No single best amplifier here. What decides it is what you have to drive, what you need to plug in, and how much of the system you want in one box.
| Area | Better | Why |
|---|
| Power | B | NAD C 368 BluOS-2i has more power - 80W against 60W into 8 ohms. That is about 1.2dB, which is a small step in loudness but real headroom on peaks. |
| Room size | depends | We rate Hegel H95 the better fit for desk or near-field listening and a small room, and NAD C 368 BluOS-2i 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. |
| Speaker load rating | A | Hegel H95 is rated down to 2 ohms against 4, so it is the safer partner for a low-impedance speaker. |
| Noise floor | evenly matched | Much the same signal-to-noise ratio (100dB vs 98dB). |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Analogue inputs | evenly matched | The same number of line-level inputs (2). |
| Phono stage | depends | NAD C 368 BluOS-2i has a built-in phono stage (MM) and Hegel H95 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. |
| Room to grow | evenly matched | The same expansion options on both. |
| Amplifier class | depends | Hegel H95 is Class A/B and NAD C 368 BluOS-2i 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 | Hegel H95 takes up about 18% less shelf area (1505cm² against 1840cm²), and it is 73mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | NAD C 368 BluOS-2i is the cheaper watt - about $25 per watt against $33. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Hegel H95 B NAD C 368 BluOS-2i
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 C 368 BluOS-2i has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If you play records, NAD C 368 BluOS-2i 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.
