NAD Masters M33

The NAD Masters M33 is a superb high-end streaming 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.

According to Cas Oostvogel, NAD’s Product Manager, “The NAD Masters M33 is a true state-of-the-art audiophile amplifier in the traditional sense yet with a distinct difference: At the same time, 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. This is obviously a wonderful convenience. Then, the M33’s ability to distribute that music in a multi-room audio system adds that much more enjoyment, simplicity and value.”

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 7” 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. The latter with full MQA decoding support* from a local NAS or shared drive but also from internet streaming audio services. Among the some 20 supported services which offer high-res content are Tidal, Deezer, Qobuz, Amazon HD and others. Music services such as Spotify, Amazon Music, Slacker, TuneIn, and many others are also supported.

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 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 optimises the impulse response. By optimising the speaker/room interface, music sounds more natural and lifelike.

Supplied with the NAD Masters 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 5 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 NAD M33 also supports independent subwoofer outputs, compatible with Dirac’s pending advanced “Bass Management”.

MDC (Modular Design Construction) Offers Flexibility and 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 NAD M33 comes with two MDC 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/MC phono.

Around back, the rear panel hosts two sets of speaker outputs capable of bi-wiring and 2 Subwoofer Output with a fully configurable Digital Crossover. Apple Airplay 2 and Bluetooth aptX HD allow for local wireless streaming from a phone or tablet.

Phono and Headphone 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, headphone enthusiasts, will 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, 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 also enjoy wireless headphones.

Attractive Design With Outstanding Ergonomics

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 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.

  11. Chris T

    Richard has been brilliant throughout the process of my buying the NAD M33,he has always kept me updated on the progress of stock availability.

    When the M33 finally arrived it more than justified the wait.Integration of ROON with BluOS is excellent and the amplifier responds quickly to network commands

    however the best is the performance of the new amp modules which is excellent.

    This puts this NAD M33 product into a new category and I would thoroughly recommend buying thorough Audiologica.

  12. Anonymous (verified owner)

    A versatile and excellent sounding amplifier for the modern audiophile.

  13. Chris B

    The service from Richard has been excellent. Purchased my M33 to update my M10, the transition has been excellent in both sound quality and power. To start with had a few issues but Audiologica provided me with a replacement M33 to test with my speakers. The issue turned out to be the speakers which are now resolved. If you are thinking of purchasing high end audio equipment Audiological will be my first choice.

    Absolutely wonderful company to deal with.20 minutes after I placed the order Richard was on the phone with me to thank me for the order and to inform me that there was a slight delay because of stock issues,in all fairness it was coming up to the Easter break…. As soon as the amp was in stock he notified me that it had been shipped… half an hour after it was delivered Richard was in contact to make sure everything was ok ..Thank you so much Audiologica .
