Both are desktop amplifiers, $499 against $399. 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 SMSL H200 reaches 100 dB on 567 of the 567 models here, the Schiit Valhalla 3 on 566.
| Specification | Schiit Valhalla 3 | SMSL H200 |
|---|---|---|
| Power into 32Ω | 750 mW | 2.0 W |
| Power into 150Ω | 286 mW | 499 mW |
| Power into 300Ω | 250 mW | 300 mW |
| Power into 600Ω | 125 mW | 150 mW |
| Output impedance | 25 Ω | <0.1 Ω |
| Output noise | not published | not published |
| Price | $499 | $399 |
| Headphones it reaches 100 dB on out of 567 | 566 | 567 |
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 SMSL H200 but not on the Schiit Valhalla 3 — Symphonium Titan.
535 headphones are left alone by the SMSL H200 under the one-eighth rule but coloured by the Schiit Valhalla 3 (64 Audio Aspire 1, 64 Audio Fourte, 64 Audio Nio, 532 more).
566 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 3 and SMSL H200. Or put either against your own headphones in the source comparison tool.
