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 | Technics SU-R1000 has more power - 150W against 100W into 8 ohms. That is about 1.8dB, which is a small step in loudness but real headroom on peaks. |
| Room size | depends | We rate T+A PA 2000 R the better fit for a small room, and Technics SU-R1000 for a large room and a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Built-in DAC | B | Technics SU-R1000 has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Analogue inputs | evenly matched | The same number of line-level inputs (5). |
| Phono stage | depends | Technics SU-R1000 has a built-in phono stage (MM/MC on RCA plus MC on XLR, four-level gain adjustment) and T+A PA 2000 R 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. |
| Amplifier class | depends | T+A PA 2000 R is Class A/B and Technics SU-R1000 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. |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | Technics SU-R1000 is the cheaper watt - about $80 per watt against $115. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A T+A PA 2000 R B Technics SU-R1000
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?
Technics SU-R1000 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, Technics SU-R1000 saves you buying a phono stage; if you do not, ignore that row entirely. If you already own a DAC or a streamer, the built-in one is money you are paying twice for, and T+A PA 2000 R becomes the more rational buy.
What a spec sheet cannot show: how either sounds with your speakers, how the interface feels 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.
