Powerful Processing

The Aries S1 has undergone a significant evolution, transitioning from a streaming transport or bridge to a robust streaming processor. With its advanced onboard processing capabilities, Aries S1 now offers a plethora of processing features aimed at optimising the audio signal.

Leveraging its onboard Tesla G3 platform, the Aries S1 processes the signal, effectively removing jitter and artifacts before applying user-selected processing features to enhance the audio quality. The processed signal is then output via USB, AES, coaxial or optical digital connection, ensuring an enriched listening experience that remains faithful to the original source.

Frequently Asked Questions

No. The Aries 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 the Aries S1 and your router. There are lots of potential solutions. You could use an inexpensive wireless bridge to adapt the Aries 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.

No. The Aries S1 supports external USB and NAS storage.

The original Auralic Aries was described as a “streaming bridge”. The Aries G1 and G2 series models adopted the term “streaming transport”. They could stream music from various Internet services and play music stored on internal drives or external NAS or USB drives.

The Aries S1 (and the Aries G3) are described as “streaming processors” for two reasons. Firstly, they do not just stream. They also have multiple digital inputs which can be used to connect other digital sources. Secondly, they have advanced audio processing onboard which can adapt the sound to better suit your room, speaker layout or taste.

The warranty covers defects in materials and workmanship for a period of 2 years.
