A major innovation behind the VEGA G2’s vivid sound quality is its unique approach to timing. Traditional DACs lock on to the frequency of a digital input signal to regulate the timing of processing and output. But that frequency is prone to errors — either introduced during transmission, or in the source itself. Those errors are called “jitter", and they’re hard to fix when you’re locked into the signal in real time.
The VEGA G2 can take a different approach, thanks to the powerful resources of its Tesla Hardware Platform. The first step is temporarily storing the incoming digital signal in memory. That way there’s no need to lock on to its frequency, and any jitter associated with it is completely removed.
Now the VEGA G2’s super-precise Dual 72fs Femto Master Clocks come into play, providing the VEGA G2 DAC circuit with a better, more reliable reference frequency with extraordinarily low jitter. (In a complete system of G2 components, this job falls to the specialized LEO GX Master Clock, for the ultimate in clocking precision and jitter reduction.)
Next, the DAC circuit uses that new reference frequency to synchronize with the Tesla platform, so that music data from the memory buffer is delivered to the DAC chip with perfect timing.
In this way, the VEGA G2’s audio output is completely independent of the digital input signal. It means the VEGA G2 is always in charge — functioning as the master clock for a signal that’s completely jitter-free.
