Siblings in PrimaLuna's EVO range, so they share a design and a house sound. It comes down to power, features and price.
| Area | Better | Why |
|---|
| Power | evenly matched | Effectively the same output - 42W against 40W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Room size | depends | We rate PrimaLuna EVO 300 Integrated the better fit for a very large room, and PrimaLuna EVO 100 Integrated for desk or near-field listening. Match the amplifier to the room you actually have, not the one you want. |
| Analogue inputs | evenly matched | The same number of line-level inputs (5). |
| Shelf space | depends | PrimaLuna EVO 100 Integrated takes up about 28% less shelf area (1128cm² against 1559cm²). |
| Price | B | PrimaLuna EVO 100 Integrated costs less - $3,295 against $5,495 at list. |
| Watts per dollar | B | PrimaLuna EVO 100 Integrated is the cheaper watt - about $82 per watt against $131. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A PrimaLuna EVO 300 Integrated B PrimaLuna EVO 100 Integrated
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?
PrimaLuna EVO 100 Integrated 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 $2,200 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.
