AURALiC, innovate technologies & inspire the music

For years our original VEGA has been a favorite among discriminating listeners. Now, the all-new VEGA G2 keeps the sonic spirit of its predecessor alive by pushing the boundaries of digital music. The VEGA G2 is a high-performance Digital Audio Processor with a completely revamped architecture that excels at the conversion and streaming of high-resolution digital music formats up to DSD512. The industry’s first signal-independent “Master DAC,” the VEGA G2 is redefining the sound of digital.

A one-of-a-kind Master Clock DAC - for the ultimate in Jitter-Free Operation

Designed to Innovate, Engineered to Perform
Years of research and development have gone into the creation of the G2 line and the all-new VEGA G2, resulting in engineering innovations that set a new standard for sound quality. With a completely new internal architecture focused on advanced isolation techniques and a new approach to clocking, the VEGA G2 is breaking new ground in the world of premium digital processing. Advanced galvanic isolators and always-in-control, hyper-accurate Dual 72 Femto clocks contribute to the extraordinary clarity and precision of the VEGA G2.

Master Clock DAC
The completely redesigned architecture of the VEGA G2 allows it to accomplish something amazing: it is the first DAC ever that operates independently of the source signal’s frequency.

Unity Chassis
Designed specifically for the premium lineup of AURALiC G Series devices, the Unity Chassis is machined from a single billet of aluminum that provides the VEGA G2 with superior shielding from EMI noise, so nothing interferes with the quality of your music.

Perfectly Balanced
VEGA G2 internal circuits are physically distributed to enhance overall balance. And with specially designed foot spikes that dampen and absorb vibrations, the VEGA G2 is always rock-steady, for ultra-smooth signal delivery.

Beautifully quiet 
The VEGA G2 introduces sophisticated galvanic isolation and Unity Chassis techniques that drastically reduce the potential for electro-magnetic interference, for an extraordinarily pure, clean sound. And the VEGA G2 is a full 20% quieter than the original VEGA DAC.

Customized DAC Chip
There wasn’t a DAC chip on the market that could satisfy our requirements for sonic performance with the all-new VEGA G2. That’s why we used a modified Sabre DAC chip scheme, optimized for audio signal processing of resolutions up to DSD512. It’s just one more way we made sure everything inside the VEGA G2 lives up the premium standard of the entire G2 line.

Fully Passive Volume Control
Precise control, distortion free, noise free. The only way to get all three is to painstakingly construct a R-2R resistor ladder network — and that’s exactly what we’ve done for the VEGA G2.

Eight coil-latch relays remain entirely passive when not in use, drawing no power and producing exactly zero EMI noise. Once set, the VEGA G2’s volume control system remains electronically invisible — one more detail that helps the VEGA G2 push the boundaries of sonic performance.

Access network resources like UPnP/DLNA media servers, shared network folders, high-resolution Internet Services and Internet Radio via Ethernet.





An Integrated Family of Devices
Built around cutting-edge transfer protocols, more powerful processing, and enhanced isolation engineering, G2 is a new concept in component integration. Four specialized components, working together to deliver a premium sound experience.

Lightning Link 
Jitter-free to maximize sonic performance, Lightning Link provides single-point control of the entire G2 audio system.

Dual 72fs Femto Clock
With a dedicated, low-noise 3uV power supply to minimize phase noise and keep it as quiet as it is accurate, our 72 Femto Master Clock is amazingly precise for less jitter, and immaculate sound. Its 72 femtosecond cycles — that’s 72 quadrillionths of a second — set a new standard for signal timing. Temperature-regulated for consistent performance, this clock is always there to keep things rock-steady.

Galvanic Isolation
One of the VEGA G2’s high-speed galvanic isolators lies between the Tesla processing platform and its highly sensitive DAC circuitry. Data can flow across the isolator, even while it physically separates and shields the DAC from interference. The result is a whopping 80% reduction in noise levels compared to the original VEGA DAC.

Flexible Filter Mode
Flexible Filter Mode gives you a nuanced level of control over your audio output. Its various modes were developed using a combination of objective data models and subjective testing, with each mode offering a unique array of filters to match the sonic quality of the source. Whether it’s modes to tweak in-band ripple, out-band attenuation, ultrasonic filtering and more, you’ve always got the power to dial in the performance you want.

ORFEO Class-A Module
Inspired by classic analog circuit designs, ORFEO is capable of driving an array of loads to match the characteristics of a variety of amplifiers. Using small signal components with excellent linear qualities, thermally balanced and biased into Class-A, ORFEO has the power to drive loads of up to 600ohms while keeping noise low — open loop distortion comes in at less than 0.001%.

