About the NAD Masters Series M33

A versatile and powerful streaming amplifier

The NAD Masters Series M33 has an incredible list of features that make it an ideal centerpiece for a two-channel audiophile sound system. It produces a stable 200 watts per channel into an 8-ohm load or 380 per channel into 4 ohms. That gives you lots of clean power to work with, as well as compatibility with a wide range of speakers. This amp offers plenty of analog and digital inputs for making wired connections, along with multiple wireless music streaming options. And it offers built-in room correction and optional voice control.


The very versatile NAD Masters Series M33 offers 200 watts of power per channel, plus multiple options for playing music via wired components and wireless streaming.

A wealth of streaming features

If you like the convenience of wireless streaming, this amp has you covered: Bluesound's proprietary BluOS operating system gives you easy app-based access to popular online streaming services like Spotify®, Qobuz, and more, as well as your personal library of downloaded music, including high-res audio files. You can also enjoy lag-free multi-room wireless music when you add on Bluesound speakers and components for other rooms. Apple® AirPlay® 2 lets you stream directly from an iPhone® or iPad® and ask Siri to play Apple Music.

Two-way Bluetooth means you can play the audio from apps on your mobile device through the M33, or send music from the amp to compatible wireless speakers or headphones.

Convenient connections

For analog music fans, the M33 offers unbalanced RCA and balanced XLR inputs. A built-in phono stage lets vinyl lovers connect a turntable with moving magnet or moving coil cartridge. 

And there are a plethora of handy digital connections on the rear panel, including:

  • dual optical and dual coaxial inputs for connecting a CD player, Blu-ray player, or output from a compatible TV

  • USB Type-A for connecting a thumb drive loaded with music

  • AES/EBU XLR input

  • HDMI ARC for enhancing dialogue, music, and sound effects from a compatible TV

  • Ethernet port for making a wired connection to your network

The back panel features two sets of binding posts for connecting pairs of speakers. If you want extra bass, the M33 includes two mono RCA outputs for connecting powered subwoofers. There's also a headphone jack and analog preamp outputs.

Advanced room correction

The M33 includes Dirac Live — one of the industry's best room-correction platforms. This software-based system uses the included calibration microphone to take precise acoustic measurements of your room, and creates a customized correction curve that fine-tunes the output of your speakers and subwoofers. You get smooth, clear sound that's uniquely tailored to your space. 

Innovative Class D amplifier technology

This amp pushes Class D amplification performance to new limits thanks to HybridDigital Purifi Eigentakt™ technology. It helps the amp maintain even frequency response into lower impedance loads and minimizes the occurrence of digital clipping. This advanced design offers robust power output and accurate sound with minimal distortion, without the excess weight and cost associated with more traditional linear power supplies and Class AB output stages.
