Both are desktop amplifiers, $349 against $499. 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 Schiit Valhalla 3 reaches 100 dB on 566 of the 567 models here, the Schiit Valhalla 2 on 561.
| Specification | Schiit Valhalla 2 | Schiit Valhalla 3 |
|---|---|---|
| Power into 32Ω | 115 mW | 750 mW |
| Power into 150Ω | 426 mW | 286 mW |
| Power into 300Ω | 800 mW | 250 mW |
| Power into 600Ω | 450 mW | 125 mW |
| Output impedance | 14.0 Ω | 25 Ω |
| Output noise | not published | not published |
| Price | $349 | $499 |
| Headphones it reaches 100 dB on out of 567 | 561 | 566 |
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.
5 headphones reach 100 dB on the Schiit Valhalla 3 but not on the Schiit Valhalla 2 — Moondrop COSMO, Moondrop PARA, Symphonium Crimson, 2 more.
13 headphones are left alone by the Schiit Valhalla 2 under the one-eighth rule but coloured by the Schiit Valhalla 3 (AKG K612 Pro, Neumann NDH 20, Neumann NDH 30, 10 more).
561 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: Schiit Valhalla 2 and Schiit Valhalla 3. Or put either against your own headphones in the source comparison tool.
