CD22 CD player
The CD22 is the successor to and upgrade for the successful and acclaimed CD21 CD player. Every component, from the CD transport to the audio output stage, has been designed to achieve the highest possible audio performance.
The CD22 Compact Disc player is housed in an alloy heavy gauge steel chassis, which provides strength, rigidity, and screening, while being effective at damping vibrations from external sources. From the CD transport we extract the AES/EBU (balanced S/PDIF) signal and feed it to a superior SRC4392 sample rate converter (user switchable between 44.1kHz bypass, 48 kHz,96 kHz and 192kHz), which incorporates jitter suppression capabilities to ensure that the DACs receive as clean a signal as possible according to the sampling frequency elected. The CD22 uses a single high-performance Burr-Brown PCM1792 DAC – one of the best single-Bit digital-to-analogue converter/filters available. The current to voltage conversion stage ends in a single-ended output comprising a MOSFET transistor driven by an active current source (preferred to passive resistors). The CD22 contains no capacitors in the signal path: a DC-servo takes care of any DC offset present in the circuit or from the DACs. SMD technology is used throughout the design in order to keep the signal paths isolated and as short as possible.
