

Pioneering Technologies

Breaking new ground, Auralic introduces two pioneering technologies in the Vega S1. These are PureDAC mode and Tone Mode adjustment.

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 utilises Direct Data Recording technology to store music signals from any S/PDIF or USB input in the past hour to Tesla G3’s system memory, allowing users to replay music from any point at any time.

Tone Mode adjustment refines the output sound character of the DAC by incorporating harmonic elements into the music signal, based on a model rooted in auditory psychology. This innovative feature enhances the listening experience, elevating the Vega S1 to new heights of audio excellence and musical enjoyment.

Frequently Asked Questions

No. The Vega S1 only has wired Ethernet. Wired Ethernet provides the most stable connection to your home network and maximises the available bandwidth.

Do not worry if you are unable to run an Ethernet cable between your Vega S1 and your router. There are lots of potential solutions. You could use an inexpensive wireless bridge to adapt the Vega S1’s Ethernet connection to your existing WiFi network. You could use Powerline adapters or WiFi range extenders with Ethernet ports. Our preferred solution is to install a wireless mesh system. These normally have one or more Ethernet ports on each mesh node to connect wired devices. Mesh systems offer the extra benefit of providing much better WiFi coverage throughout your home.

Please contact us for more specific advice and recommendations for your home network.

The Vega S1 comes with a fully functional built-in power supply. The Auralic S1 Purer-Power Supply Unit is an optional upgrade. You can purchase it with your Vega S1 or add it later. It takes the performance of the Vega S1 to the next level with additional storage capacity and regulation stages, for an even lower noise floor.

This lower noise floor, when combined with a suitably high quality amplifier and speakers, can reveal additional fine detail and spatial cues for an even more realistic and natural sound.
