Review for the ARIES G2 Streaming Transporter


Read a full review of the Aries G2 by Dave Clark here

Since 2014 the AURALiC ARIES Wireless Streaming Bridge has been the leader in the world of high-resolution audio streaming and it became the premier choice for bridging the gap between lossless digital music sources and your home audio system. Now, with cutting-edge transfer protocols, faster processing, enhanced isolation engineering and a redesigned chassis, the brand-new ARIES G2 Streaming Transporter raises the standard for connecting your musical world.

A New Standard in Digital Audio Streaming

The AURALiC ARIES G2 includes all the rock-solid connectivity and one-of-a-kind features found in the original award-winning ARIES and builds on them by introducing original engineering designs focused on isolation, separation and protection against interference. Not just a big brother to the ARIES, the ARIES G2 is an enhanced streaming device endowed with cutting-edge technologies and proprietary innovations. Whether on its own or working in consort with other G Series devices from AURALiC, the ARIES G2 is for music lovers who require the most discerning approach to modern streaming.

Lightning Streaming

Like all streaming-capable AURALiC products, the ARIES G2’s expansive wireless connectivity options are possible thanks to its native integration of AURALiC’s custom-built Lightning Streaming technology. Lightning Streaming uses existing Wi-Fi to create a dedicated music streaming network capable of wirelessly delivering the highest resolution musical formats available, up to DSD512 and PCM 32bit/384k. Lightning Streaming brings with it all the features you have come to expect from AURALiC streaming devices such as Gapless Playback, Memory Caching, Bit-Perfect Multi-Room and Upsampling.

Along with the ARIES G2 and the G series of products from AURALiC, they are also introducing a browser-based interface for configuring Lightning Streaming and its features which allows universal access for the first time from any smart phone, tablet or computer.

In addition to compatibility with AirPlay, the ARIES G2 is a certified Roon Ready endpoint for seamless integration with Roon software, making it one of the most flexible streamers available in Hi-Fi.

Lightning Link

Lightning Link is a low-jitter, bi-directional 18Gbps coupling that takes advantage of highspeed HDMI-type hardware connectors in order to provide a superior level of transmission control, making today’s ultra-high resolution digital music shine like never before.

Different from the other HDMI based I2S connection, the bi-directional Lightning Link opens the door to jitter-free operation of all the devices in your system. Clocking information from destination devices such as the VEGA G2 can drive the ARIES G2 timing for perfect data synchronization. Lightning Link also carries system control data for everything from volume control to processor engine setup, allowing all linked AURALiC devices to appear in a single, unified control interface.

Tesla G2 Platform

The AURALiC Tesla G2 Platform is the revamped heart of the ARIES G2. It packs a new processor that is 50% faster than the original Tesla G1 platform along with twice the system memory (2GB) and data storage (8GB). Tesla G2 not only handles the most demanding audio formats with ease, but drives the ARIES G2’s software processing engine and its advanced DSP functionality. This includes upsampling duties as well as a bigger Memory Cache for an exacting level of sonic quality and stability. As always, automatic updates keep the ARIES G2 up to date with the latest feature set and support while continually expanding its functionality as well as ensuring peak performance.

Digital Audio Galvanic Isolation

By physically separating electrical circuits while allowing data to flow between them, the Digital Audio Galvanic Isolation in the ARIES G2 offers a new level of protection against electromagnetic interference. AURALiC created two special high-speed galvanic isolators and configured them between three primary circuits in the ARIES G2. Noise-sensitive Femto Clock and digital audio transmitter systems, as well as the central processing circuit are completely isolated from each other, eliminating jitter and contributing to an unparalleled level of clarity.

Dual Linear Purer-Power

AURALiC’s Purer-Power technology already re-examined every detail of power delivery with innovative wiring and circuit designs based on the concepts of isolation and purification which was a key to the pristine operation of the original ARIES. Now, the evolutionary ARIES G2 takes that approach a step further by using two internal Purer-Power linear power supplies - separating and protecting distinct power circuits from interference. The first Purer-Power supply feeds the ARIES G2’s processing circuit, LCD display and storage – whether internal or attached via USB. The second Purer-Power pathway is dedicated to sensitive audio components such as the Femto clock and USB audio output. Both of these power supplies are galvanically isolated from each other to ensure zero EMI interference between them.

Dual Femto Clocks

AURALiC has retained the use of two Femto clocks in the ARIES G2 for incredibly detailed signal handling. The first clock drastically reduces jitter across the AES/EBU, Coaxial and Toslink outputs. But timing issues can affect sound quality from output via USB too, so there is a second Femto clock dedicated to the USB controller. No matter which route of connectivity chosen, users will benefit from extremely precise timing and low jitter thanks to these super-accurate clocks.

Unity Chassis

The ARIES G2 is housed in a completely redesigned enclosure - the Unity Chassis. It is machined from a single billet of aluminum and specifically designed for the premium lineup of AURALiC G Series products, right down to mass balancing and the shape of its foot spikes. The Unity Chassis excels at shielding the inner workings of the ARIES G2 from EMI while providing superior dampening and absorption. This detailed attention to noise reduction is evident throughout the entire G Series line of components.

Optional Internal Storage

The ARIES G2 connects to all your favorite sources of high resolution digital music, no matter where they are. However, if you prefer to store your music locally, there is an internal drive bay capable of housing any 2.5” HDD/SSD. With an internal drive installed, the ARIES G2 becomes a powerful and flexible streaming music server, ready to deliver an exceptional audio experience.
