M23 V2 Stereo Power Amplifier
The NAD M23 V2 Stereo Power Amplifier is built for listeners who want true high-end power with studio-grade silence and control. Using second-generation Purifi Eigentakt™ modules and NAD’s HybridDigital™ design approach, the M23 V2 delivers exceptionally low distortion, precise timing, and stable imaging—so your speakers sound more transparent, more dynamic, and more “locked in” from top to bottom.
A great match to the NAD M33 V2
With 200W per channel into 8 ohms and 380W per channel into 4 ohms (continuous), the M23 V2 confidently drives demanding loudspeakers while staying composed at any listening level. Switch to bridged mode and it becomes a formidable 700W mono amplifier—ideal for dual-mono setups, bi-amping, or pushing ultra high-performance systems. Integration is equally refined: auto-sensing balanced XLR and RCA inputs, a three-position gain control, and an intelligent 12V trigger with delay make it easy to match with a wide range of preamps and multi-amp systems.
The NAD M23 V2 is part of ListenUp's NAD Power Amps Collection.
What It's Good At:
- Delivering effortless, high-current power that keeps demanding speakers controlled and articulate
- Revealing micro-detail and space with ultra-low noise and vanishingly low distortion
- Maintaining tight bass and precise imaging with a very high damping factor
- Scaling from premium stereo systems to dual-mono and bridged high-output configurations
- Integrating cleanly into custom and multi-amp setups with intelligent triggering and gain options
- Providing balanced and unbalanced connectivity with auto-sensing inputs for easier system matching

NAD M23 V2 Q&A:
- How much power does the NAD M23 V2 deliver in stereo mode?
- It provides continuous output of 200W per channel into 8 ohms and 380W per channel into 4 ohms, designed to stay controlled and clean at real-world listening levels.
- Can the M23 V2 be used as a mono amplifier?
- Yes. In bridged mode, it delivers 700W mono continuous output, making it a strong option for dual-mono systems or high-demand speakers.
- What inputs does the M23 V2 support?
- It includes auto-sensing balanced XLR and single-ended RCA inputs for flexible integration with a wide range of preamps and sources.
- What does “three-position gain control” do, and why does it matter?
- The gain switch helps optimize level matching with different preamps and source outputs, improving usable volume range and system synergy.
- Is the M23 V2 suitable for difficult speaker loads?
- Yes. It’s engineered for high control and stability, including high peak output current (>25A) and a very high damping factor (>800) for tighter woofer control.
- How quiet is the M23 V2?
- It’s designed for extremely low noise and distortion, including >101.7 dB SNR (1W into 8 ohm) and very low THD on both XLR and RCA inputs.
- Does it support custom-install or multi-amp setups?
- Yes. The intelligent 12V trigger with delay is built for safe, reliable sequencing in multi-amplifier systems.
- How efficient is it in standby?
- Standby power consumption is <0.5W, helping reduce energy use when the system isn’t active.
