The 7000CDT uses a high-precision optical system with an electronic data buffer for accurate and seamless CD playback. Very similar technology to the 9000CDT, the 7000CDT uses a read-ahead digital buffer to reduce disc-reading failures, helping it plays scratched and damaged CDs that may be unreadable by conventional mechanisms. To ensure a flawless signal reaches the accompanying DAC, the coaxial output of the 7000CDT is fed from a differential line driver. The master clock is controlled by a high-accuracy crystal oscillator, enabling the digital output from both coaxial and optical sockets to exhibit vanishingly low levels of jitter (digital distortion).
