A valve amplifier against a solid-state one. They are not really rivals: they differ in character, in what they will drive and in what owning them involves, so start there rather than with the watts.
| Area | Better | Why |
|---|
| Power | B | Rotel A11 Tribute has more power - 50W against 28W into 8 ohms. That is about 2.5dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Room size | depends | We rate FiiO EA13 the better fit for desk or near-field listening, and Rotel A11 Tribute for a very large room. Match the amplifier to the room you actually have, not the one you want. |
| Noise floor | B | Rotel A11 Tribute is the quieter design on paper - 100dB against 97dB. Audible mainly with sensitive speakers in a quiet room. |
| Analogue inputs | evenly matched | The same number of line-level inputs (4). |
| Phono stage | depends | Rotel A11 Tribute has a built-in phono stage (MM) and FiiO EA13 does not. Decisive if you own a turntable, completely irrelevant if you do not - and an outboard phono stage is easy to add later either way. |
| Amplifier type | depends | FiiO EA13 is Tube and Rotel A11 Tribute is Solid State. Valve designs are usually warmer and softer at the limits and need their tubes replaced eventually; solid state is the lower-maintenance choice. This is a taste and ownership decision, not a quality one. |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | Rotel A11 Tribute is the cheaper watt - about $16 per watt against $28. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A FiiO EA13 B Rotel A11 Tribute
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?
Rotel A11 Tribute has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. 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 - Rotel A11 Tribute has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 28 watts is already more than most people ever use, and the extra 22 watts would be headroom you pay for and never hear. If you play records, Rotel A11 Tribute saves you buying a phono stage; if you do not, ignore that row entirely.
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.
