Empirical Audio's Pace-Car
Empirical Audio's Pace-Car Reclocker ($1100—2300, depending on number of clocks installed) is designed to reduce the jitter of any source to "inaudible levels." Empirical's Steve Nugent said the device is primarily intended for USB, WiFi, and network devices such as the Sonos and Squeezebox. "The pace-Car is inserted between source and DAC, it can either provide a master clock to the source or accept the source's data stream and 'bracket' the rate of the stream. No modifications to the source are required."
