Siblings in Yamaha's R-N range, so they share a design and a house sound. It comes down to power, features and price.
| Area | Better | Why |
|---|
| Power | evenly matched | Effectively the same output - 100W against 90W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Streaming | evenly matched | The same streaming platforms and services on both. |
| Room to grow | evenly matched | The same expansion options on both. |
| Shelf space | depends | Yamaha R-N1000A takes up about 13% less shelf area (1830cm² against 2106cm²), and it is 64mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | A | Yamaha R-N1000A costs less - $2,300 against $5,000 at list. |
| Watts per dollar | A | Yamaha R-N1000A is the cheaper watt - about $23 per watt against $56. 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?
Yamaha R-N1000A 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 $2,700 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.
