Both are audio interfaces, $750 against $249. 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 EVO 16 reaches 100 dB on 558 of the 567 models here, the Audient EVO 8 on 543.
| Specification | Audient EVO 16 | Audient EVO 8 |
|---|---|---|
| Power into 32Ω | 87 mW | 22 mW |
| Power into 150Ω | 49 mW | 14 mW |
| Power into 300Ω | 32 mW | 11 mW |
| Power into 600Ω | 24 mW | 10 mW |
| Output impedance | 50 Ω | 50 Ω |
| Output noise | not published | not published |
| Price | $750 | $249 |
| Headphones it reaches 100 dB on out of 567 | 558 | 543 |
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.
15 headphones reach 100 dB on the Audient EVO 16 but not on the Audient EVO 8 — Dan Clark Audio AEON 2 Closed, Dan Clark Audio AEON 2 Noire, Dan Clark Audio AEON 2 Open, 12 more.
543 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 EVO 16 and Audient EVO 8. Or put either against your own headphones in the source comparison tool.
