That means it does one job, and only one job: it takes a low-level audio signal from your preamplifier and amplifies it to drive speakers. It does not select inputs. It does not control volume. It does not stream. It is purpose-built for clean amplification, nothing else.\u003c\/p\u003e\n\u003cp\u003eThis is the V2 — the second generation of NAD's flagship Masters Series stereo power amplifier. The original M23 launched in 2022 and quickly earned a reputation as one of the cleanest-measuring Class D amps at its price. The V2 takes that platform forward with the latest Purifi Eigentakt modules and additional system-integration features.\u003c\/p\u003e\n\u003cp\u003eThe M23 V2 sits in NAD's Masters Series, the top tier of NAD's lineup. To complete a system, pair it with a preamplifier or streaming preamp — NAD's own M66 BluOS Streaming DAC Preamplifier is the natural match. The M23 V2 can also bridge with a second M23 V2 (or with the M33 V2) for 700-watt monoblock operation.\u003c\/p\u003e\n\u003ch3\u003eEigentakt, Refined — The V2 Story\u003c\/h3\u003e\n\u003cp\u003eNAD describes the M23 V2 as a more advanced implementation of Purifi's amplifier technology — the second-generation Eigentakt modules. Eigentakt was the breakthrough Class D module that Bruno Putzeys (the engineer behind Hypex nCore) brought to Purifi Audio. The V2's Eigentakt modules further reduce distortion and improve linearity across the entire output range. Add intelligent 12V trigger sequencing and a three-position gain switch, and the V2 becomes easier to build into a serious system.\u003c\/p\u003e\n\u003ch3\u003eWhy does it matter? How does it improve your listening?\u003c\/h3\u003e\n\u003cp\u003eA power amplifier's job is invisible: pass the signal cleanly, drive the speakers, get out of the way. The numbers on the M23 V2 show how seriously NAD takes that job. Continuous output is 200 watts per channel into 8 ohms and 380 watts into 4 ohms — conservatively rated, both channels driven, across the full 20 Hz – 20 kHz audio band.\u003c\/p\u003e\n\u003cp\u003eTHD (total harmonic distortion) measures below 0.00069% on the XLR balanced input — well below what any human ear can detect. Signal-to-noise ratio is over 127 dB at full rated output. These are reference-grade numbers, in the range typically claimed only by amplifiers costing several times more.\u003c\/p\u003e\n\u003cp\u003eThe damping factor of over 800 (referenced to 8 ohms across most of the audible range) is the part most listeners feel rather than read. Damping factor measures how tightly an amplifier controls a speaker's bass driver — higher numbers mean less overshoot and tighter, more defined bass. Pair the M23 V2 with a difficult speaker load and it stays composed.\u003c\/p\u003e\n\u003cp\u003eFor bigger rooms or more demanding speakers, the M23 V2 can be switched to mono bridge mode for 700 watts continuous into 8 ohms — over 1,000 W of dynamic peak power.\u003c\/p\u003e\n\u003ch3\u003eWhat's different about how it's built?\u003c\/h3\u003e\n\u003cp\u003eThe output stage uses second-generation Purifi Eigentakt modules — the latest version of the Class D topology Bruno Putzeys developed at Purifi Audio. Eigentakt's distinguishing trait is load-invariance: the amplifier's frequency response stays flat regardless of what speaker it's driving. Most Class D amplifiers have small response variations into challenging loads; Eigentakt's mathematical modeling closes those gaps.\u003c\/p\u003e\n\u003cp\u003eNAD manufactures the Eigentakt modules under license from Purifi, then pairs them with NAD's own switch-mode power supply, custom input stages, and multi-layer circuit boards. The combination delivers the load-invariant behavior of Eigentakt at the chassis level.\u003c\/p\u003e\n\u003cp\u003eAuto-sensing inputs detect whether a signal is present on the balanced XLR or single-ended RCA jack and switch automatically. A three-position gain switch lets you match the M23 V2's input sensitivity to your preamp. The intelligent 12V trigger output adds a one-second delay from the 12V input — that delay prevents inrush surge spikes when you're sequencing multiple amplifiers in a high-end stack.\u003c\/p\u003e\n\u003cp\u003eThe chassis is all-alloy with rigid panels and magnetic iso-point feet — design that contributes to keeping internal resonances from coloring the sound and gives the M23 V2 the build feel of a Masters Series component.\u003c\/p\u003e\n\u003ch3\u003eWho is this best for?\u003c\/h3\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You're building a serious separates system and want one of the cleanest-measuring stereo amplifiers on the market.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You already own (or are buying) a high-end preamplifier — NAD's M66 streaming preamp, or any preamp with RCA or balanced XLR outputs.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You drive demanding floorstanding speakers in a medium-to-large room and want headroom to spare without the heat and weight of Class A\/B.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You may want to scale up later — running two M23 V2s in bridged mode delivers 700 watts per channel of mono power, or pair one M23 V2 with the M33 V2 for a similar bridged configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔️\" width=\"15\"\u003e You're integrating into a custom-installed system — the 12V trigger with intelligent delay sequences cleanly with other amplifiers and source components.\u003c\/p\u003e\n\u003ch3\u003eHow does it connect to your system?\u003c\/h3\u003e\n\u003cp\u003eThis is a power amplifier only — you'll need a preamplifier to feed it a signal.

