AURALiC introduces a category-wide update to its award-winning G2 and GX Product Range: Series G2.1/GX.1. The G2 Series now stands as one of AURALiC’s most successful projects. The effects of this effort have served as an important lesson to the team: that digitally oriented audiophiles prize above all else: sonic performance, industrial design, and diversity of features in their purchases. While the success of the G2 products proved a welcome chapter, the AURALiC team, in its innovative spirit, feels that it’s time to further the series in terms of its capabilities, both in the realm of hardware and software.

Auralic Sirius G2.1 Upsampling Processor

The G2.1 Series casework now features a double enclosure, or “chassis-within-a-chassis,” where the outer casework is manufactured from high-grade aluminum and an additional internal enclosure is made from copper. These design revisions enhance EMI shielding, providing an audible improvement to performance. A new, sculpted metal base provides a high-mass, heavyweight foundation for the G2.1 / GX.1 series, bonded to the enhanced four-foot assembly. This substantial base adds overall mass to the product and further builds on AURALiC’s modest elegance and improves the sound of the product overall.

Enhanced Suspension System

The balanced weight distribution design found internally in the original G2/GX layout remains unchanged, but a newly designed suspension spike system further isolates the product from external mechanical vibration. Potentially harmful vibrations are absorbed within the six-coiled-spring, acoustically calibrated core of each foot, with each spring tuned to a different tension point, resulting in greater sound clarity and a more open sound field through vibration damping at separate frequencies, yet again providing for enhanced sonic performance.
