Both are Advance Paris, from different ranges - the engineering approach is shared and the differences are mostly in power, connectivity and price.
| Area | Better | Why |
|---|
| Power | B | Advance Paris A12 Classic has more power - 190W against 125W into 8 ohms. That is about 1.8dB, which is a small step in loudness but real headroom on peaks. |
| Grip on hard loads | evenly matched | Both behave much the same into 4 ohms - output increases modestly (186W and 280W). |
| Noise floor | A | Advance Paris NOVA A-i130 is the quieter design on paper - 104dB against 100dB. Audible mainly with sensitive speakers in a quiet room. |
| Built-in DAC | evenly matched | Both have a DAC on board with much the same capability. |
| Room to grow | evenly matched | The same expansion options on both. |
| Room correction | A | Advance Paris NOVA A-i130 has room correction (Manual DSP EQ: measure in REW with your own mic, load the file by USB). In an awkward room that does more for the sound than any other difference on this page. |
| Shelf space | depends | Advance Paris NOVA A-i130 takes up about 15% less shelf area (1728cm² against 2043cm²), and it is 72mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | Advance Paris A12 Classic costs less - $4,499 against $6,499 at list. |
| Watts per dollar | B | Advance Paris A12 Classic is the cheaper watt - about $24 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and the speakers you already own settle it. Think about the whole system: the roughly $2,000 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.
