NAD M33 integrated stereo amplifier

NAD M33 integrated stereo amplifier


In its standard form, the M33 is very complete with a wide range of inputs and outputs, BluOS, Dirac, HDMI and more. It will meet the requirements of the most demanding users. To reduce the risk of obsolescence in the future, the M33 has two MDC (Modular Design Construction) slots that allow for further expansion. NAD introduced the MDC platform more than a decade ago and allowed products to be updated with new technologies that did not even exist at the time of introduction.


Whether you want to connect digital or analog sources, the M33 is well equipped to accommodate it all: 6 digital inputs and 3 analog inputs, including MM phono. The back of the panel houses two sets of speaker outputs that allow two-wire connection and a stereo subwoofer output with fully adjustable digital crossover. Airplay 2 and Bluetooth AptX-HD enable local wireless streaming from your phone or tablet.


The M33 has a high-quality MM Phono input that is a match for specialist external units. Precision RIAA equalization, a smart infrasonic phase-break filter, and a large overdrive edge combine the best of LPs. Plus, headphone enthusiasts will love the sound of the discrete headphone amplifier, which can drive even high-impedance planar and studio phones. With high voltage and low output impedance, the headphones will sound their best. For those who want to enjoy their headphones without being tied to a cable, the built-in AptX-HD Bluetooth module also makes it easy to enjoy wireless headphones.


The all-alloy body is stylish yet practical. A single button volume control complements the color TFT touch screen. Hard boards with magnetic isopoint feet provide a solid base for multi-layer circuits and complex internal construction. The M33 uses a completely modern and fresh take on the traditional stereo amplifier with features and capabilities from the future.


BluOS enables hands-free operation with full integration of any Amazon Alexa or Google Assistant device. Via Airplay 2, control is also possible with Siri. We've put a lot of effort into making the M33 fully compatible with all leading smart home systems from leading companies such as Apple, Crestron, Control4, Lutron, KNX and many others. This means that an integrator or user can seamlessly control a BluOS multi-room music system from a common interface, along with lighting, shades, HVAC and security. All integrations are certified for reliable operation. BluOS custom apps for iOS and Android tablets and phones, as well as desktop control from Windows and Apple OS, are available for free and are updated regularly.
