Different price classes - Advance Paris NOVA A-i130 costs roughly 2.2x what Advance Paris A8 APEX does. Expect it to lead on paper; the question is whether you will hear the difference through the speakers you own.
| Area | Better | Why |
|---|
| Power | B | Advance Paris NOVA A-i130 has more power - 125W against 75W into 8 ohms. That is about 2.2dB, so it plays usefully louder before it runs out and has more in hand on peaks. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output increases modestly (110W and 186W). |
| Noise floor | B | Advance Paris NOVA A-i130 is the quieter design on paper - 112dB against 100dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | A | 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. |
| Room to grow | B | Only Advance Paris NOVA A-i130 offers preamp outputs - which decides whether you can add a subwoofer or a power amplifier later without replacing the box. |
| Room correction | B | Advance Paris NOVA A-i130 has room correction. In an awkward room that does more for the sound than any other difference on this page. |
| Price | A | Advance Paris A8 APEX costs less - $2,999 against $6,499 at list. |
| Watts per dollar | A | Advance Paris A8 APEX is the cheaper watt - about $40 per watt against $52. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |

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?
The usual trade-off: Advance Paris NOVA A-i130 measures better, Advance Paris A8 APEX costs about 54% less. With most speakers in most rooms that gap is smaller in practice than it looks here. 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 NOVA A-i130 has the headroom, and headroom is what stops an amplifier hardening up on peaks. At desk distance or in a small room, 75 watts is already more than most people ever use, and the extra 50 watts would be headroom you pay for and never hear. If you already own a DAC or a streamer, the built-in one is money you are paying twice for, and Advance Paris NOVA A-i130 becomes the more rational buy.
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.
