Different price classes - Naim Uniti Nova costs roughly 2.3x what NAD Masters Series M10 V2 does. Expect it to lead on paper; the question is whether you will hear the difference through the speakers you own.
| Area | Better | Why |
|---|
| Power | A | NAD Masters Series M10 V2 has more power - 100W against 80W into 8 ohms. That is about 1dB, which is a small step in loudness but real headroom on peaks. |
| Room size | depends | We rate NAD Masters Series M10 V2 the better fit for a large room and a very large room, and Naim Uniti Nova for a small room. Match the amplifier to the room you actually have, not the one you want. |
| Built-in DAC | B | Both decode on board. Naim Uniti Nova goes higher - 384kHz against 192kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | evenly matched | Only NAD Masters Series M10 V2 has BluOS; only Naim Uniti Nova has Chromecast. Neither list is longer in a way that matters - check the one service you actually pay for. |
| Analogue inputs | evenly matched | The same number of line-level inputs (2). |
| Room to grow | evenly matched | The same expansion options on both. |
| Headphones | depends | Only Naim Uniti Nova has a headphone output. Worth something if you listen late, nothing if you never do. |
| Amplifier class | depends | NAD Masters Series M10 V2 is Class D and Naim Uniti Nova is Class A/B. Class D runs cool and draws almost nothing at idle; Class A/B runs warm and is the long-established mainstream choice. Modern examples of both measure well - judge by the rest of the page. |
| Shelf space | depends | NAD Masters Series M10 V2 takes up about 56% less shelf area (606cm² against 1371cm²), and it is 38mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | A | NAD Masters Series M10 V2 costs less - $2,999 against $6,899 at list. |
| Watts per dollar | A | NAD Masters Series M10 V2 is the cheaper watt - about $30 per watt against $86. 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 Masters Series M10 V2 has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. Think about the whole system: the roughly $3,900 saved by taking the cheaper one would buy better speakers or a subwoofer, which does more for the sound than the difference between two competent amplifiers.
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.
