NAD Electronics has unveiled two new additions to its Masters Series lineup: the M33 V2 BluOS Streaming Amplifier and the M23 V2 Stereo Power Amplifier. Both were introduced at High-End Munich 2025, and they’re not wild redesigns or headline-grabbing reinventions—instead, they’re smart, targeted updates to two already well-regarded components.
If you're familiar with NAD’s style, this release won’t surprise you. It’s all about refinement—tightening things up under the hood, improving connectivity, and offering just enough new tech to make a strong case for upgrading without starting from scratch.
The original M33 was a bit of a unicorn when it launched in 2020—a streaming amp that actually sounded like high-end gear. The M33 V2 sticks with that winning approach, but adds some new tools to help it sound even better and fit into more system types.
“NAD is the first company to address psychoacoustic timing issues along the entire signal path,” said Cas Oostvogel, NAD’s Product Manager. “With the M33 V2, we’ve eliminated distortion not just in the traditional sense, but in the way human ears actually perceive sound timing—delivering a listening experience that’s more nuanced, more accurate, and more emotionally engaging.”
The updates start with the digital signal chain. NAD has added MQA Labs’ FOQUS (for the ADC) and QRONO (for the DAC)—two new technologies that are all about improving timing and clarity during conversion. It also features the ESS SABRE ES9039PRO DAC and a new-generation ADC from ESS, both of which help reduce distortion and boost dynamic range.
Under the hood, there’s also a next-gen version of the Purifi Eigentakt amplifier module. For listeners, that means cleaner sound, especially when things get loud or complicated. It’s still a Class D amp, but one that leans more toward accuracy than raw power.
In terms of practical features, the M33 V2 now supports Dirac Live Bass Control. If you’re trying to integrate one or more subwoofers and don’t want to guess your way through the setup, this software can help get the room response right. It also includes XLR pre-outs and a higher subwoofer output level—useful if you’re planning to run the M33 V2 with additional gear or want a more custom setup.
Streaming and smart home compatibility are still strong points. The M33 V2 works with BluOS for multi-room streaming, AirPlay 2, aptX HD Bluetooth, HDMI eARC, and a variety of home automation platforms. You don’t need to ditch your current setup to make this fit—it’s designed to play nice with others.
Where the M33 V2 is all about combining functionality into one box, the M23 V2 is focused on doing one thing well—amplifying power—and doing it quietly and reliably.
This version carries over much of what worked in the original, but updates the Purifi Eigentakt module for better performance. It’s rated at 200 watts per channel into 8 ohms, and it can be bridged to push out up to 700 watts into one channel if you need more headroom.
It’s not flashy, but it’s got some thoughtful touches. For example, the new 12V trigger output includes a timed delay. That might sound small, but if you’re stacking multiple amps or managing power across a large system, it helps avoid surge spikes and startup headaches.
You’ve also got both balanced (XLR) and single-ended (RCA) inputs, which makes the M23 V2 easy to slot into just about any setup. Whether you’re pairing it with the M33 V2, the M66 preamp, or something entirely different, it’s ready to go.
One of the nice things about this launch is that NAD isn’t locking you into a closed system. The M33 V2 and M23 V2 are clearly designed to work well together, but you can use either one on its own. The M33 V2 makes sense as a standalone all-in-one solution for two-channel listening. But if you want to scale things up, adding the M23 V2 gives you more power and flexibility without reworking the whole system.
They also share the same Masters Series design—a clean aluminum chassis, magnetic iso-point feet, and a build that looks and feels serious without being flashy. These aren’t meant to be showpieces in a boutique hi-fi setup; they’re built to be used and integrated into real systems.
Both models are set to launch on August 11, 2025. Here’s how the pricing breaks down:
