Introduction
Here now and for the forthcoming decade: The NuPrime CDP-9 is a highly accurate CD player with an
integrated high-end DAC and preamp. A powerful DSP-based decoder that provides all Red Book
error-correction capabilities with master-clock control of the entire decoding system, thus lowering
jitter significantly. The transport’s single speed minimizes vibration and unbalanced discs. The
high-performance DAC, together with a selectable sampling rate converter for the digital output (up
to 32bit/768kHz and DSD512) converts the CD format to either SPDIF at highest sampling rate or
DSD format up to DSD512.
Features
Highly Accurate CD Playback
•
A powerful ARM chip LPC2103F CD reads, writes and controls error correction
•
Philips SAA7824HL high-end laser reads/writes head control and decodes chips
•
Supports CD-DA CD-R, CD-RW
• Algorithm reduces digital interference and jitter
A Reference Class Preamp
•
Advanced, FPGA-implemented, switched-resistor ladder network for controlling
volume with a single resistor in the signal path at any volume setting
•
Individually adjustable volume on each input for precise source-level matching
•
Volume adjustments in 99 precise 0.5dB increments. Full microprocessor control with
memory retention
Sampling Rate Converter
•
The sampling rate of any digital inputs, including CD playback, can be converted up or
down between PCM and DSD, from 44.1kHz to 768kHz or DSD64 to DSD512
•
The conversion is achieved by up-sampling to mega hertz before down converting to
the targeted sampling rate with ultra-low jitter and distortion