Smart-IR Control
Smart-IR Remote Control lets your AURALiC device map its functionality onto any remote you’d like. Just let the device know which remote you prefer, and all of its operations (play/pause, volume control, track select, etc.) can be assigned to buttons just the way you like them.

Dual Purer-Power
The Purer-Power linear power supply reduces DC current noise by as much as 90dB with its power purification module. Using a specially designed transformer and unique wiring that minimizes vibration, noise from Purer-Power is kept below 1uV across the audible spectrum, leaving you to discover the details in your music, down to the last bit.

it sounds relaxed, dynamic and sophisticated. ……they bring a breath of fresh air into any system.
Carsten Barnbeck

Sparkling, lively and dynamic: Auralic‘s new G2 ‘streaming bridge’ and DAC components score with excellent sound – and technically they bring a breath of fresh air into any system.


Complex functionality combined with manageable complexity – those are the decisive components of a successful network player. And in case you think that means we’re overlooking the sound in that consideration, it’s only because that’s a given: we expect as much from high-end devices, especially those from Auralic, which has never disappointed us in that respect. With the innovative “Aries”, the Chinese company launched the first real “streaming bridge” a few years ago – effectively a network player without D/A converter. And in doing that, Auralic flew in the face of the then-current trend: at the time it seemed that even carrots from the health food store had S/PDIF inputs. Well, almost… 

Aries G2 vs Aries 

The fact that two components are shown in our lead photo may already reveal that the new Aries G2 has retained this same two-box concept. Like the original Aries, it’s designed as a pure “transporter”, G, BUT THEY’RE GOOD! Sparkling, lively and dynamic: Auralic‘s new G2 ‘streaming bridge’ and DAC components score with excellent sound – and technically they bring a breath of fresh air into any system. which is why we’re testing it with the Vega G2 D/A converter, which is also new. However, while the G2 suffix might be interpreted as “Generation 2”, that’s not the case: the original Aries isn’t being discarded, but the new model ranks in a different league.

But there’s a further reason to consider the new Aries and Vega models “en bloc”: Auralic has come up with a number of exclusive technologies for its G2 series, including the ultra-fast Lightning Link. This interface uses HDMI connections, but is audio only, transmitting potentially enormous bandwidths (in the gigabit regions) between connected devices. And Lightning is more than just a replacement for the S/PDIF interface: since HDMI is designed to work bi-directionally, the devices communicate in a master/slave network in which the DAC plays the leading role. Its high-precision dual clocks – one of which is reserved for the asynchronous USB connection – control the Aries G2’s digital operations, resulting in extremely low-jitter synchronous data transfer between the two. 

Master of time 

Compared to the original Aries and Vega, the new G2 models have significantly increased data-processing performance: what the company calls its Tesla G1 platform uses a quad-core Cortex-A9 processor running at 1GHz, with 1GB DDR3 RAM and 4GB of storage, as is designed for automatic update downloads for future performance enhancements. That he system memory is more than doubled, as data-caching – or buffering – plays a decisive role in the Vega G2. 

Incoming signals – including those from the analog input and its associated A/D converter – are stored in a digital buffer, then clocked out to the converter chip, thus filtering out digital signal distortion and jitter components from the source or from the home network. This process requires a signal delay of about 100 milliseconds – not a problem when listening to music, the already strictly two-channel Vega G2 fails when it comes as means of listening to TV sound, for example, where synchronisation with video is required. 

The converter chip is no off-the-shelf IC, but rather a modified version of the respected Sabre DAC, manufactured by ESS in small quantities for Auralic. It handles all relevant sound formats up to DSD 512, along with DXD and MQA ,and offers a choice of four digital filters, each of which brings its own character to the music. 

After conversion, the analog output passes through a complex level control system: while Auralic is an advocate of digital virtues, it recognises that, due to the mandatory bit reduction during digital volume control, even the highest resolution digital attenuator doesn’t come close to a good analog one. The Auralic solution was a passive network of resistors and relays, each arranged in groups of eight on sub-boards, and with the two channels handled separately, under the control of a digital encoder which also ‘drives’ input selection and accesses the units menus. You can hear the calming clicking and switching of the relays deep inside the device as you turn the front panel knob, and it’s worth noting that the relays are so designed that they draw no power when they are not in use, so once a level adjustment has been made, they switch off and are silent. 

