These are not the same size of amplifier: Marantz PM-10 has roughly 3.3x the power of Marantz Model 60n. That is about 5.2dB, so it is a question of room size and how hard your speakers are to drive, not of one being the better amplifier.
| Area | Better | Why |
|---|
| Power | B | Marantz PM-10 has more power - 200W against 60W into 8 ohms. That is about 5.2dB - a different class of amplifier rather than a bigger version of the same one, and far more than most rooms will ever ask for. |
| Room size | depends | We rate Marantz Model 60n the better fit for desk or near-field listening, a small room and a mid-size room, and Marantz PM-10 for a large room and a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Grip on hard loads | B | Marantz PM-10 holds up better into a 4-ohm load: its output nearly doubles to 400W, where the other increases modestly. That matters with demanding speakers far more than the 8-ohm figure does. |
| Noise floor | evenly matched | Much the same signal-to-noise ratio (113dB vs 111dB). |
| Built-in DAC | A | Marantz Model 60n has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Streaming | A | Only Marantz Model 60n has AirPlay 2, Roon and HEOS. |
| Analogue inputs | B | Marantz PM-10 takes more analogue sources - 5 against 3. |
| Room to grow | A | Only Marantz Model 60n offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Amplifier class | depends | Marantz Model 60n is Class A/B and Marantz PM-10 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 | A | Marantz Model 60n costs less - $1,600 against $8,999 at list. |
| Watts per dollar | A | Marantz Model 60n is the cheaper watt - about $27 per watt against $45. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Marantz Model 60n B Marantz PM-10
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?
Marantz Model 60n has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If your speakers are a difficult load - 4 ohms nominal, big woofers, or a sensitivity in the low 80s - Marantz PM-10 is the safer partner, because how an amplifier behaves when the impedance drops matters more than its 8-ohm rating. Start with the room. In a large or open-plan room, or with speakers that are hard to drive - low sensitivity, or an impedance that dips - Marantz PM-10 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 60 watts is already more than most people ever use, and the extra 140 watts would be headroom you pay for and never hear - we rate Marantz PM-10 poorly for near-field use for exactly that reason.
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.
