Siblings in NAD's Masters range, so they share a design and a house sound. It comes down to power, features and price.
| Area | Better | Why |
|---|
| Power | A | NAD M32 has more power - 150W against 100W into 8 ohms. That is about 1.8dB, which is a small step in loudness but real headroom on peaks. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output barely increases (150W and 100W). |
| Noise floor | A | NAD M32 is the quieter design on paper - 124dB against 90dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Both decode on board, but only NAD Masters Series M10 V2 handles MQA. |
| Analogue inputs | A | NAD M32 takes more analogue sources - 4 against 2. |
| Phono stage | depends | NAD M32 has a built-in phono stage (MM and MC) and NAD Masters Series M10 V2 does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Use with a TV | depends | Only NAD Masters Series M10 V2 has HDMI eARC, so the television can drive it directly and one remote controls the volume. If the system is for music only, this changes nothing. |
| Headphones | depends | Only NAD M32 has a headphone output. Worth something if you listen late, nothing if you never do. |
| Shelf space | depends | NAD Masters Series M10 V2 takes up about 64% less shelf area (606cm² against 1688cm²), and it is 110mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | NAD Masters Series M10 V2 costs less - $2,999 against $3,299 at list. |
| Watts per dollar | A | NAD M32 is the cheaper watt - about $22 per watt against $30. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both amplifiers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
NAD M32 leads across most of the measured areas for a fairly modest premium, so it is the easier pick if the budget stretches. NAD Masters Series M10 V2 is the one to take if it does not. If you play records, NAD M32 saves you buying a phono stage; if you do not, ignore that row entirely. If this sits under a television, NAD Masters Series M10 V2 is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way.
What a spec sheet cannot show: how either sounds with your speakers, how the controls feel day to day, and what the app is like to live with - which is where most all-in-one amplifiers are actually won or lost. Power figures are the manufacturers' own and are not measured to a common standard, so treat small differences as noise. If you can hear both, that will tell you more than any row above.
