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.
Like all streaming-capable AURALiC products, the ARIES G2’s expansive wireless connectivity
options are 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’ve
come to expect from ARUALiC streaming devices too, like Gapless Playback, Memory Caching,
Bit-Perfect Multi-Room, and Upsampling.
Along with the ARIES G2 and the G series of products from AURALiC, we’re also introducing a
browser-based interface for configuring Lightning Streaming and its features, allowing
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 is a low-jitter, bi-directional 18Gbps coupling that takes advantage of high-
speed HDMI-type hardware connectors 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, and it packs a
processor that’s 50% faster than the Tesla G1 platform, with twice the system memory (2GB)
and data storage (8GB) of the previous generation. 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, including upsampling duties and 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, continually expanding its functionality and
ensuring peak performance.
Digital Audio Galvanic Isolation
Physically separating electrical circuits while allowing data to flow between them, Digital
Audio Galvanic Isolation in the ARIES G2 offers a new level of protection against
electromagnetic interference. We 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
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, and
it was a key to the pristine operation of the original ARIES. Now, the 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 power supplies are galvanically isolated from each
other to ensure zero EMI interference between them.
Dual Femto Clocks
We’ve 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’s a
second Femto clock dedicated to the USB controller in the ARIES G2. No matter which route
you choose, you’ll benefit from extremely precise timing and low jitter thanks to these super-
The ARIES G2 is housed in a completely redesigned enclosure – the Unity Chassis. It’s
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 and providing
superior dampening and absorption, reflecting the obsessive attention to noise reduction
throughout the G Series.
Optional Internal Storage
The ARIES G2 connects to all your favorite sources of high resolution digital music, no matter
where they are. But if you prefer to store your music locally, there’s 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
