SUPER AUDIO FOR ALL CD’s
The Super Audio Compact Disc offers a significant improvement
in sonic performance when compared with a standard CD. SACD uses
a fundamentally different approach to transferring the analog
musical waveform into the digital domain for storage on the disc.
This is called Direct Stream Digital, and is widely considered
to be a fundamentally better approach to digital encoding. This
requires very high speed processing that simply wasn’t available
at the birth of the CD format. This high data rate process avoids
the quantization errors inherent in the Pulse Code Modulation
process used for the traditional CD and DVD. Extended high frequency
response, enhanced detail and a more analog-like sound quality
are often stated improvements of SACD over CD.
Many of us still have extensive CD collections, however, and
luckily the M5 has sophisticated circuitry designed to also get
the best possible sound quality from your existing CD recordings.
In addition, the M5 includes an HDCD decoder which can increase
the dynamic range of CD by 6dB with specially encoded and widely
available CDs. CDR and CDRW recordable discs are fully supported,
and even MP3 and WMA can be played on the M5 CD/SACD Player offering
many hours of playback from a single disc.
But the SACD format also offers the possibility of 5.1 surround
sound playback, and the M5 is equipped to take full advantage
of these exciting new multi-channel recordings. We have even included
comprehensive bass management (redirection) for the 5.1 output.
Several popular speaker configurations can be easily accessed
from the front panel controls and navigated via the VFD display.
A higher level of fine tuning is available via the Composite Video
output using the M5’s On Screen Display. This video output
is also useful for managing MP3 playback. Since we expect most
M5’s to be used in music only systems, the video circuit
can be switched off to afford the cleanest possible audio performance.
LUXURIOUS DESIGN
The design brief reads: “The industrial design must create
a physical presence that is powerful, dynamic, and solid, yet
refined and elegant”. We wanted a design that will still
look fresh and new a decade from now, a design with classic proportions
and understated details.
Intelligent use of aluminum extrusions, zinc castings, and heavy
gauge steel results in a chassis that is as rugged as it is handsome.
Innovative use of specialized coatings and plating results in
a product that will retain its good looks for many, many years
to come.
Since the high-density data recorded on SACD must be read with
absolute accuracy, vibrations from outside or from internal sources,
such as the power supply, will adversely affect sound and picture
quality. A variety of special measures have been incorporated
in the NAD M5 to suppress these unwanted vibrations, from the
carefully engineered heavy gauge steel chassis, to the vibration
isolating silicon rubber foot design.
AUDIO PERFORMANCE
Separately configured signal paths for the CD and SACD audio maintain
the highest possible levels of CD and SACD sound quality. PCM
Digital audio outputs are available in AES/EBU (balanced), coaxial,
and optical (TosLink) SPDIF formats.
The NAD M5 uses professional grade D/A converters with 24-bit,
192-kHz resolution for PCM (CD) signals, and a special DSD mode
for SACD. These premium devices are well protected from noise
caused by even minute fluctuations in current from the power supply.
Separate digital filters are employed for the SACD and CD signal
paths to perfectly compliment these uniquely different signal
formats. The level of quantization noise within the frequency
range is uniform for all frequencies and very well suppressed.
This D/A converter ensures that all the sound you hear is as clear
and noise-free as possible, regardless of recorded format.
NAD’s specially designed discrete Class A gain modules
keep all the detail in high resolution SACD perfectly intact,
and offer very low output impedance across the frequency spectrum.
These are the same high performance modules first seen in the
M3 preamplifier stage, with distortion levels that are at the
lower limits of measurement combined with ample undistorted output
current to effortlessly drive even long cable runs. A set of balanced
stereo analog outputs are included for very long runs and easy
integration with professional studio equipment.
The audio stage of the M5 is fed from a separate linear power
supply utilizing a specially designed C-core transformer for the
lowest possible noise and best supply regulation. The mechanical
and digital circuits have their own independent NAD designed switch
mode supply.
Digital Bass Management is available for the SACD surround sound
format. This prevents bass frequencies from overloading and distorting
your speakers by ‘redirecting’ them to your subwoofer
which is specially designed to handle the lowest octaves. When
playing Super Audio CD sources, it is possible to preset 5.1 speaker
configurations. The crossover point is selectable with 12 dB high
and 24 dB low pass filter slopes.
