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 NOVA A-i130 has more power - 125W against 100W into 8 ohms. That is about 1dB, 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 (150W and 186W). |
| Noise floor | B | Advance Paris NOVA A-i130 is the quieter design on paper - 112dB against 104dB. Audible mainly with sensitive speakers in a quiet room. |
| Use with a TV | depends | Only Advance Paris NOVA A-i130 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. |
| Room to grow | evenly matched | The same expansion options on both. |
| Amplifier type | depends | Luxman L-505Z is Solid State and Advance Paris NOVA A-i130 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 | Advance Paris NOVA A-i130 takes up about 14% less shelf area (1728cm² against 1998cm²), and it is 52mm shallower, which is the measurement that decides whether a rack door shuts. |
| Price | B | Advance Paris NOVA A-i130 costs less - $6,499 against $6,995 at list. |
| Watts per dollar | B | Advance Paris NOVA A-i130 is the cheaper watt - about $52 per watt against $70. A blunt measure, and it says nothing about how either sounds, but it is the honest one for raw output. |
A Luxman L-505Z B Advance Paris NOVA A-i130
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 NOVA A-i130 has the edge on paper, though not by much. The rows marked "depends" are more likely to decide this than the score is. If this sits under a television, Advance Paris NOVA A-i130 is the one to buy - HDMI ARC means the TV remote controls the volume and there is no second box in the way.
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.
