silver series
performance value simplicity
NAD is recognised as a leader when it comes to
sensible yet unreservedly high performance audio.
These Silver Series components are some of the
most ambitious and sophisticated designs ever
offered by NAD.
The emergence of digital signal processing and multichannel stereo challenged our design team to apply
NAD’s traditional values of performance, value and
simplicity to a new generation of technology. The
Silver Series of components combine our expertise
in analogue audio technology with cutting edge digital
engineering to produce world class performance.
Designed in Scandinavia, Engineered in London and
Toronto, and manufactured in the United States and
Denmark with help from our Hong Kong Production
Engineers, these sophisticated components represent
an international effort by a dedicated group of audio
enthusiasts.
Each component in the Silver Series represents the
benchmark against which all other NAD models are
measured. Our THX Ultra certified Surround Sound
processor and amp are capable of recreating an
eerily real sound field when fed with today’s best film
soundtracks. Music gains a palpable presence in
your listening room. Every nuance of the sound is
reproduced with precision and passion. NAD’s
innovative engineering and sensible approach to
product design, are combined with precision
manufacturing to allow the Silver Series components
to set altogether new standards for value.
We hope you enjoy listening to your Silver Series
components as much as we have enjoyed
developing them. While each component stands
proud in its category, we think the Silver Series is
best enjoyed as a complete system. The full story of
each individual Silver Series component is chronicled
in the following pages.
the NAD silver series
performance
NAD’s tradition of creating products with “giant
killer” performance has been well established over
the last quarter century. And this reputation has
been earned by applying creative engineering
solutions and meticulous fine-tuning to every
circuit in every NAD product. Designed by music
lovers, for music lovers, NAD components consis-
tently deliver exceptional performance that brings
you closer to the music. It is our strong belief, that
when a product doesn’t deliver an emotionally
involving and musically accurate performance, then
it has missed the primary point of its very existence!
value
We define value as getting more for less. In the
case of NAD, that’s more performance, and less
money spent. Careful design and execution,
and staying focused on what’s really important
allows NAD to consistently offer products that over-
achieve in this regard. The ability to get
performance that is very close to the “cost-no-
object” crowd, at an everyday affordable price,
is a key element in the NAD philosophy.
simplicity
What makes NAD so unique in the world? It isn’t
just an insistence on great sound quality, it is also
our sensible approach to product design and
manufacturing. By keeping our designs simple,
and by avoiding the trendy gimmicks favoured
by many of our competitors, we can offer products
that perform better, cost less, and last longer.
This refreshing approach can be summed up
in one word: simplicity.
surround sound preamp processor
The S 170 is a carefully thought out control centre that
offers superlative performance and tremendous
flexibility, combined with a very friendly user interface.
Extensive input switching capabilities for video sources,
digital sources, and analogue sources can easily
control even the most complex and sophisticated
Home Theatre systems. The clear front panel display
gives instant feedback about operating status and is
complemented by a simple but sophisticated video
on-screen-display (OSD). A unique memory system
stores all parameters for each individual program
source, making everyday operation simple and
straightforward for every member of the family.
Based around a unique modular concept, the S 170
can be updated to new future formats simply and cost
effectively. The complete digital processing section of
this pre-pro is assembled as a plug in module, so that
even if a new processing protocol requires a faster
processor than is currently available, the S 170 can be
easily upgraded with the new processor. We also
include a 5.1 analogue input for multi-channel sources
not available as a digital signal, such as DVD-Audio.
Processing options include the popular Dolby
Surround modes, both ProLogic and Digital 5.1, as
well as DTS. We are also one of the first products on
the market to include the new THX Surround EX, 7.1
channel processing. Naturally, the S 170 includes full
THX Ultra certification. Depending on the source
material being played, the “highest” level of decoding
is automatically switched on. For music listening, we
have included our highly acclaimed EARS (Enhanced
Ambience Recovery System) mode to recreate the
natural acoustic space of your 2 channel stereo
recordings, or you can listen to unprocessed stereo
via either the analogue or digital inputs. There are
also “custom scenarios” that allow you to save up to
five preferred surround settings for instant recall.
This is useful for adjusting the balance of your
home theatre set up for different types of source
material quickly and repeatably without resorting
to set-up menus.
