NAD M33 BluOS Streaming DAC Amplifier
Best high-end streaming amplifier for audiophiles seeking a modern, room-calibrated system.
The NAD M33 V2 is a high-performance DAC/amplifier boasting audiophile sound quality and full BluOS™ compatibility for creating whole-home networked audio systems. It features the HybridDigital Purifi Eigentakt™ amplification technology, delivering 200W per channel with extremely low distortion and noise. This unit integrates seamlessly with the BluOS ecosystem, supporting high-resolution streaming standards like MQA and over 20 subscription services, as well as locally stored music. Control is flexible, allowing use via the BluOS app, the supplied remote, or hands-free with Amazon Alexa or Siri (via AirPlay 2). A standout feature is the onboard Dirac Live Room LE Correction, which optimizes both frequency response and impulse response using a precision microphone (included) to calibrate the system for your listening environment. For future-proofing, the M33 includes two MDC (Modular Design Construction) slots for potential technology upgrades. Connectivity is extensive, offering 6 digital inputs, 3 analog inputs (including MM phono), two sets of speaker outputs capable of bi-wiring, and a stereo subwoofer output with a fully configurable digital crossover. Wireless streaming is supported via AirPlay 2 and Bluetooth AptX-HD. The M33 is also designed for easy integration into major smart home systems like Apple, Crestron, Control4, Lutron, and more.
