Different price classes - Yamaha R-N600A costs roughly 1.6x what Emotiva BasX TA1 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 | B | Yamaha R-N600A 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. |
| Built-in DAC | B | Both decode on board, but only Yamaha R-N600A handles DSD. |
| Analogue inputs | B | Yamaha R-N600A takes more analogue sources - 4 against 3. |
| Room to grow | A | Only Emotiva BasX TA1 offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Shelf space | depends | Emotiva BasX TA1 takes up about 21% less shelf area (1371cm² against 1740cm²), and it is 81mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | A | Emotiva BasX TA1 costs less - $499 against $800 at list. |

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?
The usual trade-off: Yamaha R-N600A measures better, Emotiva BasX TA1 costs about 38% less. With most speakers in most rooms that gap is smaller in practice than it looks here. Think about the whole system: the roughly $301 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.
