Furthering the company’s reputation for developing high-performance source components, Auralic has launched the Altair G2.1, a comprehensively featured product, developed to account for both digital and analogue sources, delivering transformative, dynamic sound for the demanding high-performance audio enthusiast.

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.

Altair G2.1, like its G1.1 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, Altair G2.1 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. Analogue 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 analogue domain.

Altair G2.1 also houses two separate all-analogue inputs, completely bypassing the digital structure and maintaining a pure analogue signal from input to out. The first is a line-level analogue 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. Altair G2.1 utilises 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

Altair G2.1’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.
