Different price classes - Naim Nova PE costs roughly 1.7x what T+A M 200 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 | T+A M 200 has more power - 210W against 150W into 8 ohms. That is about 1.5dB, which is a small step in loudness but real headroom on peaks. |
| Grip on hard loads | A | T+A M 200 holds up better into a 4-ohm load: its output nearly doubles to 420W, where the other increases strongly. That matters with demanding speakers far more than the 8-ohm figure does. |
| Built-in DAC | B | Naim Nova PE 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 (2). |
| Use with a TV | depends | Only Naim Nova PE 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. |
| Headphones | depends | Only Naim Nova PE has a headphone output. Worth something if you listen late, nothing if you never do. |
| Price | A | T+A M 200 costs less - $5,995 against $9,999 at list. |
| Watts per dollar | A | T+A M 200 is the cheaper watt - about $29 per watt against $67. 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?
T+A M 200 is the easier recommendation: it leads on most of the measured areas and costs less. Take Naim Nova PE if one of the "depends" rows above describes your system. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - T+A M 200 is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. If this sits under a television, Naim Nova PE is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way.
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.
