Leo GX applies all the engineering tips & tricks of its G Series brethren to the singular task of providing the perfect environment for one of the most advanced clocks available in high-end audio. LEO GX is in fact two clocks, each temperature-controlled or consistent performance and dedicated to establishing extremely precise working frequencies for 44.1K-based signals and 48K-based signals. The exact operating frequencies of these clocks are 90.3168MHz and 98.304MHz respectively — astonishing numbers that reflect the kind of performance that AURALiC is aiming for with the LEO GX.
The familiar Unity Chassis found in G Series products keeps this Reference Master Clock well-shielded from EMI noise, and its specially designed foot spikes dampen and absorb vibrations. LEO GX is also built with two of AURALiC’s super-quiet Purer-Power linear power circuits: one for the clocks, one for the control. A new optical isolation technology makes an appearance as well, sending control signals via fiber optic cable in order to keep internal systems separate, and to minimize physical connections.
The LEO GX is such a precise clock, running at such a high frequency, that not all connectivity is up to the task of adequately delivering its feed. To help users address that issue, AURALiC has decided to offer LEO GX in two versions:
All of the engineering detail that’s gone into the making of LEO GX means that it’s an amazingly pure environment for creating a frequency that is so fine, and so precise, that traditional descriptors for jitter and phase noise aren’t detailed enough to measure this clock’s performance.
