M33 BluOS™ STREAMING DAC AMPLIFIER
WORLD’S MOST ADVANCED AMPLIFIER
With the employment of the new HybridDigital™ Purifi Eigentakt™ amplifier technology,
the M33 follows NAD’s long-standing tradition in identifying and developing cutting-edge
amplification technology. With a minimum of 200W per channel on tap, the result is lifelike
performance, exemplified by ultra-low distortion and noise. The measured performance is
remarkable in that it nears the limits of even the most sensitive and sophisticated test
equipment available.
The NAD Masters M33 is a true state-of-the-art audiophile amplifier in the traditional
sense yet with a distinct difference: It fully caters to the modern world where the majority
of music is delivered over the internet with an entire catalogue of recorded music readily
available at your fingertips; a great convenience. Multi-room wireless audio capability
multiplies the enjoyment.
BluOS™ HIGH-RES MUSIC STREAMING. EVERYWHERE
Unusual in a class of products often associated with complexity is the M33’s intuitive
operation, courtesy of the seven-inch touchscreen colour display combined with BluOS. NAD
considers it the most advanced network streaming and multi-room operating system available.
BluOS, the innovation leader in true wireless High-Resolution multi-room systems has a
growing ecosystem of compatible products that tightly integrate hardware and software for
an exceptional user experience.
Besides multi-room, another compelling feature of BluOS is its high-res streaming
capabilities. BluOS supports the new standard for High Res streaming, Master Quality
Authenticated (MQA). BluOS also supports some 20 free and paid subscription music
services including Tidal, Deezer, Qobuz, Amazon HD, Spotify, Amazon Music, Slacker,
TuneIn, nugs.net and many others. In addition, BluOS supports locally stored music libraries.
With BluOS, the M33 retains all the audiophile features and further adds a range of facilities
that will expand its capabilities yet simplifies ease-of-use at the same time. Operable with
the BluOS app, the supplied remote control or through hands-free control with any Amazon
Alexa or Google Assistant device, the M33’s front panel doesn’t actually need to be touched.
To expand the multi-room locations, adding additional rooms is both easy and affordable.

DIRAC ROOM CORRECTION INTEGRATED
Experts agree that room acoustics are the weakest link in most
sound systems with room reflections deteriorating tonal balance
and dynamics. Dirac Live, one of the most highly regarded Room
Correction systems available, not only adjusts for frequency
response, but unlike other room correction systems, it also
optimises the impulse response. By optimising the speaker/room
interface, music sounds more natural and lifelike.
Supplied with the M33 is a precision microphone to measure the
room at and around the listening position so your system can
be precisely calibrated for optimum performance. The result is
substantially improved musical staging, clarity, voice intelligibility,
as well as a deeper and tighter bass.
Each of the five Dirac memory profiles can store a unique room
measurement (think of the different acoustics with curtains open
or closed, different listening position, for instance), or different
frequency target curves to suit a particular musical taste or
genre. The M33 also supports independent subwoofer outputs,
compatible with Dirac’s advanced “Bass ont o ” .
MODULAR DESIGN OFFERS MAXIMUM FLEXIBILITY
In its standard form, the M33 is very complete. It features a
wide range of inputs and outputs, BluOS, Dirac Live, HDMI and
more, already fully integrated. It will meet the requirements of
the most demanding users.
PHONO AND HEADPHONES ARE NOT FORGOTTEN
The M33 has a high-quality selectable MM or MC phono stage
that rivals specialized outboard units. Accurate RIAA equalization,
a clever phase cancelling infrasonic filter, and a huge overload
margin combine to bring out the best in LPs.
Furthermore, if you are a headphone enthusiast, you’ll delight at the
sound of the discrete headphone amplifier, which is able to drive
even planar and high impedance studio headphones. With high
voltage and low output impedance, your headphones will sound
their best. If you want to enjoy headphones but not be tethered to
a cable, the integrated Qualcomm aptX HD Bluetooth module
makes it simple.
ATTRACTIVE DESIGN WITH ERGONOMIC BEAUTY
The all aluminium casework is elegant yet practical. The single
control knob for volume is supplemented by a colour TFT
touchscreen display. Rigid panels with magnetic iso-point feet
provide a solid foundation for the multi-layer circuit boards and
intricate internal construction. The M33 employs a completely
modern and fresh take on the traditional stereo amplifier, with
forward thinking features and performance.
EASY SMART HOME INTEGRATION
BluOS provides hands-free control with full integration of any
Amazon Alexa or Google Assistant device. Through Apple AirPlay
2, control is also possible with Siri.
To minimize the risk of future obsolescence, the M33 comes with
two MDC (Modular Design Construction) slots that allow for further expansion. NAD introduced the MDC platform well over a
decade ago and allowed updating products with new technologies
which didn’t even exist at time of introduction.
CONNECTION AND WIRELESS FLEXIBILITY
Whether looking to connect digital or analogue sources, the
M33 comes well equipped to accommodate 6 digital inputs and
3 analogue inputs, including MM/MC phono.
The rear panel hosts two sets of speaker outputs capable of
bi-wiring and two independent Subwoofer outputs with a fully
configurable Digital Crossover. Apple Airplay 2 and Qualcomm aptX
HD Bluetooth allow for local wireless streaming from a phone or
tablet.
Considerable effort has been spent to make the M33 fully
compatible with all the leading smart home systems from leading
companies like Apple, Crestron, Control4, Lutron, KNX and many
others.
This means that along with lighting, shades, HVAC, and security,
the integrator or user can seamlessly control the BluOS multiroom music system from a common interface. All integrations are
certified for reliable operation. The custom BluOS Apps for iOS
and Android tablets and phones, as well as desktop control
from Windows and macOS are available free-of-charge and are
updated regularly.
