Both are audio interfaces, $299 against $299. 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 MiniFuse 4 reaches 100 dB on 562 of the 567 models here, the Universal Audio Volt 276 on 558.

| Headphones it reaches 100 dB on out of 567 | 562 | 558 |
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.
4 headphones reach 100 dB on the Arturia MiniFuse 4 but not on the Universal Audio Volt 276 — Moondrop PARA 2, Moondrop VENUS, Symphonium Triton, 1 more.
558 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 MiniFuse 4 and Universal Audio Volt 276. Or put either against your own headphones in the source comparison tool.
