The Absolute Sound, Mid-Priced Amplifier of The Year:NAD's C 390DD
was a standout this year not just for its terrific sound quality,
but also for its innovative technology, future-proof architecture,
and forward-looking feature-set.Gramophone: The NAD C 390DD has
grabbed itself a place on my (extremely short) list of the very
best amplifiers you can buy today. If you're in the market at this
level, you simply must have a listen to what is as impressive a
technical achievement as it is a sonic one.Soundstage, Reviewers'
Choice: Listening to music through the NAD was a lot like seeing
HDTV for the first time: a marvelous hearing of the familiar world
through a pristine pair of new ears. Ive written before about
hearing into music, but, oh man, not like this.Digital Innovation:
The NAD C 390DD is not only a new concept in amplification, but
also in audio system architecture. First introduced in the now
famous NAD M2 Direct Digital Amplifier, Direct Digital technology
has been praised for its transparent, dynamic and detailed sound
quality. Like the M2, the C 390DD has no analogue stages in the
signal path, keeping music in the digital domain right up to the
speaker outputs. All preamp functions are executed in the digital
domain without the phase shift, noise and distortion that plagues
all analogue designs regardless of price or pedigree. Its 35-bit
architecture and 108MHz master clock also make Direct Digital one
of the most accurate DAC technologies available.Modular Design
Construction: The advantages of a pure digital system are many, but
one drawback is the constantly changing delivery formats for
digital content. Each of these formats typically requires
specialized hardware and software, often with licensed IP and
content copy protection. For this reason, we place all digital
interface circuitry on easily upgradable modules. We call this
Modular Design Construction or MDC. The C 390DD comes standard with
one module, the DD USB 1 for USB interface, and open slots for two
more modules. Optional MDC modules currently include the DD HDM-1
HDMI Module and the DD AP-1 Analogue Phono module. The DD HDMI-1
offers three HDMI inputs and one output with video pass through.
This opens up the possibility of using the C 390DD as the heart of
a Video 2.0 system using the mandatory two-channel linear PCM
soundtrack from Blu-ray or DVD to make a compelling two-channel
high definition theatre presentation. Many Symphony Orchestras and
some specialty music labels are also released in HD recordings on
Blu-ray or DVD. The DD HDMI-1 is fully 3D video compatible, but
there is no surround sound decoding or video processing.The DD AP-1
module is also very innovative, using super high quality
Analogue-to-Digital conversion to make analogue sources compatible
with the C 390DD's pure digital circuitry. Using 24/192 processing,
the ADC circuit auto-ranges for the best possible resolution and
lowest noise. The phono circuit has impedance settings for both
moving magnet (MM) and moving coil (MC) cartridges with gain
automatically set. Power: The C 390DD has a very high continuous
power rating of 150 watts per channel with almost immeasurable
distortion and noise. More importantly, thanks to NAD's exclusive
Digital PowerDrive circuit sensing the speaker load and altering
amplifier characteristics, power delivery into real loudspeakers is
enhanced with the most efficient power delivery and best safety
margin. Resulting in power output that can more than triple the
rated power for short periods of time to accurately and
effortlessly reproduce musical transients. The result is that the C
390DD sounds even more powerful than its already impressive
continuous power rating.System Architecture: Since the C 390DD
performs the functions of multiple conventional components, not
only is the sound improved, but the way a music system is
configured can change as well. The C 390DD is ready for the world
of computer audio with its asynchronous USB input that can directly
stream 24/96 content from your PC or Mac, USB memory sticks and
hard drives (Fat32) are also supported with both front and rear
connections. Or add NAD's innovative C 446 Digital Media Tuner to
stream and manage your internet radio and NAS devices as well as
local FM and AM broadcasts. Naturally, traditional components like
CD, DVD, and Blu-ray disc players can all be accommodated. Even
older analogue sources and turntables can be used with the optional
DD Analogue/Phono Module.Exclusive Features: The Direct Digital
platform includes a large amount of DSP processing power, and NAD
has fully exploited this power with a toolbox full of useful
features. Even familiar features, like the volume control, benefit
from the Direct Digital platform. Perfect signal tracking and
channel balance combined with a total freedom from noise and
distortion characterize this remarkable volume control. Traditional
bass and treble controls also take on a new usefulness when
distortion and phase shift are totally absent.An 'electronic
crossover' function is also included to easily allow
bi-amplification or subwoofer integration. Frequencies from 40Hz to
200Hz can be selected with the high pass signal sent to the C 390DD
amplifier section and the low pass sent to the preamp out. One of
the major problems in any high power music system is what we call
'room modes' or 'standing waves'. The wavelengths in the bass
frequencies are so large that room dimensions disturb the even
propagation of the sound (think of water ripples in a fish tankwhen
the wave hits the tank boundary a reverse interference wave is
produced). The result of this effect is that certain bass notes are
reinforced and become much too loud, making the bass sound 'boomy'.
This effect actually changes the perception of the harmonic
structure of the bass instruments and spoils the illusion of
listening through to the acoustic space of the recording. Our
simple solution is what we call Room EQ. Playing back a supplied
test tone sequence allows this problem to be easily tamed using
your ears and the C 390DD Room EQ filters. There are six frequency
centres in the low bass region that can be cut (or slightly
boosted) to remove the 'boom' without reducing the low bass
response. The width or Q of the filter can also be adjusted to be
wide or narrow to address a number of different room
configurations.Software Defined Product: Not only is the hardware
platform of the C 390DD flexible and upgradable, but also almost
every aspect of this fine instrument is software defined and can be
upgraded. Future MDC upgrade modules are in the works to add new
features and functions. Existing features can be upgraded with a
simple software update. The C 390DD comes standard with eight
inputs, and with the optional MDC modules, this can be expanded to
14! Inputs can be activated or hidden, and can be renamed to
reflect the specific source component attached. Listening Mode,
Polarity, and SoftClipping can all be easily selected and adjusted.
RS-232, IR Inputs/Outputs and 12V triggers all make integration
with home automations systems simple and effective.The Future
Begins Now: Small footprint, large power, low energy consumption,
future-proof upgradability, software defined operation, backward
compatibility, easy integration and a new high definition system
architecture. All this and more is combined with what is arguably
the most accurate DAC/amplifier ever devised in this C390DD Digital
Amplifierradical yet, affordable package. Now is the time to
update, upgrade and upend your preconceived notions of what a music
system looks and sounds like.The following are the C 390DD's
