Short answer
Both are audio interfaces, both at $149.
The Arturia MiniFuse 1 reaches 100 dB on 562 of the 567 models here, the PreSonus Studio 24c on 552.
| Specification | Arturia MiniFuse 1 | PreSonus Studio 24c |
|---|---|---|
| Power into 32Ω | 139 mW | 27 mW |
| Power into 150Ω | 45 mW | 18 mW |
| Power into 300Ω | 24 mW | 8.8 mW |
| Power into 600Ω | 12 mW | 4.4 mW |
| Output impedance | 10 Ω | not published |
| Output noise | not published | not published |
| Price | $149 | $149 |
| Headphones it reaches 100 dB on out of 567 | 562 | 552 |
Not published means the maker leaves it out, so that axis cannot be compared.
| Load | Arturia MiniFuse 1 | PreSonus Studio 24c |

| 150 Ω | Derived | Derived |
| 300 Ω | Derived | Derived |
| 600 Ω | Derived | Derived |
Neither column is a maker’s power rating at these loads. Of the 280 sources here, 209 publish a figure at at least one load; these two do not, so every row above is derived — between or beyond the loads each maker did publish, holding output voltage as the maker’s own figures imply. The method understates rather than flatters, but it is still arithmetic rather than a rating.
10 headphones reach 100 dB on the Arturia MiniFuse 1 but not on the PreSonus Studio 24c — HiFiMAN HE-6se V2, HiFiMAN HE6 Remastered, HiFiMAN Susvara, 7 more.
552 of the 567 models here reach 100 dB on both.
Headroom is at a 100 dB SPL peak.
The widest gap on the list is the Campfire Audio Andromeda 2020: Arturia MiniFuse 1 has +10 dB of headroom there against +3 dB. 7 dB is about 5.2 times the power, which matters for peaks rather than for how loud the music sits.
The hiss columns are empty for Arturia MiniFuse 1 and PreSonus Studio 24c because neither maker publishes no output noise figure.

| Audio-Technica ATH-R70X | 470 Ω | 1.6 mW | +10 dB | +5 dB | not published | not published |
| Sennheiser HD 600 | 300 Ω | 6.6 mW | +6 dB | +1 dB | not published | not published |
| HiFiMAN Susvara | 60 Ω | 50 mW | +2 dB damping | -1 dB | not published | not published |
These two cost the same, $149, so price settles nothing. Out of the 567 models here, the Arturia MiniFuse 1 drives 10 models to 100 dB — and on the other side there is no such advantage at all.
Only published figures count here; blank axes are counted separately.
