Both are audio interfaces, $599 against $149. 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 Arturia AudioFuse Rev2 reaches 100 dB on 564 of the 567 models here, the Arturia MiniFuse 2 on 562.
| Specification | Arturia AudioFuse Rev2 | Arturia MiniFuse 2 |
|---|---|---|
| Power into 32Ω | 187 mW | 139 mW |
| Power into 150Ω | 40 mW | 45 mW |
| Power into 300Ω | 20 mW | 24 mW |
| Power into 600Ω | 10.0 mW | 12 mW |
| Output impedance | 33 Ω | 10 Ω |
| Output noise | not published | not published |
| Price | $599 | $149 |
| Headphones it reaches 100 dB on out of 567 | 564 | 562 |
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.
2 headphones reach 100 dB on the Arturia AudioFuse Rev2 but not on the Arturia MiniFuse 2 — Moondrop COSMO, Symphonium Helios.
35 headphones are left alone by the Arturia MiniFuse 2 under the one-eighth rule but coloured by the Arturia AudioFuse Rev2 (AKG K612 Pro, Audeze LCD-3, Audeze LCD-4, 32 more).
562 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: Arturia AudioFuse Rev2 and Arturia MiniFuse 2. Or put either against your own headphones in the source comparison tool.
