Both are desktop amplifiers, $699 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?
On raw power they are level: each reaches 100 dB on 566 of the 567 non-electrostatic models here.
| Specification | Rupert Neve RNHP | Schiit Valhalla 3 |
|---|---|---|
| Power into 32Ω | 262 mW | 750 mW |
| Power into 150Ω | 175 mW | 286 mW |
| Power into 300Ω | 88 mW | 250 mW |
| Power into 600Ω | 44 mW | 125 mW |
| Output impedance | 0.08 Ω | 25 Ω |
| Output noise | 8.03 µV | not published |
| Price | $699 | $499 |
| Headphones it reaches 100 dB on out of 567 | 566 | 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.
On power they are interchangeable across this whole database: there is no headphone here that one reaches 100 dB on and the other does not.
535 headphones are left alone by the Rupert Neve RNHP 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: Rupert Neve RNHP and Schiit Valhalla 3. Or put either against your own headphones in the source comparison tool.
