Both are portable players, $3700 against $3899. This page puts them side by side on the only three things a maker can be held to — power, output impedance and noise — and then asks the question that actually matters: which headphones do they treat differently?
The Luxury & Precision P6 Pro reaches 100 dB on 566 of the 567 models here, the Astell&Kern SP3000 on 565.
| Specification | Astell&Kern SP3000 | Luxury & Precision P6 Pro |
|---|---|---|
| Power into 32Ω | 340 mW | 180 mW |
| Power into 150Ω | 73 mW | 39 mW |
| Power into 300Ω | 36 mW | 20 mW |
| Power into 600Ω | 18 mW | 10.0 mW |
| Output impedance | 0.7 Ω | 0.2 Ω |
| Output noise | 3 µV unverified | not published |
| Price | $3700 | $3899 |
| Headphones it reaches 100 dB on out of 567 | 565 | 566 |
A figure marked not published is missing from the maker’s own material, which is not the same as being good or bad. Where one of these two publishes a number and the other does not, the comparison on that axis cannot be made at all — and saying so is more useful than guessing.
1 headphone reaches 100 dB on the Luxury & Precision P6 Pro but not on the Astell&Kern SP3000 — Moondrop PARA.
4 headphones are left alone by the Luxury & Precision P6 Pro under the one-eighth rule but coloured by the Astell&Kern SP3000 (Campfire Audio Chimera, Moondrop Armature Art 12, Softears Volume, 1 more).
565 of the 567 models here reach 100 dB on both. That is a power count and nothing more; whether either source suits a given headphone also depends on the two lines above.
Each has a page of its own with every power figure traced to what the maker published and a full headphone list: Astell&Kern SP3000 and Luxury & Precision P6 Pro. Or put either against your own headphones in the source comparison tool.
