Special Order




An elegant, top-of-the-line, BluOS-capable integrated amplifier with a host of features that offer maximum flexibility, excellent efficiency, and reduced noise and distortion. Also includes a phono input and a headphone output to accommodate music lovers of all kinds.

NAD M32 DirectDigital Amplifier

As the culmination of 45 years of experience in home audio design, the NAD M32 DirectDigital DAC Amplifier redefines the modern audio component system. Combining all pre-amplification and power amplification functions into a single amplifying stage, the M32 is the ultimate amp for your home entertainment system. By minimizing both noise and distortion, the M32 allows you to hear your favourite songs in rich, clear detail, giving you a music listening experience unlike any other.

Key Features:
- 180W RMS into 8 Ohms
- DirectDigital amplification
- Four MDC slots with three for customisation and expandability, all are 24/192 capable
- MM Phono Input & Single-ended Line Inputs
- Asynchronous USB 2.0 (24/192) Computer Input
- AES/EBU, Coax, and Optical 24/192 Inputs
- Dedicated headphone amplifier

Redefining the Integrated Amp

The traditional integrated amp included the preamp control centre with the power amp in a single chassis. The downside of this was the reduced flexibility and possible interference by the high voltage power circuits to the highly sensitive preamp stages caused by cramming everything into one box. In the digital age, these limitations disappear. The signal can stay in the digital domain right up to the speaker outputs, making the M32 preamp impervious to interference from the power stage. Concerns about limited flexibility are erased by NAD’s innovative Modular Design Construction (MDC), which allows a greater density of inputs as well as the flexibility to upgrade complete circuits as future technologies unfold.

The Preamp is Replaced by Software

When it comes to the M32, NAD has combined all preamp and power amp functions into a single amplifying stage controlled by software. Highly advanced mathematics determines all control functions including volume and filters. This produces a dramatic reduction in noise and distortion, bringing you much closer to both the music and the performers. Traditional volume controls that change the gain in an active analogue circuit cannot approach the transparency of the M32. It also allows ‘perfect’ tone controls that only change tone, without adding phase shift or distortion. You can also easily bi-wire or add a subwoofer(s) with the built-in electronic crossover.

DirectDigital Defined

With 2 x 180W power on tap, the M32 can make almost any speaker sing. The M32 has virtually no distortion and a damping factor that is off the chart. This is all due to the innovative DirectDigital™ Feedback Amplifier built under license from Cambridge Silicon Radio (CSR), which uses a form of digital error correction that is incredibly fast and accurate. This is a true digital amp (not just Class D) that is computer controlled and amplifies entirely in the digital domain, converting to analogue at the speaker terminals. This gives it the shortest signal path in NAD’s history.

Modular Design Offers Maximum Flexibility

Using a proprietary modular design, you can upgrade or expand your M32 as technologies emerge, ensuring a cost-effective way to keep the music “on” into the future

By placing inputs and associated circuitry on uniform upgradeable modules, the M32 can be custom tailored to cater to your exact requirements. There are a total of four MDC slots, with three being available for expansion. The preinstalled module is the SPDIF Module, including AES/EBU, 2 x Coax and 2 x Optical, all 24/192 capable. Additionally, there is a USB B port for connecting computers as well.

Thanks to NAD’s MDC technology, the M32 is ready for all future upgrades, ensuring that your system will never fall behind the times. By adding the BluOS MDC Module, the M32 becomes a member of the BluOS ecosystem, thus opening the doors to your music library regardless of whether it’s stored on hard drives or the cloud. 

Ready for Hi-Res Audio

By simply adding the optional BluOS MDC Module, the M32 becomes part of the BluOS® wireless multi-room music ecosystem. Unlike UPnP or AirPlay® which rely on middleware to translate between different platforms; BluOS is a true operating system unlimited by reliance on middleware or computers.

As the leader in high-resolution network audio, BluOS is a complete music management system that brings all your music together, whether it is on hard drives or the cloud, into one easy-to-use control app for smartphones, tablets, and laptops. It is also a wireless multi-room system fully compatible with the amazingly affordable Bluesound wireless speakers and digital music players.

Phono and Headphones Are Not Forgotten

The M32 also has 2 x Line Inputs and an MM Phono Input that sounds incredible with vinyl. Accurate RIAA equalization, a clever phase canceling infrasonic filter, and a huge overload margin combine to bring out the best in your LPs. Furthermore, if you are a headphone enthusiast you’ll be thrilled at the sound of our discrete headphone amplifier, which is able to drive even planar and high impedance studio cans. With high voltage and low output impedance, your headphones will sound their best.

Modern and Fresh

The all-alloy casework is elegant and practical. The single control knob for volume is supplemented by a TFT touchscreen display, which replaces a multitude of mechanical switches and expands the range of adjustments possible with detailed graphical readouts (IR remote is also included). Because the controls are all software-defined, you can add new controls and features by simply upgrading to new firmware. This is quite revolutionary and works hand-in-hand with MDC to create a future-proof digital music player. Rigid panels with magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction. The M32 is a completely modern and fresh take on the traditional stereo amplifier, with features and performance from the future.

Advanced software-controlled algorithms result in the shortest signal path from source to speaker to produce virtually no distortion and a damping factor of over 1,000. This technology is among the fastest and most accurate amplification and error correction available.

Master Quality Authenticated

Master Quality Authenticated (MQA) is a revolutionary end-to-end technology built into every Bluesound Player that captures and delivers master quality audio to any room in your home. All Bluesound Players include a powerful decoder and audio renderer for the MQA system. The MQA logo shown in the BluOS app indicates that the unit is decoding and playing an MQA stream or file, and lets you know that you are hearing exactly what the artist recorded and approved in the studio.

About NAD

In 1972, a new kind of audio company was born. NAD took form when a large group of audio-industry importers in Europe, all music lovers, set out to develop products that cut through the industry hype. The goal of NAD was to prove that excellent sound quality and excellent value could exist together. It was a formidable goal – some of the most reputable electronics brands of the time were unaffordable to most, while the affordable spectrum of the market was dominated by poor quality imports from global electronics giants. NAD’s founders remained undeterred and their original vision led to an inspiring story of how a group of specialty audio mavericks took on the Goliaths of the audio industry to carve out a unique place of their own.

NAD is dedicated to innovation, performance, value, and simplicity in all their products.
