Both are audio interfaces, $1300 against $999. 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 Audient iD48 reaches 100 dB on 566 of the 567 models here, the Universal Audio Volt 876 on 565.
| Specification | Audient iD48 | Universal Audio Volt 876 |

| Power into 300Ω | 168 mW | 65 mW |
| Power into 600Ω | 126 mW | 35 mW |
| Output impedance | 50 Ω | not published |

| Price | $1300 | $999 |
| Headphones it reaches 100 dB on out of 567 | 566 | 565 |
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 Audient iD48 but not on the Universal Audio Volt 876 — Moondrop PARA.
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: Audient iD48 and Universal Audio Volt 876. Or put either against your own headphones in the source comparison tool.
