AURALiC Altair G2.1 Digital Audio Streamer
The AURALiC Altair G2.1 Digital Audio Streamer is a fully-featured digital & analogue source component. The ALTAIR model name has always been synonymous with that of extensive features and functionality. ALTAIR G2.1, however, marks a new chapter, as it’s the first time the ALTAIR concept has been incorporated and elevated into AURALiC’s world-renowned G2.1 series, combining the concepts of extensive features with that of top-quality performance.
AURALiC Altair G2.1 Digital Audio Streamer, like its G1 counterpart, provides every function and feature from AURALiC, but in one compact, ultra-quiet box, in line with the G2.1 ethos.

Powerful Preamplifier Functionality
As a G2.1 Series product, the AURALiC Altair G2.1 Digital Audio Streamer has been developed with properties and features that ensure its performance is considered “next-level,” and allow for it to be used as a stand-alone preamplifier. Analog Volume Control onboard, similar to that on the VEGA G2.1 and based on a resistive ladder design, provides ultra-quiet signal, no matter the input. Class A Orfeo Output Modules allow for an ultra-low-noise and low-distortion signal in the analog domain. Altair G2.1 also houses two separate all-analog inputs, completely bypassing the digital structure and maintaining a pure analog signal from input to out. The first is a line-level analog input, including home theater bypass functionality, and the second is an in-house engineered moving-magnet phono stage for an elegant, direct, and quiet connection to a turntable.
Next-Level Processing Power
With so many demands placed operationally upon the ALTAIR G2.1, the choice of processor was simple. AURALiC Altair G2.1 Digital Audio Streamer utilizes the most powerful of the Tesla platforms, which has more-than ample headroom to handle the challenging number of features and functions found in any AURALiC component. Finally, Dual Femto Second Clocks deliver precisely-timed signals, greatly reducing associated jitter. ALTAIR G2.1 can be controlled by Lightning DS (on Apple iOS devices), is also compatible with other OpenHome-based control software, and is Roon-ready as well. ALTAIR G2.1 can deliver a growing number of streaming services such as Qobuz, Tidal and Spotify Connect, with more to come soon.
Pure G2.1 Performance
AURALiC Altair G2.1 Digital Audio Streamer’s physical construction, as with all G2.1 products, includes Unity Chassis II, a stealth-silent aluminum enclosure encapsulating a highly-effective copper sub- enclosure that protects the advanced internal electronics from outside interference, a massive aluminum base, and a six-spring suspension footer system, all resulting in a quiet, sublime, musical performance.
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 Altair G2.1 Digital Audio Streamer.
Eight coil-latch relays remain entirely passive when not in use, drawing no power and producing exactly zero EMI noise. Once set, the Altair G2.1 Digital Audio Streamer’s volume control system remains electronically invisible — one more detail that helps the Altair G2.1 Digital Audio Streamer push the boundaries of sonic performance.
Turn Your Wi-Fi into a Music Streaming Ecosystem.
For the Altair G2.1 Digital Audio Streamer, they developed Lightning OS to be the highest-quality streaming environment you’ve ever heard. A meticulously-crafted software architecture designed specifically to work hand-in-hand with the powerful Tesla hardware platform found in AURALiC streaming products, Lightning OS is full of cutting-edge innovations that bring your music to life like never before. Connect to all your of high-resolution sources, take control with user apps like Lightning DS or Roon, and meet true audiophile streaming.
