Different price classes - Yamaha R-N1000A costs roughly 1.8x what Emotiva BasX TA2+ 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 | Emotiva BasX TA2+ has more power - 135W against 100W into 8 ohms. That is about 1.3dB, which is a small step in loudness but real headroom on peaks. |
| Built-in DAC | B | Both decode on board, but only Yamaha R-N1000A handles DSD. |
| Analogue inputs | A | Emotiva BasX TA2+ takes more analogue sources - 4 against 3. |
| Use with a TV | depends | Only Yamaha R-N1000A has HDMI ARC, 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 | evenly matched | The same expansion options on both. |
| Price | A | Emotiva BasX TA2+ costs less - $1,299 against $2,300 at list. |
| Watts per dollar | A | Emotiva BasX TA2+ is the cheaper watt - about $10 per watt against $23. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Emotiva BasX TA2+ B Yamaha R-N1000A
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?
Emotiva BasX TA2+ is the easier recommendation: it leads on most of the measured areas and costs less. Take Yamaha R-N1000A if one of the "depends" rows above describes your system. If this sits under a television, Yamaha R-N1000A is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way. Think about the whole system: the roughly $1,001 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.
