C 568 CD Player - AH
Preliminary
C 568 CD Player
NAD C 568 CD Player.
The C 568 takes the superb performance of our 5-star rated
C 565BEE and steps it up to the next level. Every aspect of sonic
performance is enhanced and refined, making the C 568 the
ideal companion to our C 368 amplifier, or any system in need
of a performance upgrade.
The C 568 replaces NAD’s venerable C 565BEE. With the
worldwide acclaim and numerous awards for outstanding
performance and value, it is fair to ask why NAD would
“mess with success.” Nonetheless, NAD has never rested
on its laurels; rather development is ongoing at the NAD Lab
and new models are launched when we feel a significant
improvement has been achieved. Such is the case with the
C 568. Besides the new more refined cosmetics, the circuit
layout and component choices have been extensively updated.
The cumulative effect of these changes is dramatic, improving
low frequency slam and extension, while maintaining the pace
and timing for which the C 565BEE was so lavishly praised.
Image depth and scale are further enhanced while retaining the
timbral accuracy and lucid harmonic structure of its predecessor.

Features and Circuitry
Creating one’s own favourite compilation CD-R and CD-RW’s on a CD
ripper is becoming ever more popular, and unlike older CD players,
the C 568 will easily play these discs, even those encoded with MP3
and WMA compression. Nearly 10 hours of music can be recorded
onto one CD-R when using 128kps compression allowing ‘all day’
background music listening. We have included a number of additional
features to make your listening more enjoyable: RANDOM gives
the listener a random selection of all tracks on the disc in play, and
REPEAT allows repeat playing of either the entire disc or individual
tracks. Individual tracks can be quickly accessed using the SKIP
function (Forward and Back), and the SCAN function (Forward and
Back) gives an aural précis of individual tracks, giving the listener the
opportunity to reach specific sections of the track.
The Vacuum Fluorescent Display provides clear and understated,
yet comprehensive information to the listener. The track number is
displayed, and for those who regularly record CDs, the button displays
the current time elapsed or remaining for complete CDs or individual
tracks.
Not all digital outputs are equal. In the case of the NAD C 568,
careful attention has been paid so that best use can be made of the
ever-increasing number of products now available with digital inputs
(outboard D to A converters, AV Receivers, etc.). The coaxial output is
buffered and isolated by a transformer from the converter itself, and
the output impedance has been carefully tailored to produce a precise
75 ohms impedance to ensure perfect matching. This attention to
detail reduces the timing errors (jitter) that could otherwise distort
the digital data stream. An optical Toslink output is also provided
allowing connection to devices that only provide this option.
The Model C 568 comes supplied with the new NAD CD-8 full
function remote control, offering all of the features described
above from the comfort of your listening chair. On top of that,
the remote control handset gives you direct track access and
programming facilities as well, saving the user’s time when
they’re storing preferred song titles. Up to 20 tracks can be
programmed, with the ability to delete tracks without using
the program function by simply using the DELETE key.
Separate power regulators for the digital and analogue
sections isolate the two electrically, reducing interference
effects. Furthermore, careful layout of the PCB tracks around
the Digital-to-Analogue Converter (DAC) helps to contain RF
radiation and interference. The 24-bit high resolution Wolfson
WM8741 DAC chip was chosen for its excellent low-level
linearity and detail retrieving capabilities. A high-precision
Crystek Clock Module reduces digital jitter to unprecedented
levels for an affordable CD Player and makes it a great platform
for adding an exotic high-end DAC. Metal film resistors and
polypropylene capacitors are used in key areas to ensure a
highly accurate frequency response. Studio-quality LM4562
op-amps are used instead of the much lower grade and type
used in lesser players. Apart from the single-film type output
capacitor, no other capacitors are used in the signal path. The
output impedance is very low at 150 ohms, making the NAD
C 568 less sensitive to cables or the ancillary equipment it is
partnered with.
We urge you to listen to the NAD C 568 with a wide range
of program material and with the best ancillary equipment to
fully appreciate the refinement of this modest looking – and
inexpensive by high-end standards – CD player. You can
spend a lot more money for a CD player, but we think you’ll
have a difficult task finding a more musically complete and
rewarding performance than that offered by the NAD C 568.
A new benchmark has been set.