The digital performance of the S 170 is truly state-ofthe-art, with all digital circuits running from a single
master clock for perfect synchronisation of the various
circuit elements. Analogue-to-Digital, and Digital-toAnalogue conversions, are performed using professional quality AKM Semiconductor 24-bit/96kHz
converters. Any of the six digital inputs can be
assigned to any video or audio input for maximum
flexibility of system set-up. There are also two digital
outputs to allow recording while keeping the signal
completely in the digital domain and avoiding multiple
A/D and D/A conversions.
Video circuitry is also carefully engineered to allow the
convenience of video switching and control without
degrading the video resolution. Ultra wide bandwidth
(HDTV compatible) video signal paths utilise broadcast
quality amplification, and the OSD (On Screen Display)
is switched completely out of the circuit when not in
use to prevent any possible degradation of picture
quality. All popular video formats are supported
(Component, S-Video, Composite), and with six video
inputs and three video outputs almost any set up can
be accommodated.
Analogue performance is also at the highest level, in
keeping with the Silver Series philosophy. Input and
output buffer amplifiers are FET types selected for
their low noise and virtually distortion free
performance. Impedance values are carefully set to
avoid the potentially degrading effects of interconnect
cable capacitance, and the output is muted using
gold plated relays. In short, every circuit detail is
examined, tested, listened to, and tested again to be
sure maximum performance is realised.
The S 170 is also designed to be easily integrated
with other components, to form a seamless operating
system. The “bass management” system is
exceptionally flexible. An RS-232 computer interface is
included to allow interface with sophisticated control
S 170
DIGITAL SURROUND SOUND
PREAMP PROCESSOR
systems, and it can also be utilised to update the
operating software of the S 170. A second zone
stereo output is included with independent source and
volume control to allow the S 170 to send music to
another area of the home while simultaneously playing
music or movies in the primary area. Naturally, all
operating functions can be controlled via the supplied
wireless handset.
Born of countless thousands of hours in engineering
and design effort, we believe the S 170 reaches, but
does not exceed, that magic threshold where more
actually becomes less. That point of diminishing
returns where adding more only becomes more, it
doesn’t become better in any practical sense.
Extraordinary sonic and visual performance,
exceptional value, broad flexibility, and a simple yet
comprehensive user interface combine to make the
S 170 Surround Preamp Processor one of the most
exciting products we have ever produced.
S70
SYSTEM REMOTE
CONTROL
Designed to complement the Silver Series components,
the optional S 70 remote control sports a solid aluminium
body and a slimline ergonomic design. (Included with
the S 170.)
The simple, intuitive control system operates on a series
of ‘pages’ shown on the built-in LCD display, which
change to reflect the chosen function. For example, once
the CD input has been selected, the display will change
to offer relevant commands such as Play, Pause, Skip /
Scan, etc.
The perfect addition to any Silver Series system, the S 70
will also operate other NAD equipment, either directly or
via NAD Link.
multi-channel power amplifier
The S 250 has been designed to perfectly complement
the S 170 in both performance and appearance. Like the
S 170, the S 250 is THX Ultra approved. Because of the
very high levels of detail and transparency of sound
afforded by the S 170, this meant that the NAD
Engineering Group would have to do something very
special in the matching power amplifier to preserve and
enhance the performance of the Preamp Processor. The
design brief called for a powerful yet reasonably compact
amplifier that could easily drive the complex load
presented by today’s best loudspeakers. In keeping with
NAD’s “Music First” philosophy for home theatre
products, the S 250 would also have to measure up to
the extraordinarily high musical standards set by our own
S 200 and S 300 Silver Series amplifiers. The unique and
sophisticated design of the S 250, more than
accomplished all of these goals.
The S 250 is based on 5 identical “monoblock” amplifier
modules, each with its own heat sink and protection
circuitry. These individual amplifiers share a power supply
based on a massive edition of NAD’s signature
“Holmgren” toroidal transformer, noted for its tight voltage
regulation, and immunity from DC contamination on the
incoming AC mains voltage. Heavy duty voltage rectifiers
and low ESR smoothing capacitors combine to give the
amplifier modules a nearly ideal low impedance source of
DC voltage that contributes to the very high damping
factor and excellent signal-to-noise ratio of the S 250
design. Unlike many competing designs, the
S 250 employs one very large power supply rather than 5
small power supplies. The advantage to this approach
under real world operating conditions is obvious: any
individual channel has access to a reservoir of current
sufficient to drive all five channels on a continuous basis.
