Leo GX.1

Released June 2020 as part of the AURALiC Series G2.1 Upgrade, the Leo GX.1 builds on their original Leo GX model and is their superb reference master clock, providing trademark levels of performance in digital audio clocking.

Offering so-called "beyond-measurement" levels of precision, results detected while listening include a much wider sound stage, pinpoint instrumental accuracy, and dynamic range beyond expectation.

By circumventing the DAC’s internal clock, shielding the unit from noise with an internal copper enclosure, and utilising a new advanced multi-spring suspension system (available on all G2.1 products), the updated Leo GX.1 will dramatically enhance your listening experience.