Directly downstream of this relay/resistor network is a pair of Class A output stages, also shielded to minimise interference, which the manufacturer designates “ORFEO”. By the way, the idea of separate boards for each channel is primarily for maintenance purposes: for optimum channel uniformity, resistors, relays and output stage components are selected within narrow tolerances, so should something go awry at some point due to ageing, an entire channel can be replaced with a new matched set. That kind of forward thinking for ease of repair is rarely found in devices so highly integrated devices. 

The developers also used galvanic decoupling between all relevant modules, and each section – the DAC, DSP, output stages and S/PDIF input section – has an individual power supply, reducing interference and mains distortion to an absolute minimum. 

The electronics are in housings larger and more massive than anything previously seen from Auralic: milled from solid aluminium, the ‘Unity Chassis’ enclosure rests on specially-developed sprung-loaded feet, and is fronted with colourful and razor-sharp liquid crystal displays at the front, showing information such as the selected input and level (Vega G2) or the cover of the album currently being played back (Aries G2). 

Built-in redundancy? 

After connecting up Aries or Vega, you first have to decide which server you want to use, via Auralic’s own “Lightning DS” iOS app, of which more in a moment. Any UPnP or DLNA compliant NAS or computer in the home network can be used, and thanks to RAAT (Roon Advanced Audio Transport) support, the music can also be controlled and supplied with data from Roon (see page 18). Finally, Auralic’s own Lightning OS server can be activated, which indexes any external data sources and displays titles according to advanced sorting criteria such as sound format and quality (kilohertz/bit rate). 

In a way, using both G2 components is a bit redundant, since the Vega also has streaming onboard – although this is a slimmed-down implement, for example missing wireless networking. In addition, the Aries G2 can be turned into a full-fledged music server via an optional internal hard drive or a USB drive plugged into it – another attractive trick the Vega does without. 

An (almost) perfect app 

The screens on the two units are pretty to look at, but you don’t really need them: all control is provided by Auralic’s ‘Lightning DS’ app, which has always been one of the most powerful and fluid network music remote solutions. However since the product range is now quite extensive, the manufacturer has had to change the logic of that app a little bit: previously, all component and playback requirements could be reached directly, but now there is a link in the device settings to “further options. This leads to a firmware-dependent subpage with device-specific menu items such as the digital filters or the active output –somewhat more long-winded, but unavoidable in view of the expanded portfolio. 

In this submenu, the Aries G2 allows deep interventions in re-sampling in order to adapt its high-bit audio capabilities to any lower-resolution DAC you may choose to use with it, and you can also disable its built-in digital volume control. However, when used with the Vega G2, the DAC takes full control of such matters via the Lightning connection and forbids the Aries to level anything. 

The remote app also benefits from the increased RAM of the two G2 models, making control even smoother and more fluid than with previous Auralic designs. This is particularly noticeable when using the supported web streaming services from Qobuz, Tidal or Spotify: Lightning DS imports your personal favourites and playlists into the device running the app, loading them into memory at startup, a trick the somewhat lame web apps of rivals can’t match. You can also create Tidal or Qobuz favourites and playlists directly from the remote app. 

However, the super remote app has to take a little criticism: Auralic could be a little bolder in supporting and displaying ID metatags, which at the moment are limited to the usual performer/album/ genre trio. After all, Lightning DS is already able to display the signal’s data rate in the playback view, even during web streaming via Qobuz and co. 

New life for music

In the listening room, we were instantly struck by the same transparent, dynamic and extremely musical nature we had enjoyed from previous Auralic devices such as the Altair. However, the G2 team takes these traits further, breathing new life into the music and projecting a large, three-dimensional – but never overstated – soundstage into the room. Above all this is a wealth of detail, which draws out even the subtlest nuances of performances like Adele’s “Lovesong”: we especially liked the way the sound is always silky-fine and balanced despite its incredible resolution and bandwidth. Despite its attention to detail, the G2 combination invites you to enjoy hours of relaxed music. 

As expected, the performance combination seemed a bit more confident and relaxed than the Vega G2’s internal network player, so if you want to tickle out the last ounce of emotion and fine delineation of detail, you should definitely consider the two-box solution. However, even on its own the DAC, which once again proves Auralic’s intuition for innovative technology, can rival such as Esoteric’s K-07X. 


Exclusive high-bit DAC with integrated preamplifier, complex network player and velvety-fine Class A output stage. In combination with the Aries G2 network transport it sounds relaxed, dynamic and sophisticated.
