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 - 44W against 40W into 8 ohms is under 1dB, which is not an audible difference in loudness. |
| Room size | depends | We rate PrimaLuna EVO 300 Power 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 | B | PrimaLuna EVO 100 Integrated takes more analogue sources - 5 against 1. |
| Headphones | depends | Only PrimaLuna EVO 100 Integrated has a headphone output. Worth something if you listen late, nothing if you never do. |
| 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 $4,695 at list. |
| Watts per dollar | B | PrimaLuna EVO 100 Integrated is the cheaper watt - about $82 per watt against $107. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A PrimaLuna EVO 300 Power 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 is the easier recommendation: it leads on most of the measured areas and costs less. Take PrimaLuna EVO 300 Power if one of the "depends" rows above describes your system. Think about the whole system: the roughly $1,400 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.