With musical and motion picture program material, it is
highly unlikely that all channels would require full power at
the same time, thus allowing individual channels to
provide far more power than their already ample 125
watts continuous rating with all five channels driven
simultaneously. In fact the S 250 can easily supply 200
watts of power per channel with only two channels driven
continuously .
But a power amplifier at this quality level must have more
than just brute strength to be successful. It must also
have performance that can unravel the smallest musical
detail and present it in a cohesive and convincing way to
the listener. The S 250 employs sophisticated circuitry to
achieve these sonic attributes. A differential Pure Class A
input stage using precisely matched FETs (Field Effect
Transistors) imparts a wonderfully warm sound with a
grain-free upper midrange and treble response. Glass
epoxy circuit boards, precision metal film resistors and
film type capacitors all contribute to the precise sound of
the
S 250 with the additional benefit of very stable
performance over time, thus ensuring a long and trouble
free service life. The output stage of the amplifier is based
on the same high current output devices used
in the S 200, offering tremendous headroom and an
ample safe operating area to handle high current peaks
with ease.
Operating status can be monitored by individual status
LED indicators visible through the top cover of the
amplifier - green indicating normal operation, and red
when the protection circuit is activated. Gold-plated
relays are used to connect the speakers after the
amplifier has stabilised during turn on, and disconnect
the speakers at turn off or if the protection circuit is
activated, protecting both the speaker and the amplifier
from possible damage in the unlikely event of a
malfunction. A switchable Soft Clipping function monitors
power output and prevents the amplifier from being
overdriven into severe distortion - a nice safety feature if
you like to listen loud! The S 250 also incorporates a soft
start-up feature that can be activated in one of three
selectable ways, via the front panel switch, via a 12-volt
control “trigger”, or by sensing a signal at the input.

MULTI-CHANNEL
POWER AMPLIFIER
Powerful and precise, the S 250 has the ability to make
music come alive with every nuance intact, and can also
bring forth the full intensity of the best cinematic scores.
With its superb build quality and understated good
looks, this amplifier will give its proud owner many, many
years of enjoyment.
stereo pre-amplifier
The NAD Model S 100 achieves its outstanding
transparency and delicacy with power-supply quality,
pure Class-A operation of all circuitry, and carefully
considered choices of components and physical layout.
It provides seven line inputs that include two complete
tape loops for flexible dubbing, with an optional, very
high-performance MM/MC phono module to allow the
serious vinyl buff to convert one of these to a superbly
accurate phonograph input.
The new NAD preamp uses an efficient, low-noise
toroidal power supply transformer, with 10,000 µF of
very-low-ESR capacitance - more than many power
amps! This creates extremely pure, stable, noise-free
internal supply voltages, a rigid prerequisite to truly
audiophile-class operation.
From input to output the circuits of the S 100 are
engineered for very low-distortion Class-A operation, with
a vanishingly low output impedance (long an NAD
hallmark) that reduces the sonic impact of cable
impedance to near insignificance. What’s more, the
S 100 supplies its main outputs in two formats:
conventional, unbalanced RCA, and fully balanced
XLR jacks.
Unlike many consumer-audio products, the latter are true
“pro-audio” outputs able to deliver up to 20 volts to 600
ohm loads while significantly reducing susceptibility to
external hum and noise.
The preamp’s signal-routing is accomplished via reliable,
sonically transparent gold-contact relays instead of the
more common, signal-colouring electronic switching, and
it uses gold-surfaced signal-connectors exclusively, both
inside and on its rear panel.
And since the S 100 incorporates NAD-Link it can
operate a full system with the supplied remote control.
This will control the principle functions of all compatible
NAD components, including the Silver Series tuner and
CD player, and directly commands all S 100 controls and
features.
Control is also available via the optional S 70 system
remote controller.

stereo power amplifier
NAD amplifiers have long been noted for a unique blend
of power, performance, and value, a carefully chosen
balance the Silver Series Model S 200 pushes to new
heights. The S 200 exploits recent NAD advances to
combine very high power with critical-listening finesse
and real-life affordability not previously available.
