Like all streaming-capable AURALiC products, the VEGA G2’s expansive fuctionality and connectivity options are thanks to its native integration of AURALiC’s custom-built Lightning Streaming technology. Lightning Streaming uses your existing network to create a dedicated music streaming environment capable of processing and streaming the highest resolution musical formats available, including DSD512 and PCM 32bit/384k. Lightning Streaming brings with it all the audio network functionality you’ve come to expect from AURALiC devices too, like Gapless Playback, Memory Caching, Bit-Perfect Multi-Room, and Upsampling.

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 I2S standard, 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 example, providing perfect data synchronisation. 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.


Jitter-Free Operation

The union of AURALiC’s Lightning OS, the Tesla Platform and our 72fs Femto Master Clock leads to a new trick hiding up the VEGA G2’s sleeve: it’s a DAC that’s always in charge. While DACs until now have relied on DPLL circuitry to lock on to the input signal’s frequency, the mVEGA G2 has no such limitation – a first in the audio industry.

Lightning OS takes full advantage of the Tesla Platform’s considerable resources by buffering enough data to make the input signal’s frequency irrelevant, allowing the VEGA G2 to govern all processing with that super-accurate 72fs Femto Master Clock. It’s a configurable setting too, from 0.1s to 1s, so a smaller buffer size may be set for higher quality sources.

Digital Audio Galvanic Isolation

Physically separating electrical circuits while allowing data to flow between them, Digital Audio Galvanic Isolation in the VEGA G2 offers a new level of protection against electromagnetic interference. We’ve designed a high speed galvanic isolator that’s configured between primary circuits in the VEGA G2. The noise-sensitive D/A converter, Femto Clock and analog circuit are isolated from the central processing circuit, eliminating EMI noise and contributing to unparalleled sound quality.

Full Passive Volume Control

Years of development at AURALiC have resulted in yet another brand-new feature appearing in the VEGA G2 – a high-performance, low power, fully passive volume control. The fact that most relays need to draw power whether their status is ‘closed’ or ‘open’ is not only inefficient, but their always-energized coils also generate significant levels of EMI noise, adversely affecting sound quality. The eight coil-latch relays driving the VEGA G2’s R-2R resistor ladder attenuator network draw no current once set. That fully passive, zero-current system noise. It’s an expensive solution to construct, but when the goal is precise control and uncompromised sound quality, it’s worth every penny.

ORFEO Class-A Output Module

Inspired by the classic Neve 8078 analog console circuit design, the ORFEO Class-A Output Module found in the VEGA G2 is capable of driving various loads, matching the characteristics of different power amplifiers. ORFEO uses small signal components with excellent linear characteristics, thermally balanced and biased into Class-A to achieve open loop distortion of less than 0.001%. In the VEGA G2, ORFEO has been optimized for lower noise while maintaining the ability to drive 600ohm loads without increasing distortion.

Dual Low-Noise 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. The ARIES G2 takes that approach a step further by including two internal Purer-Power linear power supplies, separating and protecting distinct power circuits from interference. The first Purer-Power supply feeds the VEGA G2’s processing circuit, LCD display, and network interface. The second Purer-Power pathway is dedicated to sensitive audio components such as the D/A converter, the Femto clock, and the analog circuit. Both power supplies are galvanically isolated from each other to ensure zero EMI interference between them.

The VEGA 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 mAURALiC 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 VEGA G2 from EMI and providing superior dampening and absorption, reflecting the obsessive attention to noise reduction throughout the G Series.
