These are not the same size of amplifier: NAD Masters Series M10 V2 has roughly 2.5x the power of NAD C316BEE V2. That is about 4dB, so it is a question of room size and how hard your speakers are to drive, not of one being the better amplifier.
| Area | Better | Why |
|---|
| Power | B | NAD Masters Series M10 V2 has more power - 100W against 40W into 8 ohms. That is about 4dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate NAD C316BEE V2 the better fit for desk or near-field listening and a small room, and NAD Masters Series M10 V2 for a mid-size room, a large room and a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output barely increases (40W and 100W). |
| Noise floor | A | NAD C316BEE V2 is the quieter design on paper - 95dB against 90dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | NAD Masters Series M10 V2 has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Streaming | B | Only NAD Masters Series M10 V2 has AirPlay 2, Roon and BluOS. |
| Analogue inputs | A | NAD C316BEE V2 takes more analogue sources - 5 against 2. |
| Phono stage | depends | NAD C316BEE V2 has a built-in phono stage (MM) 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. |
| Room to grow | B | Only NAD Masters Series M10 V2 offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Headphones | depends | Only NAD C316BEE V2 has a headphone output. Worth something if you listen late, nothing if you never do. |
| Amplifier class | depends | NAD C316BEE V2 is Class A/B and NAD Masters Series M10 V2 is Class D. Class A/B runs warm and is the long-established mainstream choice; Class D runs cool and draws almost nothing at idle. Modern examples of both measure well - judge by the rest of the page. |
| Shelf space | depends | NAD Masters Series M10 V2 takes up about 52% less shelf area (606cm² against 1253cm²). |
| Price | A | NAD C316BEE V2 costs less - $499 against $2,999 at list. |
| Watts per dollar | A | NAD C316BEE V2 is the cheaper watt - about $12 per watt against $30. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A NAD C316BEE V2 B NAD Masters Series M10 V2
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 is ahead, but on only 1 of the measured areas, and it costs about 6x the price. That is a lot of money for a narrow margin - NAD C316BEE V2 is the sensible buy unless a specific feature above decides it for you. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - NAD Masters Series M10 V2 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 40 watts is already more than most people ever use, and the extra 60 watts would be headroom you pay for and never hear - we rate NAD Masters Series M10 V2 poorly for near-field use for exactly that reason. If you play records, NAD C316BEE V2 saves you buying a phono stage; if you do not, ignore that row entirely.
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.
