The M33, a BluOS™ enabled DAC/amplifier that can serve as the heart of a reference whole-home system. Or it can be combined with other players in a BluOS ecosystem of wirelessly networked music players throughout the home for an outstanding whole-home system.
With the employment of the new Purifi Eigentakt™ (self-clocking) Hybrid Digital amplifier technology, the M33 follows NAD’s tradition in 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. It fully caters to the modern world where the majority of music is delivered over the internet.
BluOS supports High Res streaming, Master Quality Authenticated (MQA) and over 20 free and paid subscription services and locally stored music libraries. Operable with the BluOS app, 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.
Dirac adjusts for frequency response but unlike other room correction systems, it also optimizes the impulse response. Dirac comes as standard on the M33 with corrections possible up to 500Hz. Supplied with the M33 is a precision microphone to measure the room at and around the listening position so your system can be calibrated for optimum performance. Each of the 5 Dirac memory profiles can store a unique room measurement (think different acoustics with curtains open or closed, different listening position), or to suit a particular musical taste or genre.
The M33 is very complete with a wide range of in/outputs, BluOS, Dirac, HDMI eARC and more already fully integrated. To minimize the risk of future obsolescence, the M33 comes with two MDC slots that allow for further expansion.
Another feature of BluOS is its multi-room and high-res streaming capabilities with full MQA decoding support from a local NAS or shared drive, but also from internet streaming audio services such as Tidal, Deezer, Qobuz and more. Music services such as Spotify, Amazon Music, Slacker, TuneIn, nugs.net are also supported.
The M33 comes well equipped: 5 digital inputs and 3 analog inputs, including XLR Balanced, MM and MC phono. 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.
The M33 has a high-quality MM/MC Phono Input that rivals outboard units. Accurate RIAA equalization, a clever phase cancelling infrasonic filter and a huge overload margin combine to bring out the best in LPs. 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 enjoy wireless headphones, too.
The all-alloy casework and a single control knob for volume is supplemented by a color TFT touchscreen display. Rigid panels with magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction.
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. The M33 is also compatible with the Roon music platform.* 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.
