“dCS feels that listening tests have proven to their engineers that having a dedicated master clock delivers superior sonic results over a DAC alone acting as the system’s master clock. The current dCS clock features the latest iteration of the company’s multi-stage Phase-Locked-Loop (PLL) system, outfitted with multi-stage power regulation and housed in an “aerospace-grade machined aluminium chassis fitted with tuned acoustic damping panels [to] reduce magnetic effects and vibration.” Special crystals are employed in clock systems which are chosen for their oscillation accuracy over both short and long-term timing domains. At dCS (and many other high-end companies), these crystal oscillators are pre-aged. They are “… selected for long term stability and then individually calibrated over a wide temperature range to ensure consistent optimal performance. [The] Rossini Master Clock uses a sophisticated microcontroller system to ensure smooth frequency correction as the temperature changes, and this approach gives a more stable result than either oven-controlled crystal oscillators (OCXO) or even atomic clocks,” according to the company.”
