Primare CD21 CD Player
The Primare CD21 CD player uses an advanced DVS mechanism. As with all Primare units, the CD21 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. The front panel design isolates the display circuitry from the audio circuitry to avoid interference.
Digital to analogue conversion in the Primare CD21 CD player is performed by two excellent Burr-Brown 24bit/192kHz PCM1738 DACs, configured in an internally balanced topology to perform a THD cancellation process. Each DAC chip is dedicated to either the left or right channel and contains two DACs, which carry the same signal with opposite phase. On the receiver side the signals are mixed, and since any interference that has arisen during the transmission will be present in both lines with identical phase, such noise and distortion products are cancelled out leaving only the pure original signal.
Primare’s uses a forensic approach to ensuring that clean power is supplied throughout the design. In the Primare CD21 CD player an internal mains filter ensures that any high frequency disturbance is removed before it reaches the power transformer, which is placed as far away as possible from the delicate analogue circuits. The player incorporates a fantastic R-core transformer with separate windings for all of the player’s different power requirements (mechanical, analogue, digital etc) – eight in all! Each is individually regulated in ten steps to ensure that enough power is constantly available. For the critical analogue audio stage, the player incorporates ultra-fast discrete power regulation, ensuring that enough regulated power is available for even the deepest sonic transient that can be recorded on a compact disc. This power supply configuration gives the player the usually extremely high signal to noise ratio allowing you to take full advantage of the dynamic range possible with CD. Power in standby mode: analogue audio sections are supplied with mains power in standby mode. This means that no run-in time is necessary for the player when activated from standby mode. Its performance will be the same as if it were left in operating mode continuously.
Although the Primare CD21 CD player is flexible enough to work with virtually any other equipment you have in your system, it is ideally suited for use with the Primare I21 Integrated Amplifier. A particular benefit of using the CD21 with a Primare preamplifier is that you can control your entire system with a single remote control, to give you a fully integrated system with the simplest possible user interface.