The M23 V2 is a power amplifier — it doesn't have inputs you can switch between, doesn't control volume, and doesn't have a streamer or DAC built in. NAD's own M66 BluOS Streaming DAC Preamplifier is the natural Masters Series match. Any preamp with balanced XLR or single-ended RCA outputs will work.\u003c\/p\u003e\n\u003ch3\u003eIs the M23 V2 a good match for my speakers?\u003c\/h3\u003e\n\u003cp\u003eThe M23 V2 has 200 W per channel continuous, dynamic power to 520 W into 4 Ω, and a damping factor over 800 — enough to drive nearly any home loudspeaker, including current-hungry floorstanders. The right speaker pairing depends on your room and listening tastes. Call us at \u003ca href=\"tel:+18009420220\"\u003e800-942-0220\u003c\/a\u003e and we'll help you dial it in.\u003c\/p\u003e\n\u003ch3\u003eWhat are the differences between Class A, Class A\/B, and Class D amplifiers? Which one is this?\u003c\/h3\u003e\n\u003cp\u003eThe M23 V2 uses HybridDigital Purifi Eigentakt — a second-generation Class D design. Class A runs the output transistors fully on (clean, but hot and inefficient). Class A\/B blends both modes — the traditional analog approach, still common in expensive amps.\u003c\/p\u003e\n\u003cp\u003eClass D switches the output transistors rapidly. The benefit is very high efficiency and very low heat. Eigentakt is a modern Class D module developed by Bruno Putzeys (the engineer behind Hypex nCore), known for measurable performance at or beyond the best Class A\/B designs.\u003c\/p\u003e\n\u003ch3\u003eWhat's different about the V2 versus the original M23?\u003c\/h3\u003e\n\u003cp\u003eThe V2 uses the latest generation of Purifi Eigentakt modules — further reducing distortion and improving linearity across the output range compared with the original. NAD also added system-friendly features for the V2: a three-position gain switch, intelligent 12V trigger with one-second delay, and refined casework with magnetic iso-point feet.\u003c\/p\u003e\n\u003ch3\u003eCan I bridge two M23 V2s for more power?\u003c\/h3\u003e\n\u003cp\u003eYes. Each M23 V2 has a bridge mode that turns it into a 700-watt mono amplifier into 8 Ω. Running two M23 V2s in bridged mode gives you 700 W per channel — enough for the most demanding speakers and largest rooms. You can also pair one M23 V2 in bridged mode with the M33 V2 streaming amp for the same configuration on a budget.\u003c\/p\u003e\n\u003ch3\u003eDo I need balanced XLR cables, or will RCA work?\u003c\/h3\u003e\n\u003cp\u003eEither works. The M23 V2 has both balanced XLR and single-ended RCA inputs, and they're auto-sensing — the amp detects which one has a live signal and switches automatically. Balanced XLR has marginally better measured performance (THD is lower on XLR) and rejects noise on long cable runs. RCA is more common and works fine for typical home runs.\u003c\/p\u003e\n\u003ch3\u003eWhat does the gain switch do?\u003c\/h3\u003e\n\u003cp\u003eThe three-position gain switch lets you match the M23 V2's input sensitivity to your preamp. Some preamps have lower output voltages than others, and some integrated systems require matching gain across multiple amplifiers. The switch is set during installation and rarely touched again.\u003c\/p\u003e\n\u003ch3\u003eHow does this compare to the next NAD model up?\u003c\/h3\u003e\n\u003cp\u003eThe M23 V2 is the top stereo power amplifier in NAD's current Masters Series lineup. Above it sits only the Masters Series multi-channel amplifiers (M28, M27) for home theater. The M33 V2 is the comparable Masters Series streaming integrated, but it includes the preamp, DAC, BluOS streamer, and Dirac Live in one chassis — different approach, similar audiophile-tier engineering. Call us and we'll help you weigh the trade-offs.\u003c\/p\u003e\n\u003ch3\u003eDoes this run hot?\u003c\/h3\u003e\n\u003cp\u003eNo. Class D amplifiers — including Eigentakt — are highly efficient. Most of the input power becomes output power rather than heat. The M23 V2 stays cool to the touch in normal use and doesn't need the heavy heatsinking of traditional Class A\/B amplifiers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNAD Masters M23 V2 Stereo Power Amplifier\u003c\/li\u003e\n\u003cli\u003eDetachable mains power cord\u003c\/li\u003e\n\u003cli\u003eOwner's manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Audio Advisor?\u003c\/h3\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e \u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e — Since 1981, we've helped over a million music lovers find the right gear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e \u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e — Take your time.