The fully dual-mono S 200 delivers 225 watts per
channel (8 ohms; both channels driven; 20 Hz-20 kHz at
<0.03% THD) and offers as much as 470 watts per
channel with 4 ohm loads.
Perhaps more importantly, the S 200 is stable, defined,
and musical into even unreasonable low impedance
loads (though these are encountered often enough in the
real world!). The Silver Series S 200 may be bridged,
forming a single-channel amplifier with short-term power
reserves in excess of 1.3 kilowatts (4 ohms).
There is no magic behind this elevated performance, but
considerable and painstaking refinement. The S 200’s
massive, extremely low-noise / low-hum “Holmgren” type
power transformer is a considerable advance even over
conventional toroidal devices in both efficiency and in
freedom from internal and radiated hum. A very highcurrent output stage delivers power by way of current
reservoirs built up of multiple, smaller-value storage
capacitors instead of the far more common large-value
pair. This NAD configuration, first introduced on the
widely acclaimed Model 208THX, yields “fast” highdefinition / high-power transient capabilities, and so
reproduces terrific dynamic integrity.
The end result is musical detail, impact, and soundstage
breadth and depth that are unmatched from such an
affordable high-power amplifier - to say nothing of
numerous designs two and three times the S 200’s price.
The Silver Series S 200 incorporates NAD’s proprietary,
switchable Soft Clipping, which significantly reduces the
risk of loudspeaker damage from prolonged high-power
or inadvertent overdrive operation, as well as reliable,
sonically transparent relay protection from thermal
overload, short circuits, and other unlikely but potentially
disastrous conditions.
Input facilities, all gold plated, include unbalanced RCA
and “pro-style” fully balanced XLR jacks, which preserve
the enhanced dynamic range of the NAD Silver Series
S 100 pre-amplifier’s balanced outputs for the utmost in
signal-transfer integrity.
S 200
STEREO POWER
AMPLIFIER
dual mono integrated amplifier
Integrated amplifiers have been an NAD focus from the
very beginning: Indeed, NAD’s first international product,
the Model 3020, is remembered (and widely used!) even
today as being among the most acclaimed value audio
designs of any era. So designing a Silver Series
integrated amplifier was viewed by NAD’s engineering
team as a special task.
Deceptively simple on the outside, the S 300 deploys
advanced engineering to perform at a level rarely if ever
before reached by an integrated amplifier at this price.
First, the Model S 300 produces substantial power: 100
watts per channel (both channels driven at 8 ohms; 20 Hz20 kHz at <0.07% THD), from circuitry that literally follows
dual-mono layout from input to output. Each channel is the
mirror image of the other physically and electrically, and
even the power supply - that is, supplies - comprise two
discrete units with two, entirely separate Holmgren-type
ultra-low-hum power transformers.
This approach utterly eliminates unwanted signal
interactions, and equips the S 300 with internal power of
unprecedented stability and freedom from hum and noise.
Next, the S 300’s amplifier circuits avoid overall (“global”)
negative feedback altogether, a factor today accepted as
critical to achieving legitimately high-end sonic definition
and refinement. Nevertheless, meticulous, inherently linear
circuit design maintains the S 300’s distortion and noise
performance at a solidly “modern” level - 0.07 percent
THD+noise - that would be happily accepted for most
conventional, feedback-based designs.
Additionally, guarding this musically pure signal are
sonically transparent gold-contact relays that manage all
signal routing, in place of the more usual (and far less
costly) electronic switches. And to eliminate digital circuits
as a possible noise source, the S 300’s operational
logic/control system employs yet another, fully
independent power supply (with yet another, fully
independent transformer). Minimal wiring, carefully
chosen, top-grade circuit devices including metal-film
resistors and polypropylene capacitors, and a remarkably
high-precision, motorised volume-control all make the
S 300’s design qualify as one of the finest-sounding
amplifiers, integrated or otherwise, yet devised.
In keeping with the NAD Silver Series design concept the
S 300 incorporates a fully-balanced input among its five
line-input positions, for full compatibility with the
S 500 CD player. The Silver Series S 300 integrated
amplifier is equipped with NAD-Link inter-component
control, and is supplied with an NAD full-system remote
handset. Control is also available via the exclusive S 70
system remote controller.
