One is a streaming all-in-one and the other is an amplifier. Judge them on how many boxes you want and what you already own, not on the spec sheet alone.
| Area | Better | Why |
|---|
| Power | evenly matched | Effectively the same output - 60W against 60W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Noise floor | A | Eversolo Play is the quieter design on paper - 109dB against 100dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | A | Both decode on board. Eversolo Play goes higher - 768kHz against 192kHz. Very few recordings exist above 192kHz, so treat this as headroom, not as sound quality. |
| Streaming | evenly matched | Only Eversolo Play has Roon. Neither list is longer in a way that matters - check the one service you actually pay for. |
| Analogue inputs | B | Rotel A12 takes more analogue sources - 4 against 2. |
| Amplifier class | depends | Eversolo Play is Class D and Rotel A12 is Class A/B. Class D runs cool and draws almost nothing at idle; 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 | Eversolo Play takes up about 68% less shelf area (529cm² against 1633cm²), and it is 148mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | A | Eversolo Play costs less - $699 against $800 at list. |

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?
Eversolo Play 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.
