Size, drawn to scale

Both amplifiers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.

One scale for both, aligned at the back panels the way they would sit against a wall, so the deeper one visibly stands further out.

PS Audio PMG S200 needs about 33% more shelf area. PS Audio PMG S200 is 92mm deeper - the measurement that decides whether a rack door closes. PS Audio PMG S200 is 116mm taller.

Inputs and Outputs

The input and output selections that are offered is an important factor when comparing two amplifiers. Here you can find how the I/O selections of the PS Audio PMG S200 and Naim NAP 300 DR differs from each other.

Outputs

Balanced connections

PS Audio PMG S200 has balanced XLR connections and Naim NAP 300 DR does not. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more it is worth. Whether it also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same either way.

Verdict

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	evenly matched	Effectively the same output - 100W against 90W into 8 ohms is under 1dB, which is not an audible difference in loudness.
Analogue inputs	evenly matched	The same number of line-level inputs (1).
Amplifier class	depends	PS Audio PMG S200 is Class A/AB and Naim NAP 300 DR is Class A/B. Class A/B runs warm and is the long-established mainstream choice. Modern examples of both measure well - judge by the rest of the page.
Shelf space	depends	Naim NAP 300 DR takes up about 25% less shelf area (1356cm² against 1806cm²), and it is 92mm shallower, which is the measurement that decides whether a rack door shuts.
Price	A	PS Audio PMG S200 costs less - $7,999 against $12,700 at list.
Watts per dollar	A	PS Audio PMG S200 is the cheaper watt - about $80 per watt against $141. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output.

A PS Audio PMG S200 B Naim NAP 300 DR
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?

PS Audio PMG S200 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 $4,701 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.
