The
The CDA823 is an evolution of the renowned CDA822 CD-player.
While employing the same outstanding DACs and analog amplifiers
as its predecessor, double resampling and reading speed are
now introduced. Increased over-sampling of 192 kHz is used
to avoid the loss of energy and transparency in a complex
analog output filter. The CDA823 also allows for future updates
of firmware through flash programmable microprocessors.
The CDA823 uses a true 24-bit, high-resolution, dual differential,
digital to analog converter with current output for widest
dynamic ranges, fast conversion and lowest noise. Jitter distortion
arising from time errors is virtually eliminated by sample
rate converters and our precision internal master-clock. All
audio power supplies are multi-regulated. The output amplifiers
are a priority in the design of this audiophile CD-player.
Operational amplifiers with their fixed
working conditions and sound qualities can become an obstacle
when the designer wants to be in control of the final performance.
Therefore, CDA823 employs discrete class-A input amplifiers
with carefully selected operational points for the specific
electronic environment in which they have to perform. The
output circuitry provides both fully balanced and single ended
outputs.
