An Elegant, Top-of-the-line, BluOS™ Ready Integrated 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. Thanks to NAD’s MDC technology, the M32 is ready for all future upgrades, ultimately 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. 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.
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 new 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.
Modular Design Offers Maximum Flexibility
By placing inputs and associated circuitry on uniform replaceable modules, the M32 can be custom tailored to cater to your exact requirements. There are a total of 4 MDC slots, with 3 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.
The Preamp is Replaced By Software
As previously revealed, when it comes to the M32 we have 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, and brings 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; there is no extra circuitry to get in the way. Plus, you can easily bi-wire or add a subwoofer(s) with the built-in electronic crossover.
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.
Quickly becoming 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 a MM Phono Input that sounds incredible with vinyl. Accurate RIAA equalization, a clever phase cancelling 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.
With 150W x 2 power on tap, the M32 can make almost any speaker sing. More importantly, 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.
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, we 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.
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.
