Description

M33 BluOS® Streaming DAC Amplifier

In its simplest form, the M33 BluOS™ enabled DAC/amplifier
is an ultra-high-performance streaming amplifier with superb audiophile sound.
As a BluOS enabled component, the M33 can be combined with other players in a
BluOS ecosystem of wirelessly networked music players throughout the home for
an outstanding whole-home audio system. With the employment of the new Purifi
Eigentakt™ Hybrid Digital 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.

BluOS High-Res Music Streaming

The Bar has been Raised with the Masters M33 BluOS Streaming
DAC Amplifier

Our Flagship Model Builds On Remarkable Success with
Advanced Features, Cutting-Edge Technology and High Power

Part of a growing ecosystem of compatible products, BluOS
tightly integrates hardware and software for an exceptional user experience.
The only true wireless High-Resolution multi-room system available today, BluOS
supports the new standard for High Res streaming, Master Quality Authenticated
(MQA). BluOS also supports over 20 free and paid subscription services as well
as supporting 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 never needs to
be touched.

DIRAC Live Room Correction On Board

Experts agree that room acoustics are the weakest link in
most sound systems with room reflections deteriorating tonal balance and
dynamics. Dirac, one of the most highly regarded Room Correction systems
available, not only adjusts for frequency response, but unlike other room
correction systems, it also optimizes the impulse response. By optimizing 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.
Even the most sophisticated loudspeakers can be markedly improved using Dirac
calibration. Each of the 5 Dirac memory slots can store a unique room
measurement or different frequency target curves to suit a particular musical
taste or genre. The M33 also supports Dirac’s advanced ‘Bass Control’* feature
with two independent subwoofer outputs.

Flexibility Meets Long-Term Value

In its standard form, the M33 is very complete with a wide
range of in/outputs, BluOS, Dirac, HDMI and more already fully integrated. It
will meet the requirements of the most demanding users. 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 for all of these: 6 digital inputs and 3
analogue inputs, including MM phono. Around back, the rear panel hosts two sets
of speaker outputs capable of bi-wiring and a stereo Subwoofer Output with a
fully configurable Digital Crossover. Airplay 2 and Bluetooth AptX-HD allow for
local wireless streaming from a phone or tablet.
*Some features will be available via a future software
update

Phono and Headphones Are Not Forgotten

The M33 has a high-quality MM Phono Input 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, headphone enthusiasts will delight at the sound
of the discrete headphone amplifier, which is able to drive even planar and
high impedance studio phones. With high voltage and low output impedance,
headphones will sound their best. For those who wish to enjoy their headphones but
not be tethered to a cable, the integrated Bluetooth AptX-HD module makes it
simple to possible to enjoy wireless headphones as well.

Attractive Design With Outstanding Ergonomics

The all alloy casework is elegant yet practical. The single
control knob for volume is supplemented by a color LCD 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
features and performance from the future.

Smart Home Integration Made Easy

BluOS provides hands-free control with full integration of
any Amazon Alexa or Google Assistant device. Through Airplay 2, control is also
possible with Siri. 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 multi-room 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 Apple OS are available free-of-charge and are updated regularly.
