NAD - M23 V2 - Masters Series HybridDigital™ Stereo Power Amplifier

The culmination of over 50 years of NAD amplifier design. The M23 V2 features second-generation Purifi Eigentakt™ amplification with NAD's HybridDigital™ architecture — delivering 200W per channel into 8Ω, 380W into 4Ω, and 700W in bridged mono. THD below 0.00069% via XLR, damping factor over 800, flat frequency response to ±0.06dB, and virtually immeasurable noise and distortion. Auto-sensing XLR and RCA inputs. Three-position gain control. 12V trigger with delay.

Next-Generation Amplification, Refined

The NAD M23 V2 Stereo Power Amplifier builds on an already accomplished design with a more advanced implementation of Purifi's second-generation Eigentakt™ amplification and NAD's HybridDigital™ architecture. This is the culmination of over 50 years of amplifier design and innovation in the high-end stereo amplifier category — bringing together the most refined switching amplification technology available with NAD's own engineering philosophy that prioritises musical truth, dynamic integrity, and the ability to remain composed across the full range of what music demands.

The M23 V2 features the latest generation of Purifi Eigentakt™ modules, further reducing distortion and improving linearity across the entire output range. Subtle details and textures remain audible even during complex passages. With an extremely low output impedance and a damping factor exceeding 800, the amplifier keeps loudspeakers working accurately — so instruments sound more defined and timing remains intact.

200W, 380W, 700W — Power with Composure at Every Level

High output is only meaningful when it remains composed. The M23 V2 delivers 200 watts per channel continuously into 8 ohms, 380 watts into 4 ohms, and 700 watts continuously in bridged mono — with substantial dynamic headroom beyond these figures. IHF dynamic power reaches 260W in stereo and over 1,000W in bridged mode. Peak output current exceeds 25 amperes into 1 ohm.

This means quiet passages remain clear and detailed while louder moments retain their energy and impact without becoming congested or compressed. Complex orchestral passages, transient drum strikes, and demanding bass lines all receive the same unhurried, composed treatment — because the M23 V2 is engineered to have more power than it ever needs to call on, so it never sounds strained.

In bridged mode, the M23 V2 becomes a 700-watt monoblock — offering additional headroom for larger systems, more demanding loudspeakers, and bi-amplified or multi-amplifier configurations. A pair of M23 V2 units in bridged configuration transforms any system into a reference-level monoblock installation.

Virtually Immeasurable Distortion — THD < 0.00069% via XLR

The M23 V2's distortion figures are not merely impressive — they are at the limit of what measurement equipment can resolve. Total harmonic distortion from 20Hz to 20kHz is below 0.00069% via the balanced XLR input and below 0.0013% via the single-ended RCA input. These are figures that make the concept of audible amplifier character essentially meaningless — the M23 V2 adds so little of its own voice to the signal that what you hear is the recording, the loudspeaker, and nothing else.

Frequency response from 20Hz to 20kHz is flat to within ±0.06dB — a specification that confirms the M23 V2 delivers equal fidelity at every frequency across the full audible range. Channel separation exceeds 115dB via XLR at 1kHz.

Consistent Performance with Any Loudspeaker

Loudspeakers place varying, often unpredictable demands on an amplifier — particularly at low frequencies where impedance can drop well below the nominal rating. The M23 V2 is engineered to respond reliably across all of them. Wide bandwidth, low distortion, and high current capability — confirmed by peak output current exceeding 25A into 1 ohm — allow the M23 V2 to deliver consistent output across different speaker types and loads. The result is tighter bass, clearer separation between instruments, and a presentation that remains composed even when the music becomes most demanding.

Integration Without Complexity

The M23 V2 is designed to integrate easily into high-performance systems. Auto-sensing balanced XLR and single-ended RCA inputs simplify setup — no manual switching required. A three-position adjustable gain control (19dB / 23.9dB / 29.2dB in stereo) allows precise level matching with any preamplifier, including the NAD M66 Pre-Amplifier or M33 V2 Integrated Amplifier. A 12V trigger input with intelligent delay ensures reliable operation in multi-amplifier configurations.

Engineered for Performance and Reliability

NAD's advanced switch-mode power supply combines with a rigid all-alloy chassis to deliver high current with efficiency and low heat generation — the M23 V2 remains cool during extended listening sessions, drawing less than 0.5W in standby. The internal layout is carefully arranged to minimise interference and preserve signal integrity. The result is consistent performance over long listening sessions, with an amplifier focused entirely on the music.
