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 |
|---|
| Noise floor | B | Denon PMA-900HNE is the quieter design on paper - 105dB against 90dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Streaming | evenly matched | The same streaming platforms and services on both. |
| Analogue inputs | B | Denon PMA-900HNE takes more analogue sources - 3 against 1. |
| Room to grow | evenly matched | The same expansion options on both. |
| Built-in sources | depends | Marantz MCR 60n has a CD player built in. That is one less box if you still play discs or listen to radio, and dead weight if you do not. |
| Shelf space | depends | Marantz MCR 60n takes up about 51% less shelf area (845cm² against 1710cm²), and it is 91mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | Denon PMA-900HNE costs less - $949 against $1,000 at list. |
A Marantz MCR 60n B Denon PMA-900HNE
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?
Denon PMA-900HNE has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is.
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.