S 300
DUAL MONO
INTEGRATED AMPLIFIER
stereo fm tuner
It is ever more difficult to find a sonically satisfying FM
tuner. And the few designs that do qualify are increasingly
burdened by buttons, features, and functions - too many
of them of dubious utility. NAD recognises that FM radio
remains a valuable source of music and other
programming, so the Silver Series S 400 FM Tuner was
carefully designed to fly in the face of these trends.
The S 400 supports an innovative, genuinely highperformance FM section with a deliberately simplified
interface. The S 400’s technical design is highlighted by
dual antenna inputs, each equipped with a fully
independent, low-noise, dual-gate MOSFET RF amplifier.
This very atypical arrangement avoids any possibility of
interference between inputs, while providing an invaluable
convenience to those using two antennas or an antenna
plus a cable system to maximise listening options.
Triple-stage IF filtering incorporates user-selectable
(Wide/Narrow) bandwidth, a traditional feature that
enables the S 400 to offer the best-of-both-worlds
performance: maximum quieting from weak signals, and
fully maximised audio quality from strong, closely spaced
ones. (Virtually all competitive tuners and receivers
compromise performance in these areas.)
Additional advanced elements include physically separate
and independently regulated power supplies for
analogue-audio, RF, and digital-logic circuits, and a
sophisticated, highly effective implementation of the
critical 19 kHz pilot-tone filter. There is also no use of the
inductors normally found in tuners, and this guarantees
minimum phase shifting. The S 400’s user-selectable
blend mode permits highly effective quieting of very weak
or noisy signals while still preserving substantial stereo
image.
As is quite common among digital tuners today the
S 400 provides 30 preset memory locations the user
may program to instantly recall favourite stations. Entirely
uncommon is the fact that each of the tuner’s 30 presets
store not just a station by name, utilising the
programmable 8 character display input, but also the
selected antenna input, wide/narrow IF mode setting,
and mono or stereo decoding status.
The S 400 also provides a remote control, and NAD-Link
includes the necessary interface for fully integrated
system operation.
S 400
STEREO FM TUNER
compact disc player
The Model S 500 is the latest and most ambitious in a
long line of affordable-high-end CD designs from NAD - a
family that has won an unequalled reputation for true
value, performance and simplicity.
The Silver Series player tops this family tree with a singledisc design built around an extremely accurate new 24bit digital-to-analogue converter from Crystal
Semiconductor. Even better, together with its analogueaudio output section this superb converter is fully
modular, meaning that any potential future upgrades can
be performed quickly, easily, and at minimal cost by an
authorised NAD dealer.
More immediately significant is the fact that unlike the
vast majority of CD players - affordable and “esoteric”
ones alike - the S 500 supports this outstanding
DAC with custom-engineered, purpose-designed
auxiliary circuits.
These include a highly unusual five-pole analogue filter
section and all-discrete output amplifiers yielding
exceptionally pure audio-band signals, for wonderfully
transparent musical results. Just as uncommon, the
Silver Series player supplies pro-standard AES/EBU
digital output alongside its conventional S/PDIF coaxial
digital output; both are buffered and transformer-coupled,
providing a very stable and perfectly precise 75 ohm
interface that minimises jitter and reflections.
NAD’s tight design focus on the Silver Series sonics
dictated the S 500’s meticulously engineered power
supply: Multiple sections, independent voltage regulation
for digital, analogue, and servo circuit-blocks, a topgrade toroidal transformer, and very extensive filtering
combine for remarkable freedom from hum and noise in
both analogue and digital domains.
Fully Class-A analogue stages deliver very-lowimpedance outputs, which ensure uncompromised signal
quality to downstream components. To the same end,
the S 500 complements its conventional RCA outputs
with fully-balanced XLRs.
The S 500 is an NAD CD player, so it features refreshingly
simple, easy to use controls and functions, operable both
from its front panel or via the supplied remote handset,
and a complete absence of frivolous extras. The S 500
does, however, incorporate NAD-Link for “smart-remote”
operation when used in concert with compatible NAD
master components, including the Silver Series pre- and
integrated amplifiers. Control
is also available via the optional S 70 system remote
controller.
