The 32-bit ESS Sabre DAC as used inside the 8300CD continues to have a reputation as the best-sounding DAC chip available, and most CD players that use it are much more costly designs. In terms of the way it measures, its distortion figures are extraordinarily low. Around the DAC there are extensive measures to reduce jitter to vanishingly low levels, of a nature you’d expect to see only in much more expensive players.
The conversion process within Audiolab 8300CD results in the 512 DAC elements (256 DACs per channel) each operating at 84.672MHz – all digital audio sources, whatever the sample rate, are upsampled or oversampled to this frequency. This results in a conversion process that is switching 3840 times higher than the typical audio upper bandwidth of 22kHz. Without this Digital upsampling technology, the analogue filters would likely affect frequencies at or near the audible range, resulting in unwanted level and phase variation within the audio band.
