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 | Advance Paris A8 APEX has more power - 75W against 40W into 8 ohms. That is about 2.7dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Noise floor | B | Advance Paris A8 APEX is the quieter design on paper - 100dB against 92dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | B | Advance Paris A8 APEX has a DAC on board; the other needs an external one, which is another box, another power lead and another purchase. |
| Phono stage | depends | Advance Paris A8 APEX has a built-in phono stage and PrimaLuna EVO 100 Power 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. |
| Use with a TV | depends | Only Advance Paris A8 APEX has HDMI, so the television can drive it directly and one remote controls the volume. If the system is for music only, this changes nothing. |
| Headphones | depends | Only Advance Paris A8 APEX has a headphone output. Worth something if you listen late, nothing if you never do. |
| Amplifier type | depends | PrimaLuna EVO 100 Power is Tube and Advance Paris A8 APEX is Hybrid. 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. |
| Shelf space | depends | PrimaLuna EVO 100 Power takes up about 32% less shelf area (1128cm² against 1660cm²). |
| Price | evenly matched | Priced within a few per cent of each other. |
| Watts per dollar | B | Advance Paris A8 APEX is the cheaper watt - about $40 per watt against $77. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A PrimaLuna EVO 100 Power B Advance Paris A8 APEX
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?
Advance Paris A8 APEX 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 - Advance Paris A8 APEX has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 40 watts is already more than most people ever use, and the extra 35 watts would be headroom you pay for and never hear. If you play records, Advance Paris A8 APEX 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.
